Among "Schools with 200-400 Students", view the boarding schools with the highest average ACT scores (2025).
For several key reasons (listed below), these comparisons are intended only as informal reference points for evaluating the ACT taking ability of a school's student body.
A school's average ACT score is based on a relatively small sample of students from year to year (typically less than 100 students for a graduating class).
Average ACT scores, then, can naturally fluctuate year to year while the quality of the overall program and strength of the student body remains consistent.
Schools in the list below are often separated by small statistical differences, which for all intents and purposes, are not meaningful in determining the overall strength of the student body between two schools.
As a final note: average ACT scores should never be used by a family as an expectation of what score they can expect their child to receive if they go to a particular institution.
