|GreatSchools Ratings for Delaware|
In calculating these ratings, GreatSchools analyzed the 2008-2009 Delaware Student Testing Program (DSTP) reading, writing, math, science and social studies results and compared them to the test results for all Delaware schools with the same grade levels. Grades 6, 7, 9, 10 and 11 did not receive ratings because there were fewer than 50 schools with scores for those grades.
If there are no GreatSchools Ratings for a school, the school's test results were either not reported or incomplete. The different student groups are identified by the Delaware Department of Education. If there are fewer than 15 students in a particular group in a school, the state doesn't report data for that group.
Keep in mind that when comparing schools using GreatSchools Ratings, it's important to factor in other information, including the quality of each school's teachers, the school culture, special programs, etc.
GreatSchools Ratings cannot be compared across states, because of differences in the states' standardized testing programs.
