Maps


This map displays Empirical Bayes estimates of district level average achievement. These are centered around zero, so a score of zero means the district is at the average expected level of achievement within the United States. One-unit below zero means that students in the district are one grade level behind the average; one-unit above zero means that students in the district are one grade level above the average. A one-unit change is interpreted as a grade-equivalent change, such as the difference in achievement between grades 3 and 4.

This map displays Empirical Bayes estimates of district level changes in average achievement across grades. An estimate of 1 means that students in the district are increasing by 1 grade equivalent unit per grade. Estimates below 1 mean that students in the district are increasing in achievement less than one grade level per year, and estimates greater than 1 indicate that students in the district are increasing in achievement greater than one grade level per year.
