Arizona Approves 95 Percent Group’s Phonics Lesson Library ESSA Evidence

AZ approves PLL

It is well known that reading difficulties can pose major barriers to academic success. Schools need evidence-based, effective tools to support their early readers.

LXD Research recently led a year-long efficacy evaluation of the Phonics Lesson Library paired with the Phonics Chip Kits for 95 Percent Group LLC which was approved by the Arizona Department of Education as an early literacy intervention. This approval joins the prior approval of the 95 Phonics Core ProgramTM (95PCP) and the Phonological Awareness (PA) Lessons Deluxe Package (PA Lessons) for a total of four approved products. These foundational reading products that fit in with a district’s current literacy toolkit now have state-reviewed efficacy research to meet ESSA Tier 1-3 evidence.

LXD Research served as an independent evaluator and was able to support 95 Percent Group in establishing evidence that their products met ESSA evidence criteria as part of the Arizona DOE Move On When Reading initiative (see the products listed here). 

The LXD Research team also conducted a full-year study of the Phonics Lesson Library, used in conjunction with the Phonics Chip Kit, that met ESSA Tier 2 criteria. Students were also tested with the Phonics Screener for InterventionTM (PSI) every three weeks to target daily small-group instruction. The selection design paired schools and grades in a California district based on a variety of school-based characteristics to find similar groups of students who would either use the 95 Percent Group suite or teach early literacy as usual. Schools using the Phonics Lesson Library intervention model saw significant gains above the comparison schools in student reading scores. LXD Research designed a report brief with a summary of the results (PLL Brief) to disseminate these research findings.
