Summary

Southwest Preparatory School-Northwest in San Antonio, TX, is a small charter school serving 141 students in grades 6-12, located in a predominantly low-income area where nearly 70% of students qualify for free or reduced lunch.

The school stands out for its remarkable graduation rate of 94.7% for the 2023-2024 school year, which surpasses nearby larger schools like Jay High School (87.1%) and Memorial High School (80.5%), and rivals Warren High School (94.5%). This is a dramatic improvement from just two years prior when the rate was 67.6%. The school also offers an extremely low student-teacher ratio of 10.2:1, much smaller than nearby comprehensive high schools like Holmes High School (14.4:1) and Warren High School (16.3:1). However, academic proficiency remains a challenge, with only 21.43% of students proficient in Algebra I compared to 54.03% statewide, and math scores lag behind similar charter schools like Idea Monterrey Park College Preparatory (64% proficient in Algebra I).

Despite these academic struggles, the school shows strengths in U.S. History, where 64.29% of students were proficient, outperforming its Southwest Preparatory School district average of 50%. The school also demonstrates efficiency compared to the Alternative High School, which spends $134,204 per student but has no reported graduation rate, while Southwest Prep achieves its high rate with about $11,478 per student. For parents, this school offers a supportive, small environment that excels at getting students to graduate, but families focused on rigorous academic preparation may find stronger options at nearby Idea Public Schools like Idea Ingram Hills College Preparatory.
