The Mayo Clinic has apologized after sending out letters of acceptance to hundreds of students hoping to enter its medical school.
The Rochester institution says the letters were sent out by mistake to 364 "talented, engaging individuals seeking an appointment at the medical school."
After the "technical error" was realized, the clinic sent out emails withdrawing the offers, with each student who received a letter then contacted by phone.
"We deeply regret having caused disappointment and stress to these applicants, and we are continuing to investigate the issue," the Mayo said in a statement on Saturday.
The Mayo Clinic Alix School of Medicine only accepts around 50 candidates every year, with classes this year starting in July.
Those who have been accepted into the school will be informed of it via phone.
The Mayo is still investigating how the offers came to be erroneously issued, adding: "We are truly sorry to each of the students who were affected and are looking into the cause."
