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

Twenty-one Houston ISD schools, roughly 7.5 percent of the entire district, did not meet state standards and received a failing grade in a new report released Thursday by 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.

Grades are assigned based on a school's scaled score in three different categories: raw student achievement, student progress and performance relative to percentages of economically disadvantaged students, which altogether accounts for 70 percent of the rating. The remaining 30 percent is based on how schools and districts close achievement gaps between different groups of students.

The scale scores are based on 2018-19 State of Texas Assessments of Academic Readiness, or STAAR, tests at the elementary and middle school levels. For high schools, scale scores are measured using test scores, graduation rates and college readiness metrics.

For some of the failing HISD schools, a new state law mandate could mean a failing grade will either close down the school, or lead to changes on the board. Wheatley High School failed to meet state academic standards for an seventh consecutive time, the Chronicle reported.
