Subclaims¶

q2 i? Because the students tested in fall 2020 differed systematically demographically from typical testing populations, the measured impacts of COVID-19 on achievement for the most vulnerable students may be underestimated. → Megan Kuhfeld 2020

Authors' interpretive caution drawn from their analysis of fall 2020 MAP Growth data: "Systematic demographic differences in available assessment data" suggest the measured impacts for the most vulnerable students may be underestimated. This is an interpretation, not a separately tested estimate.

"Systematic demographic differences in available assessment data suggest the impacts of COVID-19 on achievement for the most vulnerable students may be underestimated."

Discussion¶

Related Claims¶

• Approximately one in four students who tested the prior year were missing from fall 2020 data, disproportionately Black or Latinx students in higher-poverty schools, so prior estimates likely understated pandemic impacts — possibly the same claim (merge candidate)
• Systematic attrition differences mean COVID-19 impacts on student achievement are likely underestimated in fall 2020 MAP Growth results — possibly the same claim (merge candidate)
• Longitudinal growth observed for current ELs likely underestimates total-cohort growth because students who reach English proficiency exit and are no longer assessed — related
• Students who did not retest in fall 2020 were disproportionately minoritized and lower-achieving compared with students who retested — possibly the same claim (merge candidate)
• Attrition was concentrated in schools with higher concentrations of racial/ethnic minorities and socioeconomically disadvantaged students — possibly the same claim (merge candidate)
• The dashboard's cohort view restricts results to students who consistently tested across selected terms, and those outcomes may be positively biased — related
• The dashboard's cross-sectional view compares same-grade students across terms using the full sample of testers, but attrition is not random — related
