How does St. Andrew's School (Delaware) Compare to D.C.-Area Private Schools
By Data Team | Published September 1, 2026
Our analysis of St. Andrew’s School Delaware’s matriculation data for the Classes of 2022-2025 indicates a strong Top 25 National University and Top 15 Liberal Arts placement pipeline. Operating in Middletown, Delaware, this 318-student, 100% boarding institution utilizes a proprietary advanced curriculum to generate an Ivy+ yield comparable to the leading prep schools in the Washington, D.C. corridor.
Because Delaware currently lacks a dedicated metropolitan Elite College Placement Index (ECPI), our data models evaluate St. Andrew's against the Washington, D.C. market. For Mid-Atlantic families evaluating boarding models, this data signifies that St. Andrew's provides highly competitive access to Ivy+ and Top 15 Liberal Arts institutions. This placement pipeline is supported by a significant financial mandate: offering free tuition to admitted students from families with a household income under $150,000.
Summary of Key Findings
-
•
Top 25 National Concentration (36%): Based on the 2022-2025 graduating cohorts (~300 estimated students), St. Andrew's achieves an estimated 36% placement rate into Top 25 National Universities. This includes notable Ivy League cohorts at UPenn (15), Brown (14), Princeton (13), and Duke (10).
-
•
Top 15 Liberal Arts Footprint (18%): The school functions as a primary pipeline to Top 15 Liberal Arts Colleges, yielding consistent enrollments at Davidson (16), Hamilton (6), Wesleyan (6), Williams (5), and Amherst (4).

D.C. Regional ECPI Benchmarking: When evaluated against the Washington D.C. market methodology, our data models project St. Andrew's Delaware secures an Elite College Placement Index (ECPI) score of 88.45. This places it solidly in the #5 position among the Capital Region's strongest institutions, trailing Sidwell Friends, Potomac, BASIS McLean, and St. Albans.
Regional Context: The Elite Boarding Ecosystem
The Mid-Atlantic secondary education environment remains geographically fragmented, yet it is characterized by intense collegiate admissions competition. While St. Andrew's School is physically located in Middletown, Delaware, it draws a highly competitive applicant pool from 24 states and 11 foreign countries.
Unlike day schools in urban centers, St. Andrew's operates with a 100% boarding model. With a total enrollment of just 318 students and a graduating class averaging 75 seniors, the institution uses its endowment to maintain an intimate academic cohort. Because Delaware lacks the density of independent schools required to form a dedicated Chicardgo ranking index, assessing St. Andrew's necessitates benchmarking its placement data against the closest major competitive market: Washington, D.C.
- Global Geographic Diversity: The student body represents distinct geographic variety, allowing university admissions offices to recruit prepared students from multiple demographics while visiting a single Delaware campus. 13% of the student body are international students.
- The 100% Boarding Advantage: The absence of day students supports a collegiate-style residential experience. Faculty (65 total) live on campus, and seniors manage dorm life, fostering the independence prioritized by Top 25 admissions readers.
How We Measure: The D.C. Area ECPI Methodology
Applying the D.C. Standard
Because St. Andrew's School frequently competes for the same boarding-inclined applicant pool as Washington D.C., Maryland, and Virginia independent schools, our data models evaluate its placement data using the Washington D.C. ECPI Methodology. This index accounts for strong HBCU placements and localized flagship university retention unique to the Mid-Atlantic region.
| ECPI Component | Weight | Metric Description |
|---|---|---|
| T25 National University Matriculation | 35% | Modeled percentage of graduates attending a Top 25 National University (inclusive of Ivy+). |
| T15 Liberal Arts College Matriculation | 15% | Modeled percentage of graduates attending a Top 15 Liberal Arts College. |
| In-State/Regional Flagship Pipeline | 20% | Measures the strength of a school's pipeline to primary public universities (e.g., UVA, UMD, UDelaware). |
| HBCU Matriculation Strength | 10% | Measures matriculation to leading Historically Black Colleges and Universities. |
| College Readiness Score | 20% | An internal score reflecting curriculum rigor (Advanced Study), resources, and overall national reputation. |

Academic Rigor: Beyond the AP

- Advanced Study (AS): The primary collegiate-level designation. High-achieving students take four or five AS classes in their senior year.
- Advanced Topics Tutorial (ATT): A specialized track representing coursework pushing beyond the AS level, structured strongly around the STEM fields.
- The Exhibition Process: Across all four years, students orally defend analytical papers before student and faculty readers, culminating in a senior exhibition project followed by an intensive Oxford-style spring tutorial.
The Grading & Testing Structure
By omitting standard numerical class rankings, St. Andrew's requires university admissions offices to evaluate applicants based on individual academic portfolios and rigorous coursework.
- Class Rank & GPA: The school operates on a 0-100 scale but strictly does not rank students or mathematically weight honors/AS courses. The Class of 2026 holds a Mean GPA of 91.3.
- Freshman Transition: All fall semester courses for incoming 9th graders are strictly pass/fail to encourage intellectual risk-taking.
- Standardized Excellence: For the Class of 2026, the middle 50% SAT scores rest at 620-740 (Reading) and 600-720 (Math), alongside a 31 composite ACT average.
The Top 25 Pipeline
Our data models evaluate the aggregated 2022-2025 matriculation cohorts, comprising approximately 300 total graduates. St. Andrew's officially reports matriculations only where "two or more" students have enrolled. Therefore, our model adjusts for an estimated 7 to 10 single-student matriculations at highly selective universities omitted from the public list. Following this calculation, our analysis reveals an estimated 36% yield into Top 25 National Universities, headlined by sustained pipelines into the Ivy League.
