For decades, the Science of Reading has shown how children learn to read. The research is clear: reading is not a natural process. It must be explicitly taught with systematic instruction in phonics, phonemic awareness, vocabulary, fluency, morphology, and comprehension.

Long before the term became a national movement, Core Knowledge Language Arts® (CKLA) was built on this science.

 

Built on Research from the Start

  • Development began in 2010
  • Multiple pilot phases with schools nationwide
  • Full first edition released in 2014

CKLA was one of the first comprehensive curricula explicitly created from the findings of the Science of Reading—making it a true leader in the movement.

 

What Sets CKLA Apart

1. Systematic Phonics

The Skills Strand provides daily, sequenced phonics lessons starting in Kindergarten. Students learn to decode step by step, aligned with decades of research.

2. Morphology Matters

Older students dive into roots, prefixes, and suffixes to unlock vocabulary and confidently tackle complex texts.

3. Building Knowledge for Comprehension

Starting in Kindergarten, the Knowledge Strand immerses students in history, science, literature, and the arts. Research shows that this background knowledge is critical for comprehension.

4. Oral Language and Writing

From early read-aloud discussions to daily writing tied to content, CKLA reinforces the connection between speaking, reading, and writing.

 

The Simple View of Reading in Action

Reading requires both:

  • Word Recognition → phonics, decoding, spelling, fluency
  • Language Comprehension → vocabulary, knowledge, oral understanding

CKLA is unique in systematically addressing both sides of this equation.

 

Why It Matters

As schools across the country embrace the Science of Reading, CKLA stands out as a program leading the way for more than a decade.

  • Research-based
  • Classroom-proven
  • Comprehensive and coherent

CKLA doesn’t just align with the Science of Reading—it embodies it.

CKLA was one of the first Science of Reading curricula. Today, it remains one of the strongest.

It equips teachers.
It empowers students.
It delivers results.

In the ongoing discussions about what children should be learning in school, it is crucial to consider whether the curriculum resonates with the diverse world our students live in. This is where the Core Knowledge curriculum demonstrates its strength, often more comprehensively than many realize.

The Core Knowledge approach, pioneered by E.D. Hirsch Jr., is founded on the belief that a shared body of knowledge supports students in becoming proficient readers, critical thinkers, and informed citizens. It encompasses a meticulously organized array of subjects, including literature, history, science, and the arts, starting in kindergarten and extending through 8th grade.

While some may associate Core Knowledge predominantly with classic Western content, a closer examination reveals an intentional commitment to inclusivity, global perspective, and representation of a wide range of cultures and histories.

 

A Global Perspective from the Start

From the outset, Core Knowledge introduces children to stories and traditions from diverse regions around the world. In the early elementary grades, students are exposed to folktales from China, Africa, South America, and Native American communities. These narratives are presented as equally valuable components of the world’s literary heritage and help students see themselves and the broader world reflected in their learning experiences.

In history, students explore ancient civilizations extending well beyond Europe, encompassing Ancient Egypt, Mesopotamia, India, China, and the empires of West Africa. As early as 1st grade, students delve into early American cultures like the Maya Inca, and Aztec. Subsequent grades cover global empires such as the Kingdoms of Africa, feudal Japan, the Dynasties of China, and early Islamic Empires. These lessons emphasize the complexity and achievements of non-Western societies, underlining the shared human narrative.

 

Inclusive Voices in Literature and Speeches

Throughout the curriculum, students engage with the works of authors and poets from a wide range of backgrounds. In addition to classic Western authors, students examine the works of Langston Hughes, Maya Angelou, and a host of other African writers. They explore the speeches of Ida B. Wells, Zitkala-Sa, and Mabel Ping-Hua Lee. This body of work encourages students to engage with diverse perspectives, fostering empathy, curiosity, and critical thinking skills.

 

Science and the Arts for Everyone

In Core Knowledge’s approach to science, there is an emphasis on foundational knowledge alongside vibrant depictions of the contributions of scientists from around the globe. Students learn about historical figures such as George Washington Carver, Mae Jemison, Hypatia of Alexandria, and Ibn al-Haytham, alongside familiar figures like Newton and Darwin, underscoring the global and human nature of scientific discovery.

The curriculum also embraces a diverse exploration of musical styles from West Africa, the Caribbean, and Latin America, as well as visual art traditions from Japan, the Middle East, and Indigenous North American cultures. This approach ensures that students study artists like Diego Rivera, Augusta Savage, and Romare Bearden, reinforcing that creativity and innovation exist in every corner of the world.

 

Addressing Hard Histories and Social Movements

Core Knowledge does not shy away from the complex realities of history. Students engage with lessons on slavery in the United States, the Civil Rights Movement, the Holocaust, apartheid in South Africa, and global human rights efforts. These units are taught with sensitivity and depth, introducing students to the voices and experiences of those who lived through and challenged injustice.

Through these lessons, students gain an understanding of not only of what happened in the past but also of how people have challenged systems, altered societies, and shaped our world.

 

Building Knowledge to Build Equity

Most significantly, Core Knowledge is committed to closing knowledge gaps disproportionately affecting under-resourced students. Offering a content-rich and intentionally sequenced curriculum ensures that all students, regardless of their background, have access to the knowledge that supports reading comprehension, academic achievement, and civic participation.

In addition to being inclusive in what it teaches, Core Knowledge is inclusive in why it teaches it. By exposing students to a diverse foundation of content, from folktales of Ghana to the poetry of Langston Hughes to the scientific advances of ancient Baghdad, it enables all learners to see themselves in their studies while acquiring a deeper understanding of the wider world.

At a time when students require both a strong academic foundation and a sense of global belonging, Core Knowledge fulfills both needs. The Core Knowledge Sequence and its curricula are more than a list of topics; they are thoughtfully designed, inclusive program that empower all students to thrive.

As educators, our mission is to equip students with the tools they need to understand the world and succeed in it. The Core Knowledge approach provides a powerful framework for achieving that goal—building a strong foundation of shared knowledge across subjects, grade levels, and student backgrounds. But implementing Core Knowledge effectively requires more than a sequence or a teacher guide. It demands intentional, ongoing professional learning.

 

Why Professional Learning Is Critical in a Core Knowledge School

1. Ensuring Fidelity of Implementation

Core Knowledge is built on a carefully sequenced and content-rich curriculum. To bring it to life in the classroom, educators need to deeply understand not just what to teach, but why and how to teach it. Professional learning ensures teachers are aligned with the Core Knowledge Sequence and Core Knowledge curricula and can maintain coherence across grade levels and subject areas. This alignment is key to unlocking the cumulative power of knowledge.

 

2. Building Content Knowledge and Pedagogical Confidence

One of the strengths of Core Knowledge is its emphasis on rich, domain-specific content, especially in subjects like history, science, literature, and the arts. But many teachers, particularly in early elementary grades, may not have had deep training in all of these areas. Professional learning helps bridge that gap. It builds teacher confidence, sharpens pedagogical techniques, and fosters a deeper personal understanding of the material. This leads to more engaging and effective instruction.

 

3. Supporting Equity Through Shared Knowledge

Core Knowledge is rooted in the belief that access to broad, foundational knowledge is a matter of equity. When every student, regardless of background, has access to the same rich content, achievement gaps begin to close. However, this vision only becomes a reality when teachers and school leaders have the training to implement the curriculum thoughtfully and inclusively. Professional development supports teaching this broad base of knowledge and helps educators ensure all students are empowered by the curriculum.

 

4. Strengthening Vertical and Horizontal Coherence

Professional learning brings educators together to collaborate across grade levels and subject teams. This collaboration strengthens both vertical alignment (across grades) and horizontal coherence (within a grade), ensuring that knowledge builds logically and meaningfully over time. In Core Knowledge schools, this is especially important because the Sequence is only as powerful as its consistency.

 

5. Creating a Culture of Excellence and Growth

When professional learning is embedded in the life of a Core Knowledge school, it signals a shared commitment to continuous improvement. Teachers feel supported and valued. School leaders model instructional leadership. The entire community rallies around a shared vision: every child deserves access to a well-rounded, content-rich education.

 

What Professional Learning Should Look Like in Core Knowledge Schools

To make a real impact, Core Knowledge professional development should be:

  • Content-rich, helping educators deepen their understanding of the topics they teach.
  • Curriculum-anchored, directly tied to the Core Knowledge Sequence and classroom materials.
  • Practice-based, with modeling, coaching, and reflection opportunities.
  • Collaborative, fostering dialogue among educators about what’s working and where support is needed.

Ongoing and embedded, not one-off workshops, but a sustained part of the school culture.

 

Final Thoughts for Teachers and Leaders

Implementing Core Knowledge is a bold and rewarding endeavor. It challenges us to aim high, to teach with purpose, and to believe that every child is capable of grappling with and mastering rich academic content. But we can’t do it alone. Professional learning is the engine that drives successful Core Knowledge schools.

For teachers, it means entering the classroom every day better equipped to inspire, inform, and elevate student thinking. For leaders, it means creating the structures and supports that make this possible by investing in training, building a professional culture, and aligning systems around the curriculum.

When we grow together, so do our students. And with Core Knowledge as the foundation, there’s no limit to what your school can achieve.

In education, the concepts of “innovation” and a “knowledge-rich curriculum” are often viewed as opposing forces. The debate over fostering flexible thinking and problem-solving skills versus ensuring students have a strong foundation of knowledge is a long standing one. However, the truth is that these two ideas do not have to be mutually exclusive. 

 

Why Knowledge Fuels Innovation 

Knowledge plays a crucial role in driving innovation. Students who are well-versed in literature, history, science, and the arts have a wealth of material to draw from when thinking critically, solving problems, and generating new ideas. Innovation thrives when it is built upon a strong foundation of knowledge and understanding. 

 

Blending Knowledge and Innovation in the Classroom 

There are numerous ways in which schools can integrate a content-rich curriculum with innovative practices to cater to various types of learners: 

  • Literature + Modern Dialogue: Students can adapt classic works into contemporary settings, exploring timeless themes in a modern context. 
  • History Knowledge + Civic Action: Students can use their understanding of historical documents to create podcasts that relate key concepts to current events. 
  • Science Knowledge + Inquiry: Students can engage in hands-on learning by designing sustainable habitats based on scientific knowledge. Art + Design Thinking: Students can create murals that tell stories about their communities by integrating historical art with creativity 
  • Music + Creative Expression: Students can express their own narratives through composing original songs inspired by traditional music. 

 

A Shared Vision for Classical and Contemporary Schools 

This approach not only respects the traditions of classical schools but also provides a practical way for public schools to bridge opportunity gaps and prepare students for a rapidly evolving world. By combining a knowledge-rich curriculum with innovative teaching methods, both types of schools can foster innovative thinking, wisdom, and capability in their students. 

 

Moving Forward 

The key lies in finding a balance between tradition and adaptation. Schools can embrace both their heritage and the need to evolve to meet future demands. Innovation is not about discarding what has proven to be effective but about finding new ways to apply it boldly and creatively. 

Ultimately, the most powerful innovations emerge from minds well-equipped with knowledge, wisdom, and the confidence to think innovatively. By embracing a knowledge-rich, innovation-focused education, schools can empower students to thrive today and, in the years, to come. 

Biographies of Active Scientists and Engineers

The Core Knowledge Foundation is excited to announce an exciting new initiative created to enhance your entire CKScience curriculum. This K-5 suite of units is called Science in Action.

Reading stories about real, living, active young scientists will help students connect science and engineering concepts to real-life situations.

This human-centered approach introduces students to active, young researchers—not only illuminating their professional lives but examining the younger, formative years of each.  Your students will get a glimpse of each scientist’s youth, what they felt like, and what interested them when they were in elementary school, middle school, and high school. These biographies portray real people when they were your students’ ages, bringing to life moments and sparks in their young lives as they became interested in science and engineering.

Science in Action is designed to assist students in recognizing science and engineering concepts from a human perspective. Each person portrayed in Science in Action is currently an active scientist, engineer, or teacher.

Science in Action can be incorporated seamlessly into your existing planning guide.  Each grade-level unit introduces at least two young scientists. Chapters and activities allow for teachers to assign readings in the SIA books either during a special week or may choose to integrate teaching biographies as a sidelight to your core curriculum.

There are three curriculum components to Science in Action (K–5). Each grade level includes a Reader, a complete Teacher Guide, and a wealth of Online Resources.

Each Reader is a student reading book (or to be read aloud in K–2). Each scientist is portrayed in two chapters. The first chapter introduces the scientist as a young person. What was this scientist like in elementary school? What caught their attention? Who influenced them? The second of the two chapters shows the person now, actively engaged in science or engineering research. Then, your students can read about the scientists of the past that most influenced them.

Each Teacher Guide provides a plethora of information to help you communicate to your students about the lives and interests of the scientists. The introduction lays out information on NGSS standards and three-dimensions, Common Core connections, activity pages, materials, and pacing. Each TG includes an activity and answer pages related to the content of the biographies. Teacher guide and prompts are also found throughout the TG.

Online Resources, are keyed with icons in the Teacher Guide, and provide links to outside sources for both curriculum help and extension of concepts via video links.

Introducing Connecting Math to Our World!

The Core Knowledge Foundation is excited to announce an exciting new initiative created to enhance any math program.

Reading stories containing math helps students connect mathematical concepts to real-life situations. Instead of abstract formulas, this program showcases math in action. This approach aims to foster appreciation, not just comprehension, of mathematical principles. This helps to enhance students’ understanding of the importance of math. Reading about how math is used helps students develop math literacy skills such as problem solving, critical thinking, collecting and interpreting data, and communication. 

Connecting Math in Our World is designed to assist students in recognizing mathematical concepts in contexts, fostering a deeper understanding and engagement with the subject. The program’s flexibility allows teachers to seamlessly incorporate these activities into their existing curriculum, enhancing math instruction and creating a more holistic learning experience. The result is a more confident and curious learner, better equipped to view the world through a mathematical lens.

There are two components to Connecting Math to Our World (K-5). Each grade level includes a Student Reader as well as an online Teacher Support document. 

Each chapter in the Student Book focuses on a Core Knowledge Sequence Math Standard and explores its real-world applications. This program is unique in that each chapter functions as a stand-alone activity, which can be used in any order, and covered in as little as 15 minutes. They are engaging and age-appropriate, featuring a mix of fictional stories to nonfiction narratives. Chapters can be used to introduce or review a math concept, or to tie concepts together. Additionally, they enable students to see how math intersects with other subjects, including science, language arts, music, and art. These chapters can increase engagement and develop mathematical vocabulary, all while helping clarify math concepts and make them more meaningful.

Beginning in Grade 3, the Student Reader is designed to be read independently by the students or read together in class, depending on the reading skills of the students.

The online only Teacher Support includes a section for each chapter. Each of these sections contain a preview of the chapter, an introduction to focus student attention, questions and answers that are designed to tease out the math concept, an extension activity, and a statement connecting the math concept to the broader world.

From the Bookshelf—Core Knowledge Free Library is an exciting new initiative that has been created to further support and enhance CK curriculum materials. The library will launch in March 2025 with Voices in History, a highly engaging biography series, and Tales from Latin America and the Caribbean—the first in a series of collections of tales from around the world.

The vision for the website began with Don Hirsch’s desire for the Core Knowledge Foundation to create and provide free access to high quality children’s literature written by acclaimed children’s book authors.

In this early phase of development, 26 diverse Voices in History biography titles have been published. These titles connect to the Core Knowledge Sequence, and to one or more of the following curriculum programs—CKLA, CKHG, CKSci, and the Arts. For example, titles such as Anne Hutchinson: Banished, or Benjamin Franklin: Let the Experiment Be Made, can be used alongside the Grade 3 CKLA Colonial America unit, or the Grade 3 CKHG unit The Thirteen Colonies. In the same way, Abraham Lincoln: Defender of a Nation, and Federico Fernández Cavada: The Spy in the Hot-Air Balloon, can be enjoyed when teaching the Grade 5 CKHG unit about the Civil War. These titles can therefore be integrated into lesson time by reading them aloud, or by using them as a resource for independent reading. The biographies are suitable for strong independent readers aged eight and up.

In addition, it’s important to remember that biographies teach invaluable lessons by providing insight into the lives and events of some of the most extraordinary people who ever lived. We hope you will use this free resource in the classroom.

As well as the biography series, From the Bookshelf also offers beautifully written and illustrated Tales from Latin America and the Caribbean. This title, the first in a new series, was written by children’s book author Silvia López whose writings reflect her interest in animals, history, folklore. The book was illustrated by the talented artist Ivan Pesic.

Tales from Latin America and the Caribbean is an extension of CKLA K-2 units such as Grade K Nursery Rhymes and Fables, Grade K Stories, Grade 1 Fables and Stories, Grade1 Different Lands, Similar Stories, and Grade 2 Fairy Tales and Tall Tales. It can therefore be read aloud in a classroom setting, and later, be used for independent reading as students develop their skills.

From the Bookshelf is an ongoing initiative. More titles will be announced later in 2025. We invite you to explore this exciting new website.

This week is Civic Learning Week. In the words of its founders at iCivics, this week is a time to “highlight the importance of civic education in sustaining and strengthening constitutional democracy in the United States.” This is a mission that we believe in strongly here at Core Knowledge. One important goal of our curriculum is the creation of literate citizens that are able to contribute to a democratic society.

One way we fulfill that mission is through the Pathway to Citizenship, a thread that runs through the Core Knowledge History & Geography (CKHG) units in Grades 3–6. Each American history unit in those grades includes questions, activities, and support notes related to the history, laws, and the structure of the American government. These questions, activities, and notes are identified in the Teacher Guides with an American flag icon.

The Pathway to Citizenship continues in the Core Knowledge middle school U.S. History program. These volumes also include Civics in Action prompts and activities that are intended to encourage students to develop civic awareness and civic participation.

CKHG also includes optional civics units. These units provide student-friendly direct instruction in civic ideals, civic participation, and the history of our political system. These units can be implemented in conjunction with the Core Knowledge Sequence and History & Geography units or used independently. The Grade 1 unit, Lessons in Civics, can be used in Grades K–2. The Grade 4 unit, Understanding Civics, can be used in Grades 3–6. The middle school level curriculum includes Civics and Economics in U.S. History and Civics and Economics in World History. Both can be used in either Grade 7 or Grade 8.

We hope you will join us in our efforts to support and prioritize civic education across the country.

Impact of a Content-Rich Literacy Curriculum on Kindergarteners’ Vocabulary, Listening Comprehension, and Content Knowledge

 

In a recent study, researchers explored the effects of the content-rich literacy curriculum CKLA: Core Knowledge Language Arts on various aspects of kindergarten students’ development. The study focused on evaluating the impact of Core Knowledge Language Arts Knowledge Strand on vocabulary, listening comprehension, and content knowledge among young learners.

 

Research Design and Methodology

The study incorporated findings from two separate randomized controlled trials (RCTs), with the second trial designed as a replication of the first. A total of 47 schools in large urban districts in the United States were randomly selected to either implement the CKLA Knowledge Strand or serve as a waitlist control group. The CKLA Knowledge Strand places a strong emphasis on language comprehension through interactive read-alouds that aim to systematically enhance students’ content knowledge.

 

Implementation and Support

Teachers received two days of professional development workshops to familiarize themselves with the curriculum, in addition to ongoing support from facilitators during the implementation phase. The study involved 1,194 kindergarten students who underwent individual pre- and post-test assessments to measure proximal and standardized vocabulary, listening comprehension, and content knowledge in science and social studies.

 

Key Findings

After approximately one semester of implementing the CKLA Knowledge Strand, researchers observed positive and significant impacts on proximal vocabulary, as well as science and social studies knowledge among the students. Furthermore, the study revealed significant interactions between vocabulary and content knowledge, indicating that children with higher receptive vocabulary at the beginning of the school year derived greater benefits from the curriculum in terms of learning new words and content knowledge.

 

Significance of Study

This research adds a novel perspective by examining the influence of a content-rich literacy curriculum that integrates literacy and content-area instruction. The replication of positive effects across the two RCTs highlights the robustness of the findings and underscores the potential benefits of such educational approaches for young learners.

This study sheds light on the importance of incorporating content-rich literacy practices in early education to enhance students’ language comprehension, vocabulary acquisition, and content knowledge. The integration of literacy and subject-area instruction can offer a holistic learning experience and contribute to the overall academic development of young learners.
