Here's some information about the test from the article:
English-language arts goes through grade 10 standards. The mathematics portion is a little bit of grade six standards and a lot of grade seven standards, and there are 12 Algebra I questions out of 80 total questions that students are scored on in math....
Students have to get 55 percent correct on the math part of the test and 60 percent correct on the English-language arts part of the test to pass each of those portions.
I don't understand the argument that a diploma should be given for 12 or 13 years of seat time. Why should one be given if students cannot pass a test to these minimal standards?
