AUSTIN, Texas (AP) - Texas Education Commissioner Robert Scott is set to release much-anticipated school rankings.

The results are to be announced at 1 p.m. Friday.

Schools are rated based on student performance on the Texas Assessment of Knowledge and Skills and a standardized test for special education students along with dropout and completion rates.

Last year, more than 370 districts were ranked either exemplary or recognized, the highest rankings available under the state's accountability system. The number of school districts receiving the lowest ranking, academically unacceptable, was 37, mostly attributed to students' scores on the math and science portions of the TAKS.
