The school serves students in grades 9 through 12. Loughlin was founded in 1851 and was the first high school in the Diocese (1853), but today is run independently by the Christian Brothers in the Lasallian educational tradition, which holds central the appreciation of each student's uniqueness.

In 2019, Loughlin enrolls nearly 650 students, making it the fifth-largest Catholic high school in Brooklyn and Queens.
