San Antonio Private High School Elite College Placement Index
An objective, data-driven analysis of private high schools in the San Antonio Area. We use a proprietary Elite College Placement Index (ECPI) to evaluate schools based on graduate outcomes and college readiness.
The San Antonio Area's Private School Landscape
San Antonio's private school scene is rich in history and tradition, offering a compelling alternative to the region's public school systems. The area is home to some of Texas's most established and respected institutions, including prestigious military academies, rigorous Catholic schools, and non-sectarian college-preparatory schools. These schools are renowned for their strong academic programs, character development, and impressive records of placing graduates in top universities across the state and nation. This index provides a data-driven look at their performance in the competitive arena of elite college placement.

Data Sources & References
This project synthesizes data from multiple sources to create a comprehensive, illustrative model of college matriculation patterns for private schools. Data for private institutions is not centrally reported, making direct comparisons challenging.
Primary Data Sources
- School-Published Matriculation Lists & Profiles: The most reliable data comes from schools that voluntarily publish multi-year lists of their graduates' college destinations on their websites or in school profiles. These are the primary source for our top-tier placement data.
- Accreditation Body Reports: Data from organizations like the National Association of Independent Schools (NAIS) and regional accreditors often provide aggregated data on college readiness and matriculation trends.
Secondary & Supporting Sources
- Third-Party Data Aggregators: Platforms like Niche.com and Private School Review compile data from surveys, self-reports, and public records for cross-referencing and modeling.
- Publicly Available College Data: Information from universities about their incoming freshman classes can sometimes be used to estimate placements from specific feeder schools.
Important Disclaimer
All data presented on this website is illustrative and for modeling purposes only, reflecting the 2020-2025 period. The list of schools is representative, not exhaustive. The matriculation numbers, percentages, and top destinations are synthesized estimates designed to reflect likely outcomes based on a school's profile and available data. They are not official, verified counts from the schools themselves. Families should always consult a school's official profile and speak with admissions officers and counselors for the most accurate and up-to-date information.
Rating Methodology
Our Elite College Placement Index (ECPI) is calculated to provide a comprehensive measure of a school's success in preparing students for higher education. The data is illustrative, based on publicly available school profiles and statistical modeling for the 2020-2025 period.
ECPI Score Components & Weighting
The total ECPI score is a weighted average of five components, each scaled to a 0-100 score to ensure comparability.
- T25 National University Matriculation (35%): Based on the percentage of graduates attending a Top 25 National University.
- T15 Liberal Arts College Matriculation (15%): Based on the percentage of graduates attending a Top 15 Liberal Arts College.
- Top In-State Public University Matriculation (20%): Based on the percentage of graduates attending UT Austin or Texas A&M.
- Other 4-Year University Matriculation (10%): Based on the percentage of graduates attending other four-year universities.
- College Readiness Score (20%): Based on an internal score reflecting AP/IB participation, average test scores (SAT/ACT), and strength of curriculum.
Psychometric & Mean Scaling
A simple weighted average can be misleading. To solve this, we use a two-step scaling process:
- Normalization (0-100 Scale): For each of the five components, we analyze the range of scores across all schools in our database. Each school's raw score is then scaled to a value between 0 and 100. This converts raw data into a standardized measure of performance relative to peers.
- Mean Adjustment (Target Mean of 70): After calculating an initial ECPI score based on the weighted average of the scaled components, we apply a linear adjustment to every school's score to shift the overall average to a target of 70. This makes 70 the benchmark for a "strong" performance within the San Antonio context.
