Texas Education Agency gave Castleberry High School a B, 85 out of 100, in the question of "How much better did the students perform at this school?" School Progress measures how much better students performed on the STAAR test this year versus last year. It also looks at how much better students are doing academically at the school compared to similar schools. High schools, Castleberry High School as an example, earned a B (80–89) for recognized progress in 70% or more of students making a year's worth of academic gains OR the district's achievement is above average compared to similar districts.[5]

Calculating the score comes in hand of two components, "Academic Growth" and "Relative Performance." Academic Growth measures how many students gained a year in reading and math skills over the course of the school year. A full or half-point is given for each student who grew academically, depending upon how much growth occurred. The resulting point total is generally equivalent to the percentage of students who gained a full year of academic skills, and the point total is converted to a final score. In this way, growth is rewarded, even if students start significantly below grade level. Castleberry High School scored an 80 out of 100. Students who grew a year academically was at 70%, compared to the district's average of 66%.[6] Relative performance is determined by looking at a school's performance in the Student Achievement domain relative to the percentage of economically disadvantaged students at the school.[6] Using data from 2016–17, every school in Texas was plotted with its Student Achievement vs its students' poverty, to establish a baseline for this comparison. Schools with Student Achievement above the achievement at schools with similar levels of student poverty receive higher scores. Castleberry High School scored an 85 out of 100. Student Performance and CMM Readiness was noted at 55% and economically disadvantaged students at 77.1% (range: 77.1 to 78).[6]
