How We Measure: The Data Behind the Ranking
Matriculation vs. Acceptance
In accordance with Chicardgo School's official methodology, we explicitly evaluate verified matriculation (where students actually enroll and attend) rather than mere collegiate acceptance rates. For our Houston-specific index, we apply a tailored weighting system to account for the significant gravitational pull of Texas's elite in-state institutions (UT Austin, Texas A&M, and Rice) alongside national Ivy/Elite placements.
| ECPI Component | Weight | Analytical Description |
|---|---|---|
| T25 National University Matriculation | 30% | Based on the percentage of graduates attending a Top 25 National University. |
| T15 Liberal Arts College Matriculation | 20% | Based on the percentage of graduates attending a Top 15 Liberal Arts College. |
| Top Texas Public University Matriculation | 20% | Based on the percentage of graduates attending The University of Texas at Austin or Texas A&M University. |
| Other Top Texas University Matriculation | 10% | Based on the percentage of graduates attending other Top Texas universities (e.g., Texas Tech, Baylor, SMU, TCU). |
| College Readiness Score | 20% | Based on an internal score reflecting AP/IB rates, average test scores, and National Merit Scholar counts. |
