CKLA flipbook cover_gr2b, an independent nonprofit organization that seeks to improve K-12 education by providing detailed reviews of instructional materials, has released its first round of reviews of English Language Arts (ELA) curriculum materials for Grades K-2. Among the six programs analyzed in this first round of reviews, two meet all criteria for alignment and usability in all grades—ReadyGEN from Pearson, and our own Core Knowledge Language Arts™! enlists teams of educator reviewers to analyze materials based on clearly defined criteria grouped as three “gateways”:

  1. Text Quality & Complexity and Alignment to Standards Components
  2. Building Knowledge with Texts, Vocabulary, and Tasks
  3. Usability

In its summary of findings on CKLA for grades K-2, notes that “the instructional materials . . . meet expectations for all criteria across Gateways 1, 2, and 3.” also notes that:

  • For grades K-2, CKLA materials “include strong foundational skills to support young students’ reading development as they move from learning how to read to comprehending complex texts.”
  • CKLA Teacher Guides provide “explicit and comprehensive” support.
  • CKLA texts for K-2 “are rich and rigorous, offering students a balance of informational and literary reading.”
  • The texts “are organized to support students’ building knowledge of different topics,” with plentiful “opportunities for students to analyze ideas and grow their vocabulary.”
  • The program’s design allows for “effective lesson structure and pacing,” and teachers are provided “strategies for meeting the needs of a range of learners.”

In a separate study conducted earlier this year, found that CKLA for grades 3-5 met all criteria for text quality, building knowledge, and usability. For the complete report on CKLA for grades K-5, visit

A comprehensive program for teaching skills in reading, writing, listening, and speaking, CKLA also builds students’ knowledge and vocabulary in literature, history, geography, and science.
