Portland Private High School Elite College Placement Index
An objective, data-driven analysis of private high schools in the Portland Area. We use a proprietary Elite College Placement Index (ECPI) to evaluate schools based on graduate outcomes and college readiness.
The Portland Area's Private School Landscape
The Portland metropolitan area, known for its progressive culture and stunning natural beauty, also features a vibrant and highly competitive private school scene. The story of elite college placement is largely defined by a collection of academically rigorous, non-sectarian preparatory schools with national reputations, alongside a strong and influential network of Catholic schools that have educated generations of Portlanders. These institutions serve as the primary private pipelines to the University of Oregon, Oregon State University, and top-tier universities across the nation, creating a distinct and competitive educational pathway for families in the Willamette Valley.

Data Sources & References
This project synthesizes data from multiple sources to create a comprehensive, illustrative model of college matriculation patterns for private schools. Due to the varied reporting standards among private institutions, our model is based on a combination of the following:
Primary Data Sources
- Publicly Available School Profiles & Matriculation Lists: The most detailed data comes from high-achieving private schools that voluntarily compile and publish multi-year lists of their graduates' college destinations on their websites.
- School-Reported Data: Information gathered from school viewbooks, annual reports, and direct communication with admissions offices.
Secondary & Supporting Sources
- Third-Party Data Aggregators (e.g., Niche.com, Private School Review): These platforms compile data from various sources, including user surveys, self-reported school data, and public records. This data is used for cross-referencing and modeling, particularly for out-of-state and private university placements.
- National Center for Education Statistics (NCES): Provides foundational data on school demographics, enrollment, and accreditation for private schools through the Private School Universe Survey (PSS).
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 unless otherwise noted. Families should always consult a school's official profile and speak with school 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 University Matriculation (20%): Based on the percentage of graduates attending the University of Oregon or Oregon State University.
- 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 average SAT/ACT scores, AP/IB course offerings, and college counseling resources.
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. A school with the lowest raw score in a category receives a 0, the highest receives a 100, and all others are scaled proportionally.
- 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 Portland private school context.
