An acceptance rate is the percentage of applicants who are accepted into a university/degree. It gives an indication of how competitive a course or university is and helps applicants assess their chances of receiving an getting in.
Offer rates can also be calculated in a similar way, looking at the percentage of applicants who received an offer to study at the university. These two rates will almost always be different, as not every applicant who gets an offer will ultimately be accepted, either due to not getting the right grades or choosing a different university.Â
This is especially useful when comparing selective institutions like Oxford or Imperial College London.
