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.
