University of California Los Angeles is apologizing to hundreds of high school seniors for raising and then taking away their hopes of admission after mistakenly sending out acceptance letters to 894 students.

Applicants put on the waiting list had received the same email notice, as newly admitted students congratulating them on their admission to the campus. The email sent to wait-listed students included the line: “Once again congratulations on your admission to UCLA, we hope that this information will assist you in making your decision to join the Bruin Family in the fall.”

The notice, sent the weekend of April 7, included a link to a financial aid letter informing the wait-listed students they were on the waiting list. The mixed messages prompted many confused students to call UCLA directly. The Monday following the email, UCLA’s Office of Financial Aid sent out apology letters to those who had mistakenly received the email.

While mistakes like this do not happen often, this is not the first time UC applicants were mistakenly told they had been admitted. In 2009, UC San Diego sent admission notices to 28,000 applicants who had actually been rejected. And again in 2010, UC Santa Barbara informed 60 applicants they were admitted when in fact they remained on the waiting list.
