Efficacy Studies
Trust in literacy solutions that have been proven effective. Designed with guidance from the Every Student Succeeds Act (ESSA), our efficacy studies meet the highest levels of evidence.
95 Phonics Core Program® efficacy study
A year-long study of 95 Phonics Core Program conducted in Missouri demonstrated that students who used the program outperformed those in all grades K-2 who did not use the program. Results support ESSA Level 1 evidence for product effectiveness across these grade levels.
The data show a positive, significant impact on student Acadience scores for all grades (K-2) on multiple subtests, as well as on composite scores for kindergarten and grade 2.
95 Phonics Lesson Library® efficacy study
Intervention students using 95 Phonics Lesson Library showed higher gains on the CORE Phonics Survey and Acadience Reading than the comparison group in first grade on multiple measures.
One95 Literacy Ecosystem grades K-1 efficacy study
National reporting on the opportunity gap from before the pandemic to fall 2021 showed a slight dip in students across the country reading on grade level. For Wicomico County Public Schools, the loss was two to three times greater. The district needed to bring transformational change to their reading instruction.
One95 Literacy Ecosystem grades 2-3 efficacy study
Wicomico County Public School students using One95 Literacy Ecosystem products in year 2 saw higher gains than students in year 1 (8% to 35% in Grade 2, and 9% to 29% in Grade 3). In year two, the percentage of students on or above benchmark more than doubled from fall to spring using the 95 Phonics Core Program. Read more below.
Educators see results
“Five months into implementation, I got a message from a teacher that said, ‘My 95 PCP assessment data was at 63 percent mastery for assessment one. And now, at assessment three, my students are at 92 percent mastery.’ Our goal is 95 percent mastery and we have three months of school left!”–Jen Burton, Director of Literacy, Fulton County Schools
95 Phonics Chip Kit™ efficacy study
The treatment school outperformed the comparison school in both grades in 2021–2022. Over the two years, the effect size of the 95 Percent Group portfolio (treatment) group was double that of the comparison group.
95 Teaching Blending™ efficacy report
Students who read whole words blended without subvocalizing will score higher starting in the middle of first grade, and Common Core standards reflect that expectation.

95 Multisyllable Routine™ Cards efficacy study
Students in year two saw higher gains than students in year one by simply adding Multisyllable Routine Cards to daily instruction. Gains made by students below grade level using MSRC resulted in meaningful increases in students working on or above grade level by spring.
95 Phonemic Awareness Lessons Deluxe™ efficacy study
Students using 95 Phonemic Awareness Lessons showed higher gains on Acadience Reading than the comparison group on multiple measures in kindergarten, earning the product a listing on Evidence for ESSA.
95 Comprehension Grades 3-6 efficacy study
The research is very clear on what good readers do to make meaning out of text.
