|GreatSchools Ratings for Oregon|
In calculating these ratings, GreatSchools analyzed the 2009-2010 Oregon Assessment of Knowledge and Skills (OAKS) reading, writing, math and science results and compared them to the test results for all Oregon 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.
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.
