High Schools in Seguin Independent School District (Isd)


Summary:

The Seguin Independent School District (Isd) in Texas serves 2,121 high school students across three distinct campuses: one comprehensive public high school and two specialized facilities.

Seguin High School is the district's mainstay, enrolling 95% of all high school students (2,020 students). It is the only school in the district with a 1-star rating and shows a slight upward trend in its state ranking percentile over the last three years. Its graduation rate of 93.9% is the highest in the district, and it outperforms the other two schools across nearly all academic metrics. However, it still lags behind state averages, with Algebra I being a particular weakness (only 23.95% proficient). In contrast, Mercer & Blumberg Learning Center (73 students) and Juvenile Detention Center (28 students) both hold 0-star ratings and serve specialized populations. Mercer & Blumberg has the lowest dropout rate in the district (0.7%), suggesting its mission is student retention rather than academic excellence, while the Juvenile Detention Center has a 0% graduation rate and the highest per-student spending ($42,280).

The most striking finding is the cost disparity: the Juvenile Detention Center spends over four times more per student than Seguin High School ($9,932), yet achieves 0% proficiency in several core subjects. Algebra I is a district-wide struggle, with both alternative schools recording 0% proficiency in the subject. For parents, Seguin High School offers the strongest academic foundation and graduation prospects, while Mercer & Blumberg appears focused on keeping at-risk students enrolled. The Juvenile Detention Center serves a transient, incarcerated population with unique challenges that standard metrics do not fully capture.
