The following notes are based on a conversation in May, 1985, with William Ambler, Haverford Director of Admissions at the time our data were collected.
High school rank is very important, but the top 2-5% are treated differently than the rest, since "grades predict grades."
The average math score is higher than the verbal, and this had been a steady trend at Haverford at the time, although both had dropped on average, due to national trends.
Interview Academic Rating
The interviewer is looking for seriousness as well as achievement, and is trying to predict the response to Haverford classes and teachers. Before expansion of the College (the Class of `61 was roughly 450 students, the Class of `75 roughly 750), there was an attempt to predict specific Haverford professors' responses to the student. The interview was more important when the pool was smaller. Generally, the interview is not a very good predictor. It's a first meeting, and the student is often very tense.
As an example of a "risky" applicant, Bill Ambler gave the case of someone with:
On the whole the process is "like a jigsaw puzzle," where the relation of the pieces to each other is especially important.
The variable is the sum of participations in "leadership" roles and as athlete, musician, or actor.
Size of Applicant Pool
It was about 1000 when the Class of `79 were admitted, had reached 1900 by 1985.
The Final Decision
Positive factors included distinctive achievement, rare geographic background. Negative factors included poor language skills, performance below apparent ability level, unrealistic aspirations (e.g., premed, see above).
Each dossier was read twice. The first reader rated it, then the second rated on the same dimensions and raised questions. The two readers were usually the admissions director and the person responsible for the geographical area from which the applicant came.
The Dependent Variable
"Success," Bill Ambler suggested, "should be measured by where the person is twenty-five years from now."
