Founded in 1966 by the Diocese of Rockville Centre, St. John the Baptist is a coeducational, comprehensive college preparatory school which offers a variety of courses to maximize each student’s potential. Integrity, respect, responsibility, and service to others are representative of the qualities of character that we instill in each student at St. John’s.

Our mission is to develop each student intellectually, spiritually, and emotionally. They are challenged every day to discover more about God, themselves, and their responsibilities to the world. It is through rigorous academic work and a comprehensive Campus Ministry program that we prepare students to become dynamic leaders and responsible and caring adults who are active in school, church and community.

Academic excellence and personal development are highly valued at St. John’s. Students can choose from a variety of course offerings and each student can receive individualized guidance on course selections and collegiate applications. Fifteen College Credit Courses, fourteen Advanced Placement, as well as Honors and Regents level courses are offered, with a wide array of electives. We host over 50 moderated clubs. Our research programs, GENESIS & AP Capstone, enable selected students to create and execute their own original projects. For students with an Individual Educational Plan (IEP), we offer a fully staffed Resource Room, in conjunction with our local school district.

St. John’s boasts extensive state-of-the-art facilities for academics: a new collegiate Library/Tech Center, Science labs, Mac & PC Computer labs and a Performing Arts Center. In addition, SJB is a Google School with a closed-circuit TV studio, video production lab, a dance studio, music rooms, radio station, and fine arts classrooms, including a photo lab.

Beginning in the 2018-2019 school year, St. John the Baptist will be launching a one-to-one program! Each incoming student will be issued a Google Chromebook that will be used for instructional purposes both in and out of school. SJB is excited to take the next step in providing our students with the best possible resources for a 21st century education.

Our athletic facilities and programs have provided the foundation for our interscholastic teams and physical education classes. We offer over 80 interscholastic teams, a newly renovated turf field and gymnasium, a state-of-the-art track, a modern tennis complex, as well as an aerobic and strength training facility.
