The New York State Education Department prescribes the course of study at Holy Trinity Catholic Academy. Guided by the needs and abilities of the students, a local curriculum has been developed in each subject area. This is in accordance with the New York State Common Core Curriculum and by the Brooklyn Diocese. Students receive instruction based on these standards for learning in English Language Arts, (which includes reading), mathematics, science/health, social studies, physical education, technology, music, Italian, and art. The library is available to students; they may attend with their homeroom teachers.
