LXD Research analyzed data from 462 students in first grade who were Below or Well Below Benchmark at the beginning of the year and participated in using the Phonics Lesson Library and the Phonics Chip Kit as an intervention in CA for the 2021-2022 school year. The product is a Tier 2 or Tier 3 phonics intervention using lessons and manipulatives that support skill development along the Phonics Continuum. The demographic breakdown of this sample included 82% Hispanic students, 33% ELL students, 4% SPED students, and 5% Foster or Homeless students. Students using the Phonics Lesson Library and Phonics Chip Kit during targeted, small group, 30-minute daily explicit and systematic phonics instruction showed higher gains on the CORE Phonics Survey and Acadience Reading than the comparison group. The significance of the findings and the rigorous study design support the Phonics Lesson Library and Phonics Chip Kit as programs that meet the criteria for ESSA Level 2.
