Top-ranked DeKalb schools not so great on growth

Some well-regarded DeKalb County schools posted average performances based on Georgia’s new “student growth model,” which measures how much students learn in a year compared with peers across the state.

The results are derived from year-to-year performance on Georgia’s Criterion Referenced Competency Tests and End of Course Tests and are for the 2012-13 school year. Change in a student’s test performance is compared against that of peers who had similar scores in the prior year.

DeKalb’s Wadsworth Magnet School for High Achievers lived up to its name in fourth- and fifth-grade math and in fifth-grade reading, with a 100 percent pass rate on the CRCT. However, when compared to peers across Georgia, students at the school registered modest growth: 35 percent in fourth-grade math, 43 percent in fifth-grade math and 46 percent in fifth-grade reading. The median growth percentage gives parents a new way to assess the performance of their school, says the Georgia Department of Education.
