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.

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:
