|GreatSchools Rating for South Carolina|
In calculating these ratings, GreatSchools analyzed the 2010-2011 Palmetto Assessment of State Standards (PASS) writing, English/language arts, math, science and social studies results and the 2010-2011 High School Assessment Program (HSAP) English/language arts and math results for the school and compared them to the test results for all South Carolina schools with the same grade levels.
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 South Carolina Department of Education. If there are fewer than 10 students in a particular group in a school, the state doesn't report data for that group.
Keep in mind that when comparing schools through 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.
