The first study looked at standardized test scores, while the second compared schools with similar demographic profiles.
In total, 135 schools were identified as better-than-expected performers — 20 of which were recognized by both studies, according to the state Department of Education.
Jeffers Elementary School was one such school. According to data from 2010 released by the state, 18 percent of Jeffers’ 398 students are economically disadvantaged, 12 percent are disabled and 5 percent are minorities. These percentages are similar to the comparison group average.
Data from the 2010 Michigan Educational Assessment Program exam shows that 99 percent of Jeffers students are proficient in math and reading, and 81 percent are proficient in writing. Writing scores are 19-percent higher than the comparison group average of 62 percent.
Mary A. White Elementary School Principal Val Livingston said she was surprised to find out that her school had been identified by the first study.
