Bishop Ford Central Catholic High School will close its doors after this academic year, the school said in a letter to parents published on its website Monday.
The co-ed Catholic school, founded in Brooklyn in 1962, will shut on June 30 after final exams and Regents are completed.
"I know that this is very upsetting and sad news for you and for your children," wrote Principal Thomas P. Arria Jr. in a letter to parents. "It is no less sad for the faculty and scores of alumni who have remained loyal and dedicated to the mission of Bishop Ford."
School officials blamed declining enrollment for the decision.
"In 2006, Bishop Ford had 1,347 students," the school said in a press release. "Today, that number is 499, a loss of 75% of our student population since 2006. The projected enrollment for next year is 422, a further decrease."
School official said tuition alone was not enough to keep the school in operation.
