The academic year is divided into fall, spring, and summer semesters. During the fall and spring semesters, students attend two days of classroom instruction and three days of clinical instruction. From the very beginning, students are assigned to various treatment units under the direct supervision of a licensed radiation therapist for their clinical instruction. Students have the opportunity to apply the techniques and principles covered in the classroom and learn to operate the equipment used in planning and administering radiation treatments.

During the summer semester, students attend five days of clinical instruction and other required clinical rotations. Students are also required to attend periodic Saturday clinical workshops where they get to put theory into practice. Students also have the option to rotate through our regional clinical sites for periodic month-long clinical rotations. The regional sites are:

Memorial Sloan Kettering Cancer Center Commack

Hours are to or to , Monday through Friday. Students are given 15 days-off per year, in addition to six observed holidays and a 5-day winter break and a 5 day Spring break. During the senior year, students get two professional days to be used for job-seeking activities and/or interviews. All instruction, clinical and didactic, takes place a tour main campus, with the option to rotate through our regional sites listed above.


Each didactic course is graded on a numerical scale from zero to 100%. 75% is passing in each course. Every course must be taken in sequence such that any student receiving below 75% will be dismissed from the program. Clinical performance is also graded in the fall and spring semesters as well as the summer semester and also must be passed with a 75%.

Our numerical grades can be converted to a letter grade based on the following scale:

Grade Letter Score
Below 75 F
75-76 C
77-79 C+
80-83 B-
84-86 B
87-89 B+
