Texas school districts using the state-developed Bluebonnet Learning curriculum saw slightly better year-over-year achievement last school year than other districts, according to Texas Education Agency data released Sept. 30.
What's happening: During the 2025-26 school year, 619 of Texas' roughly 1,200 public school districts opted in to implement at least one of the three Bluebonnet curriculum programs—elementary math, secondary math and elementary language arts.
On this spring's State of Texas Assessments of Academic Readiness exam, districts using the state-developed math materials saw student improvement that was 0.6 percentage points higher than students in other districts, while districts that implemented the reading materials performed 0.2 percentage points higher on the STAAR than other schools.
What they're saying: The TEA said the gains in student achievement an "encouraging sign of early progress."
Zeph Capo, president of the Texas American Federation of Teachers, a statewide educator union, disagreed, calling the results "rather paltry."
"It may take a few more years to determine if this is a valid trend or simply an anomaly," Capo said in a statement.
