10r is similar to remedial (I forget the correct term). They were housed at Demerest aka the "alternative school". By state law every student is required to take the 11th grade test. Under Raia (and before) these students were excluded from the tests. This ginned the test scores up higher than they would have been.

Scott,

I want to learn more about 'the 10r issue.

First what does 10r mean?
How can you tell that the 10rs are not included in the stats?
