Summary

Harmony Science Academy (San Antonio) is a K-12 charter school in San Antonio, TX, serving 718 students in the Harmony Public Schools - South Texas district, where a majority of students (73.4%) come from low-income households.

This school stands out for its exceptional high school outcomes, despite a challenging start in the early grades. While only 5.4% of 3rd graders were proficient in math in a recent year, by high school, students consistently outperform state averages on end-of-course exams. For example, in Algebra I, 67.9% of students were proficient, compared to 54% statewide, and in U.S. History, 80.7% were proficient versus 70.2% statewide. This upward trajectory suggests the school adds significant academic value over time. The school also boasts a remarkable 95.9% graduation rate and a 0.0% dropout rate, far surpassing nearby alternative schools like Reddix Center (0% graduation rate) and Holmgreen Center (4.9% dropout rate). Even compared to a highly-rated nearby charter, Great Hearts Western Hills, Harmony Science Academy outperformed it in Algebra I (67.9% vs. 22.8%) and U.S. History (80.7% vs. 72.9%), despite serving a more economically disadvantaged student body.

One area of concern is the volatility in math scores, particularly in middle school, where proficiency rates can swing dramatically from year to year. However, the school's overall efficiency is notable, spending just $10,823 per student—far less than nearby alternative centers like Reddix ($41,445) and Holmgreen ($85,836)—while still achieving strong high school results. For parents seeking a school that helps students grow academically from elementary through high school, Harmony Science Academy offers a compelling option, especially for those focused on college preparation and high school completion.

Open Quote This school needs to be audited by the state. I was not pleased to find out that they hire teachers who are not certified. These are the teacher whom I had issues with. They shouldn't be teaching. They don't have the skills to deal with students. They pick on students. One teacher even went as far as stepping on a students foot for a dress code violation. I had reported it to the school. Now that teacher is bully my son. The principal is never available to speak with the parents. I would advise everyone to avoid this school. Close Quote
