NOTES: The figures in bold in the upper panel are those most relevant for each cohort. Proficiency rates were calculated based on a composite measure of reading and mathematics rates. The rates were calculated for each DCPS school, and the schools were sorted by rate. The proficiency rate for the school that was the "25th percentile" school in the distribution became the cut-point for the lowest quartile. The rates for the schools at the 50th and 75th percentiles became the cut-points for the second, third, and highest quartiles. As context for interpreting this distribution, schools that fell in the two lowest quartiles had fewer than 44 percent of their students achieving proficiency on the DCPS assessment.
