About the Study

In this comprehensive study, EPS partnered with LXD Research, a third-party research company, to examine the relationship between the usage of S.P.I.R.E. and student literacy achievement at Martin County School District in Florida across grades 3–5 during the 2022–2023 school year. Researchers examined this relationship while controlling for grade, race, ethnicity, gender, English Language Learner (ELL) status, and Fall FAST (Florida’s standardized assessment) scale scores.


For all grades, students who completed more S.P.I.R.E. levels had higher spring standardized assessment achievement. These were statistically significant relationships (t(190) = 2.9, p < .01, Cohen’s d effect size = .44) for students across Grades 3–5.

ESSA Evidence Level: Promising (Level/Tier 3)

This study provides results to satisfy ESSA evidence requirements for Level/Tier 3 (Promising Evidence) given the study’s well implemented correlational design and positive, statistically significant findings.


This treatment-only study occurred during the 2022–23 school year and included 192 grades 3–5 students from 13 elementary schools who use S.P.I.R.E. According to demographic data provided by the district, 47% of students were described as Hispanic. Females made up 35% of the group, while males accounted for 65%. In addition, 34% of students were identified as having Limited English Proficiency (LEP). All students were classified as Special Education (SPED).

Study Design and Procedure

Researchers conducted correlations and analyses of covariance to examine the relationship between S.P.I.R.E. usage and student literacy achievement while controlling for grade, race, ethnicity, gender, English Language Learner (ELL) status, and Fall FAST scale scores. This study included the students’ 2022–2023 S.P.I.R.E. progress levels and their standardized assessments (Fall ‘22 as pre-test and Spring ‘23 as post-test) as measures to provide insights into S.P.I.R.E. implementation and evidence about the potential impacts of S.P.I.R.E. on student outcomes.
