21 Houston ISD schools receive failing grades in new report from the Texas Education Agency

The rankings mark the first time the TEA assigned letter grades to individual schools across the Greater Houston area, and the state. Under a new state mandate, the grades could determine if some of HISD’s long-struggling schools should be shut down, or if its locally-elected school board should be replaced by the state.

On a district-wide level, more than 25 percent of 90 local districts were given A grades, 46.6 percent received B’s, more than 15 percent were C’s, about 6.6 percent earned D’s and 4.4 percent were rated as F, the Chronicle reported.
