Summary
Idea Walzem Academy is a K-5 charter school in San Antonio, TX, serving 611 students in a high-poverty community where over 85% of students qualify for free or reduced lunch. This school, part of the Idea Public Schools district, has experienced a dramatic and alarming decline in recent years. Once a solid performer ranking in the 59th percentile statewide in 2021-2022, it has plummeted to the 3rd percentile in 2025-2026, earning zero stars. This steep drop is the most severe among nearby schools, including Mary Lou Hartman, which serves a similar demographic but has remained more stable and now outperforms Idea Walzem in every grade and subject.
The school’s academic struggles are most pronounced in mathematics, where proficiency rates are critically low. For example, only 15.7% of 4th graders were proficient in math in 2025-2026, compared to the state average of 49.3%. This weakness is compounded by a high student-to-teacher ratio of 20.7:1, significantly higher than nearby schools like Montgomery Elementary (10.6:1) and Camelot Elementary (11.9:1). Additionally, the school spends less per student ($8,920) than many neighbors, such as Windcrest Elementary ($10,107), suggesting limited resources to address its challenges.
Despite this crisis, Idea Walzem has shown it can achieve high performance. In 2023-2024, 5th grade science proficiency soared to 45.3%, far exceeding the state average of 26.3%, and in 2022-2023, 5th grade math reached 62% proficiency. However, this success has not been sustained, and the school’s decline is universal across all student groups, with every subgroup ranking in the bottom 5-19% of the state. The most pressing question for the district is what changed in the last two years to cause this collapse and why the school cannot replicate its past achievements.
