Summary

Harlandale Independent School District (ISD) STEM ECHS-Alamo Colleges at PAC is a small, specialized early college high school in San Antonio, TX, serving 393 students in grades 9-12 and operating as a magnet program within the Harlandale Independent School District (Isd).

This school is a standout performer, consistently earning a 4-star rating and ranking in the top 15% of all Texas high schools, a remarkable achievement given that the district overall is ranked in the 16th percentile. While nearby comprehensive schools like McCollum High School and Harlandale High School struggle to reach the 20th percentile, this school operates at the 85th percentile or higher. It has achieved a 100% graduation rate in three of the last five years and a 0.0% dropout rate in four of the last five years, a stark contrast to the district average of 88.4% graduation and 1.5% dropout. The school also dramatically outperforms its district in core subjects like Biology (89.7% proficient vs. 57.8% district) and English II (86.2% proficient vs. 46.5% district). Notably, it is exceptionally effective at serving students from low-income backgrounds and those in special education, ranking in the 91st and 95th percentiles statewide for these groups, respectively.

Despite these strengths, the school has a notable weakness in Algebra I, with only 25% proficiency, well below the state average of 54%. It also shows a "Gifted and Talented" paradox, where its performance with high-achieving students is only average (57th percentile), suggesting its model excels at bringing struggling students up to proficiency but may not push top performers to the highest levels. The school is a model of efficiency, spending just $8,735 per student—roughly half of what other struggling schools in the area spend—while achieving top-quartile results. With a high student-teacher ratio of 24.6:1, the school's success underscores the effectiveness of its focused early college model and strong student culture.
