Using data from students in Grades 3-8 in school years 2018-2019 (N = 1,871) and 2021-2022 (N = 1,740), we examined the strength of fall math screening using Measures of Academic Progress (MAP) for predicting end-of-year state math assessment performance levels and whether this prediction varied across English language proficiency (ELP). In addition, we examined whether differential predictive strength varied across screenings using English or Spanish MAP math (2018-2019 only). MAP math was similarly predictive across the ELP continuum (odds ratios between 6 and 15; log-odds between 1.5 and 2.5). However, in 2018-2019, there was more variation in screening prediction across ELP for students assessed using the English MAP math compared to Spanish MAP math. For 2021-2022, there was little evidence of differential screening prediction across ELP. Our findings suggest that MAP math is moderately predictive across ELP and school years. We discuss limitations, future directions, and implications for research and practice.
