Harvard-Westlake is 61st of 1,107 on UC admits and 2nd of 284 for Ivy-plus enrollment. Both numbers are right.
- Harvard-Westlake School is 61st of 1,107 California high schools on the UC Reach Score, and 2nd of 284 on our Ivy-plus board.
- Its own published list names New York University 26 times for the classes of 2021 through 2025, a destination a UC score cannot see.
- The gap runs both ways: Sage Hill School holds California's highest UC Reach Score, 151, and sits 56th of 284 on that same Ivy-plus board.
Two numbers, two questions
The UC Reach Score counts a school's admits to the six most selective University of California campuses. Admits are counted at each campus. So a senior admitted to Berkeley, UCLA and San Diego counts three times. That total is then set against the senior class, for every 100 seniors. For the class of 2025 we rank 1,107 California high schools this way.
Parents ask a second question too. Where do a school's graduates actually end up? Many schools answer it themselves. A matriculation list is where a school says its graduates enrolled. Harvard-Westlake prints one in the Harvard-Westlake School Profile 2025-2026. It covers the classes of 2021 through 2025 and names 192 colleges.
The two answers can look very different.
Harvard-Westlake, 61st and 2nd
Harvard-Westlake School had 283 seniors in the class we score. Its UC Reach Score is 62. That is 61st of 1,107 California schools.
Its own list reads another way. Those printed counts work out to 69.0 Ivy-plus enrollments per class year. That is 2nd of 284 schools on our Ivy-plus board.
The top of the printed list shows why. New York University, 26. University of Chicago, 14. University of Michigan, 13. Boston College, 11. Stanford University, 9. The same list puts the school 1st of 207 on our Michigan board and 2nd of 251 on our New York University board.
Both numbers are right. They measure different things. A score of 62 counts 62 top-six UC admits for every 100 seniors, counted at each campus. The printed list shows graduates heading to New York, Chicago and Ann Arbor. A UC measure was never built to see that.
The gap runs both ways
| School | Type | UC Reach Score | UC Reach rank | Ivy-plus per class year | Ivy-plus rank |
|---|---|---|---|---|---|
| Harvard-Westlake School | Private | 62 | 61st of 1,107 | 69.0 | 2nd of 284 |
| Sage Hill School | Private | 151 | 1st of 1,107 | 19.3 | 56th of 284 |
| The Harker School | Private | 126 | 5th of 1,107 | 42.0 | 10th of 284 |
| Henry M. Gunn High School | Public | 79 | 22nd of 1,107 | 36.0 | 21st of 284 |
Sage Hill School has the highest UC Reach Score in the state. Its own list, for the classes of 2023 to 2025, puts it 56th of 284 for Ivy-plus enrollment. Two schools in the table sit near the top of both measures. The Harker School is 5th and 10th. Henry M. Gunn High School is 22nd and 21st.
So read the UC Reach Score when the University of California is the plan. Read the school's own list when you want to know where the graduates went, and check the class years printed at the top of it. On a school page both sit together, with the document they come from.
What this data is
Every figure here comes from a school's own published list, copied as printed. The class years are the ones each school states, and they differ from school to school. Counts are as printed, and a names-only list carries no counts. Boards rank each school's printed counts for every graduating class.
