Probably best to wait until Harvard releases data. The Crimson first year survey had a 78% response rate, which is high for any survey, yet potentially misleading when calculating average test scores and such. As a survey, all of this information is self-reported by the students as well, so not all of the answers may be accurate.
Further, I find it odd that The Crimson characterizes the average test scores as from admitted students. As these data are supposedly the results of their first year survey, it seems like the numbers must be for matriculants.
Perhaps they are mixing sources though (maybe received admitted data from the school?), and not divulging that. There is also no mention of cutting the data by those who applied TO, which obviously is a critical piece of information.
Admitted students from the Class of 2025 had an average SAT score of 1494 and an average ACT score of 34. These numbers varied significantly along athlete and income status. Recruited athletes had an average SAT score of 1397, whereas non-athletes averaged 1501. The average SAT score of students with family income under $40,000 was 1443, while those with a family income of more than $500,000 averaged 1520. Legacy students also had a higher average SAT score than non-legacy students, at 1523 for legacy students and 1491 for non-legacy students.
