Summary
C C Mason Elementary is a mid-sized school in Cedar Park, TX, serving 691 students from Pre-Kindergarten through 5th grade as part of the highly-rated Leander Independent School District (Isd). This school has shown a clear upward trend over the past decade, rising from the 39th percentile in 2016 to a solid 68th percentile in 2026, though it has recently plateaued after a peak in 2023. C C Mason sits in a diverse neighborhood with a wide range of school performances nearby, from top-tier schools like Deer Creek Elementary (96th percentile) and Basis Cedar Park Pri (100th percentile) to lower-performing neighbors like Lois F Giddens Elementary (19th percentile) and Patricia Knowles Elementary (16th percentile), making it a middle-ground performer in a neighborhood with extreme highs and lows.
The school's biggest strength is in Reading, where scores are generally on par with or slightly above the district average, and it shows a remarkable ability to support its English Language Learner students, ranking in the 82nd and 84th percentiles in recent years. However, C C Mason has a persistent and significant weakness in Mathematics, with scores consistently below the district average across all tested grades—for example, 5th-grade Math proficiency was just 41.13% compared to the district's 50.66% and the state's 47.38% in 2025-2026. Science is another critical weak point, with only 20.59% of 5th graders proficient in 2024-2025, well below the district and state averages. The school also struggles profoundly with its low-income students, ranking in the 11th percentile for this subgroup, which is the school's weakest area and a major concern for families.
On a positive note, C C Mason has shown significant improvement in serving its Special Education students, jumping from the 29th percentile in 2023-2024 to the 64th percentile in 2025-2026, suggesting recent interventions are working. The school's future success hinges on closing the math and science gaps and addressing the achievement disparity for economically disadvantaged students. With a higher free/reduced lunch rate (16.06%) than top performers like Deer Creek (8.46%), C C Mason's attendance zone likely includes a more economically diverse population, which directly impacts its overall metrics. For parents, this school offers a strong foundation in reading and support for English learners, but requires attention to math, science, and support for low-income students to reach its full potential.
