Summary:

The Southside Independent School District (Isd) serves the San Antonio area with nine schools, including five elementary schools, two middle schools, and two high schools, and is characterized by a high level of economic need, with most schools reporting free/reduced lunch rates above 84%.

Within the district, Heritage Elementary stands out as the top performer, consistently earning a 4-star rating and ranking in the 74th percentile statewide, significantly outperforming district and state averages in 4th and 5th-grade math and reading. In contrast, Southside High School is the most challenged, holding a 1-star rating with test scores below district and state averages and a higher dropout rate. A notable improver is Julian C Gallardo Elementary, which jumped from a 1-star to a 3-star rating, now exceeding district averages in 3rd-grade reading and math. The Southside Alter Center is an outlier with only 22 students and a 0.0% dropout rate, though its small size makes direct comparisons difficult.

Key metrics reveal a district with strengths in early education and specific subjects but challenges in high school performance. Elementary schools like Freedom Elementary and W M Pearce Pri show strong bilingual program results, with Spanish STAAR test-takers often outperforming English-language peers. Middle schools, including Losoya Middle and Julius L Matthey Middle, excel in 7th-grade math, beating the state average, yet this success does not carry over to high school Algebra I. Social Studies is a district-wide weakness from 8th grade through high school. The district's per-student spending is consistent across main campuses, ranging from $11,147 to $12,559, with an average student-teacher ratio of 16.0:1.
