The next chapter in the Science of Reading
Introducing ĵֱ CKLA 3rd Edition, a K–5 core literacy program within ĵֱ’s literacy suite. For more than a decade, ĵֱ CKLA has transformed classrooms nationwide with its intentional knowledge building and systematic skills instruction. The 3rd Edition builds on this successful foundation to better meet the needs of all students and help them become confident readers, writers, and thinkers. Together, let’s write the next chapter in the Science of Reading.

Grounded in the Science of Reading
As the original Science of Reading program, ĵֱ CKLA puts research into action with explicit, systematic foundational skills instruction and a proven knowledge-building sequence. In collaboration with education experts and practitioners, we provide powerful resources that deliver real results.
Background knowledge drives results
ĵֱ CKLA follows the Core Knowledge Sequence, a content-specific, cumulative, and coherent approach to knowledge building. This approach improves reading scores and closes achievement gaps by establishing a robust knowledge base that strengthens comprehension.
In ĵֱ CKLA 3rd Edition, we’ve enriched our Knowledge Sequence with a wider range of perspectives and high-quality texts in new and enhanced units.

Build foundational skills for long-term success.
Students progress from simple to complex skill development starting with phonological and phonemic awareness. Instruction in Grades K–2 explicitly teaches the 150 spellings for the 44 sounds of English, following an intentional progression to ensure student success.
In our 3rd Edition, we’ve added dedicated Grade 3 foundational skills instruction that can either support core lessons or function as an intervention, based on student needs.
Daily writing deepens learning.
Grounded in the Science of Writing—the research on how kids learn to write—instruction is explicit, daily, and woven into the curriculum’s rich content. It covers both transcription (handwriting and spelling) and composition (organizing ideas into narratives) with high-impact activities like sentence-level combining and expanding, and pre-writing exercises. Writing and reading instruction are integrated so students simultaneously strengthen their communication skills, comprehension, and confidence.

High-quality, diverse texts
ĵֱ CKLA students are immersed in a variety of texts—complex read-alouds, decodable chapter books, trade books, and content-rich readers—that reflect varied experiences and connect to learning goals.
Readers are 100% decodable for Grades K–2, empowering students to directly apply what they’ve learned. Novel Study units for Grades 3–5 offer a mix of contemporary and classic literature, and Culminating Research Units in every grade include a set of authentic texts and trade books.
Reach all learners with differentiated support.
Scaffolds and challenges developed in collaboration with education experts make content accessible to every student, including multilingual and English learners. With strategies embedded right in the curriculum, teachers can deliver in-the-moment, individualized instruction to meet diverse student needs.
