The next chapter in the Science of Reading
Introducing ¼â½ÐÊÓƵapp CKLA 3rd Edition, a K–5 core literacy program within ¼â½ÐÊÓƵapp’s literacy suite. For more than a decade, ¼â½ÐÊÓƵapp CKLA has transformed classrooms nationwide with its intentional knowledge building and systematic skills instruction. Available for the 2025–2026 school year, the 3rd Edition builds on this successful foundation to better support all ¼â½ÐÊÓƵapp in becoming confident readers, writers, and thinkers. Together, let’s write the next chapter in the Science of Reading.
¼â½ÐÊÓƵapp CKLA serves
Our approach
Improve outcomes with a program built on a decade of research, and that meets the strongest ESSA Tier I criteria.
Grounded in the Science of Reading
As the original Science of Reading program, ¼â½ÐÊÓƵapp 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
¼â½ÐÊÓƵapp 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 ¼â½ÐÊÓƵapp 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 ¼â½ÐÊÓƵapp simultaneously strengthen their communication skills, comprehension, and confidence.
High-quality, diverse texts
¼â½ÐÊÓƵapp CKLA ¼â½ÐÊÓƵapp 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 ¼â½ÐÊÓƵapp 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.
