|GreatSchools Ratings for Idaho|
In calculating these ratings, GreatSchools analyzed the spring 2011 Idaho Standards Achievement Test (ISAT) reading, language usage, math and science results and compared them to the ISAT results for all Idaho 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 the Idaho 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.
