Original Research by School Decision on Harlandale Isd Stem Echs-alamo Colleges at Pac
Harlandale ISD STEM ECHS-Alamo Colleges at PAC is a four-year public high school serving grades nine through twelve in San Antonio's south side. It is the district's dual-credit early college high school, housed on the grounds of San Antonio College's Palo Alto Campus.
The school's structure combines high school graduation pathways with college-level coursework. The "STEM ECHS" designation marks it as the district's science, technology, engineering, and mathematics-focused early college high school. Students earn college credits while completing high school requirements, and enrollment is open to district residents who apply; admission does not require prior high academic standing. The school has been open through the most recent reporting cycle.
On the state proficiency assessment, the school posted strong baseline results for overall grade-level proficiency across all tested subjects. In English language arts, proficiency tracking showed solid underlying skills; math proficiency was lower in reach but showed particular strength in foundational understanding. Science results were among the strongest shown. Social studies achieved full mastery of the foundational threshold. These results come from a single year of testing and represent the first full data set available for the school.
The student body is overwhelmingly Hispanic, reflecting the broader south-side demographics of San Antonio. A substantial majority of students qualify for free or reduced-price lunch, placing the school in a lower-income enrollment bracket. The grade distribution shows typical four-year high school distribution, with roughly similar cohorts moving through each year.
The school's location in a modest-housing-value zip code in south San Antonio places it in an area where home values are lower than state and national benchmarks. Median rent as a share of household income is moderate, and the housing market shows some pricing pressure but remains more affordable relative to other parts of the metro area. The south side neighborhood is part of San Antonio's broader affordable housing strategy and newer development corridor.
A parent weighing this option should understand that the school offers a clear credential pathway: dual enrollment that produces college credit alongside a high school diploma, housed on a college campus. This appeals to students who want to compress time and cost in pursuit of a degree and to families seeking structured post-secondary preparation. The STEM emphasis signals strength in math and science sequences. The relatively low math mastery-level performance, compared to approaches proficiency, may warrant a conversation with the school about support structures for students working at the meets rather than masters tier. The school's single-year test results and newer operational presence mean a parent may want to ask the school directly about trend data, graduation rates, and the college-credit completion rate and types of credentials students earn before finalizing enrollment.
