The Core Knowledge Foundation is committed to ensuring that people of all abilities are able to access and use the resources on our website. After nearly a year of working through a wide range of web accessibility updates, we would like to provide you with an update on our progress. While we will continue to improve our website in terms of accessibility, the Core Knowledge Foundation website is now compliant with the latest guidelines for web accessibility.
Working Toward Our Mission

The decision to prioritize updates to improve the accessibility of our website was an easy one for our team to make. An accessible website brings us closer to our mission of advancing excellence and equity in education for all children.
“To achieve this mission, we offer detailed curricular guidance and materials to schools, teachers, parents, and policy makers—to anyone who believes, as we do, that every child in a diverse democracy deserves access to enabling knowledge.”
Now, our free downloadable curricular guidance and materials are accessible to everyone—all educators, parents, policy makers, and others—who can put it into action.
We offer many of our curriculum materials and other resources available for free download on our website, but without an accessible website, finding and downloading resources presented a variety of frustrations for our website users with disabilities. Now, educators and community members of all abilities can use our website to easily access those materials and resources as intended.
About Website Accessibility

An accessible website is a website that anyone and everyone can use as it’s meant to be used.
For a website to be truly accessible, this needs to carry across all of the features that are built into the website, such as our repository of free downloadable curriculum materials and online bookstore. Website accessibility takes a range of disabilities that can affect how people use the web into account, such as auditory, visual, physical and cognitive disabilities.
Web Content Accessibility Guidelines

The Web Content Accessibility Guidelines (WCAG) are the international standard for website accessibility and are the guidelines that we’ve used to update our website. The Core Knowledge Foundation website is now built to be compliant with WCAG version 2.1 AA, the most recent version of accessibility recommendations as of the time of this publication.
Among the many updates we’ve implemented to improve website accessibility include:
- Updating font colors to improve contrast with the background, making it easier for those with visual impairments to read content throughout the website.
- Including a “focus” state for every interactive element on each page, allowing those who can’t use a mouse to engage with the entire website using only a keyboard.
- Improving the HTML structure of the website so those using a screen reader can efficiently navigate the website to find the content that’s most valuable to them.
- Adding additional text context to images so those who may not be able to see them can still understand their purpose.
- And setting the default website language as English programmatically so screen readers use the appropriate pronunciation.
We at the Foundation are thrilled to share this progress with our network, but we also understand that website accessibility requires an ongoing commitment. With the help of our community, we will continue working to ensure our website is accessible for all people and that anyone who shares our mission is able to access the tools and resources they need to join us in advancing excellence and equity in education for all children.

If you have questions about website accessibility or feedback to share about using the Core Knowledge Foundation website or materials personally, we encourage you to reach out to our team. We’ll continue to make updates to our website to give each member of our Core Knowledge community the best experience possible.

This year, as schools are tasked with changing their modes of instruction delivery from face to face to a virtual or hybrid model, electronic books (“e-books”) can offer students unique experiences with texts. In some cases the e-book simply serves as a digital version of a curriculum text or trade book that students can access on a tablet at school or at home. In other situations, the e-books afford interactivity, such as links to vetted websites. Some e-books even have the ability to provide students with access to a text that otherwise would be beyond their grasp due to a language barrier or disability. The Core Knowledge Foundation accepted the challenge to create the option of an e-book format for our Core Knowledge History and Geography (CKHG) and Core Knowledge Science (CKSci) Student Readers, as well as Core Classics for our schools. When designing the Core Knowledge Library of Student Reader e-books in Partnership with Fathom Reads, we set out to offer students all of the options listed above and much more.
For children who struggle with reading grade-level texts, or for those with visual impairments, e-books with audio supports can provide access to text content. The e-books in the Core Knowledge Library e-booknot only offer students the ability to listen to the pronunciation of select words, they also provide students the option of hearing the entire story read aloud. Students can also prompt the e-books to read aloud the vocabulary and questions in the callouts.
The Core Knowledge Library e-books provide students the option of reading (or listening) to the text in either English or Spanish. Offering Spanish-speaking students the opportunity to access the history and geography content through their native language serves as a crucial step in building their knowledge base around a topic.
Adding interactivity to e-books transforms the experience with the text from passive to active. This can include embedded interactive content or links to outside sites that provide students with a closer look at a particular event or concept. The Core Knowledge Library of e-books are filled with interactive opportunities for the reader. Whether its third graders exploring a photo gallery of Native American pottery, fourth graders listening to the poem “The Midnight Ride of Paul Revere” by Henry Wadsworth Longfellow, or fifth graders “experiencing” the start of the Civil War at Fort Sumter via video simulation, the supplemental activities made available through the e-books deepen students’ engagement with text content.
While e-books can be used as part of the core instruction, if they incorporate a wide range of functionality they can serve as effective independent instructional tools. Since our initial release of ten CKHG American History titles in October of 2019, teachers and parents report that some of the ways they use the Core Knowledge interactive e-books include: as part of listening centers for students to review a previously taught chapter, for struggling readers as added support, as homework for additional exposures to the text and content, and even used in Zoom whole class discussions.
Core Knowledge Mathematics™ is the newest subject-area to be added to the Core Knowledge Curriculum Series™, with our immediate focus on the middle grades in 6–8. Based upon the highly-rated Illustrative Math and Open Up Resources OER curriculum, CKMath offers students the opportunity to develop conceptual understanding and procedural fluency while they work with an adult to apply math in the real world. Comprehensive Teacher Guides support educators in orchestrating productive mathematical discussions and ensuring mathematical success for all students. Available now:
