Idaho Standards Achievement Test 2020-21 Predictability Study

This document is a research report detailing the ISAT 2020-21 Predictability Study conducted by the Center for Research and Reform in Education (CRRE) at Johns Hopkins University. The study aimed to evaluate the effectiveness of the Istation Indicators of Progress (ISIP) Early Reading program in Idaho, particularly in light of instructional changes due to the COVID-19 pandemic. The research focused on the correlation between ISIP scores and ISAT ELA proficiency levels for Grades 3-5 students during the 2020-21 school year. The report outlines the methodology, including correlational analyses and multinomial logistic regression, to assess the relationship between fall and spring ISIP scores and spring ISAT proficiency levels. Key findings indicate a strong association between ISIP scores and ISAT ELA scores, with specific probabilities of achieving different ISAT proficiency levels based on ISIP scores. The report also discusses participant demographics, measures used, and limitations of the study.
