[quote=Anonymous][quote=Anonymous]Are all HSs pushed down 1 rating because they need to make TJ a 10 and need to differentiate between TJ and everything else? It's more like a state ranking/tiers right, instead of true rating. Which is why you can't compare across states. [/quote] The great schools rankings are based on a state-wide comparison. It is not a ranking within a district. So, there could be many 10's in one district or just one 10 or none at all. And you are right -- you can't really compare across state lines b/c the tests are generally different (unless you are comparing two common core schools -- you still couldn't compare the GS rating, but you could compare the actual pass rates). Here's what GS says: In states with only data on test scores In states where only student achievement is used to calculate ratings, the overall GreatSchools Rating is an average of how well students at a given school do on each grade and subject test. For each test, ratings are assigned based on how well students perform relative to all other students in the state, and these ratings are averaged into an overall rating of 1 to 10. The distribution of the GreatSchools Rating in a given state looks like a bell curve, with higher numbers of schools getting ratings in the “average” category, and fewer schools getting ratings in the “above average” or “below average” categories.[/quote]
