Summary:

Kirby School District 140 includes seven schools serving preschool through grade 8: five elementary schools and two middle schools. In 2025–26, the schools’ average all-grades results were 72% in ELA and 58% in math, compared with statewide results of 56% and 40%. Results varied from school to school, but every school was above the state in both subjects. The clearest overall takeaway is that the schools collectively performed well above state results in both ELA and math.

Virgil I Grissom Middle School led all seven schools in ELA at 77%, while Millennium Elementary School led in math at 62%. Within their grade spans, Grissom topped the other middle school by 7 percentage points in ELA and 4 in math; Millennium led elementary schools by 3 points in ELA and 1 in math. At the lower end, Helen Keller Elementary School had the lowest all-grades ELA result at 68%, and Christa McAuliffe School had the lowest math result at 52%. Grade-level results add important nuance: Helen Keller led elementary schools in third-grade math at 78%, but had the lowest fourth-grade math result at 45%.

ELA improved at all seven schools from 2024–25 to 2025–26, and the group average rose by 9 percentage points; math was nearly flat overall, despite a 16-point gain at Helen Keller and declines at Millennium and Fernway Park Elementary School. SchoolDigger gives the district 4 stars and ranks it 188th of 738; its 2025–26 rankings place Grissom in the 84th percentile and Millennium in the 81st. Practical differences may also matter when comparing schools: student–teacher ratios range from 11.7:1 to 15.6:1, and the free/reduced lunch eligible measure for 2021–22 ranged from 10% at Millennium to 20% at Fernway. Those measures describe school context, not the cause of results.
