Conducted by WestEd in partnership with the Silicon Valley Education Foundation’s STEM Innovation Hub (iHub) team and supported by the Bill & Melinda Gates Foundation, this independently funded quasi-experimental study that meets Every Student Succeeds Act (ESSA) Level 2 criteria found that Grade 7 students who spent a minimum of 45 minutes a week or more on i-Ready for Mathematics during the 2017–2018 school year demonstrated a significant improvement in their scores on the Smarter Balanced Assessment (SBA) over students who did not. Specifically, utilizing data from more than 1,700 students, WestEd found that students using i-Ready for more than 45 minutes tended to score 24 points higher than similar students who used i-Ready for less than 45 minutes. Students with 45 minutes or more in i-Ready also experienced greater growth toward the next achievement level on the SBA.
