The Letters of Recommendation required on the Common App depend entirely on the individual university’s application requirements. Different colleges may ask for different combinations of counselor recommendations, teacher evaluations, or optional recommendations. Students should therefore carefully check each university’s “Recommenders and FERPA” section on the Common App as well as the university’s official admissions website.
In most cases, universities require: A school counselor recommendation and school report & One or two teacher recommendations from core academic subjects
Some universities may also allow or encourage an additional recommendation from a mentor, peer, or employer, if that person can provide meaningful insight into the student’s abilities and character.
