Student and faculty member using a VERT classroom learning tool as part of the curriculum for the Radiation Therapy Program for training to become a radiation therapist.

Student experiences

The Radiation Therapy Program is designed to provide you with experience in all areas of radiation oncology. Courses take place in a specific sequence, progressively building on your expertise as you advance through the program. Academic coursework is coordinated with clinical rotations to optimize the learning experiences.

Classroom learning

This program is a full-time program. You will spend an average of 15-20 hours a week in classroom lecture (didactic) instruction, with the remaining time in clinical training and rotations. You are responsible for purchasing navy blue scrub uniforms to wear during all clinical rotations.

Clinical training

You’ll begin observing and working with patients as soon as the second week of the program. After morning didactic lectures, you’ll apply your knowledge immediately in clinical training. During your clinical education, you’ll observe and participate in special treatment techniques, including:

  • Deep inspiration breath hold
  • Stereotactic body radiation therapy
  • Total body irradiation
  • Proton beam therapy
  • Intraoperative radiotherapy (IORT)
  • Brachytherapy
  • Leksell Gamma Knife radiosurgery

On-site rotations

During monthly rotations, under the supervision of qualified radiation therapists and in collaboration with several members of the health care team, you have learning opportunities in all aspects of radiation oncology, simulation, treatment, and dosimetry.

Off-site rotations

All students participate in off-site rotations to Mayo Clinic Health System locations in Mankato, Minnesota; Northfield, Minnesota; and La Crosse, Wisconsin. Students may also elect to rotate to the radiation oncology facility in Albert Lea, Minnesota.

The purpose of the off-site rotations is to provide students with experience at smaller, non-academic cancer centers. Students will have the opportunity to see different treatment techniques, equipment, and enhance their ability to adapt to a new center’s routine in preparation for employment.

Students are responsible for driving to these sites for a two- or three-day rotation. While it is your responsibility to commute to these sites, Mayo Clinic provides assistance with housing and travel. During the rotation, you receive didactic course work via a videoconferencing system. It is recommended that each student have his or her own laptop computer to complete homework assignments while off-site.

Professional liability

Mayo Clinic provides professional liability insurance for learners in relation to their radiation therapy program educational activities.

Hands-on experience during Radiation Therapy Program at Mayo Clinic College of Medicine and Science

Ample hands-on patient experience

"This program prepared me for my career by providing me with ample time to learn and participate in CT simulation, dosimetric planning, and radiation treatment. This program gave me a great educational and clinical foundation in these modalities to feel confident in my role."

- Kristen Dezell, RTT, graduated in 2018 and is now a medical dosimetry student at Mayo Clinic's campus in Minnesota.


Mayo Clinic's campus in Rochester, Minnesota, includes an extensive outpatient complex, Mayo Clinic Hospital — Rochester, and substantial research and education facilities. This Mayo Clinic site is among the largest, most advanced medical centers in the world.

Mayo Clinic's Department of Radiation Oncology has exceptional patient care facilities with advanced therapy equipment, which includes:

  • Six Varian TrueBeam linear accelerators with View Station and ARIA treatment verification software
  • Two Siemens CT simulators
  • An Xstrahl orthovoltage unit
  • An integrated brachytherapy unit
  • A dedicated linear accelerator intraoperative therapy suite
  • A Leksell Gamma Knife
  • Proton Therapy

In addition, Mayo Clinic Radiation Oncology has a proton beam therapy treatment program that includes four treatment rooms equipped with intensity modulated pencil beam scanning, two CT simulators, and a MRI unit. Students have two rotations through the proton center, allowing them to gain experience with this newest treatment modality. Our students also participate in dosimetry planning utilizing Eclipse 3-D and IMRT-capable planning system.

Hours and schedule

For the majority of the program, your learning schedule includes eight-hour days, five days a week. Hours are 8 a.m. to 4:15 p.m., Monday through Friday. There are also two clinical QA labs conducted on a Saturday morning in February and March. Students will participate in morning quality assurance procedures one day per week from April through July. The hours for QA days will be 6:30 a.m. - 2:30 p.m.

Course sequence

The Radiation Therapy Program requires completion of three semesters of courses, which totals 45 upper division credits. All courses are taught in Rochester, Minnesota, using a combination of face-to-face and virtual delivery.

Grading and evaluation

All course work must be completed with a grade of a C or above. The grading scale is below. As you move through the Radiation Therapy Program's clinical rotations, you will be evaluated in each clinical area by the supervising therapists and the clinical supervisors. A competency-based evaluation system and performance appraisal forms are used to evaluate clinical performance.

Grading scale

Didactic and clinical course work is graded on an A to F scale. Grade points of A = 4.0, B = 3.0, C = 2.0, D = 1.0, and F = 0 for each credit hour earned will be assigned on the Mayo Clinic School of Health Sciences transcript.

Mayo Clinic School of Health Sciences uses evaluative tools that include: Written examination, oral presentation, demonstration of skills, and faculty reviews. Failure to meet or maintain the academic or clinical standards may necessitate remedial work of subject matter, as well as possible evaluation for probation or dismissal. 

Mayo Clinic's system of evaluation provides students and faculty with a comprehensive look at individual performance. This allows faculty and administrative staff to direct students who are experiencing academic difficulty to the appropriate support resources, including tutoring programs and counseling opportunities.

Meet the faculty

The Radiation Therapy Program is coordinated and taught by the clinical, scientific, and technical staff of Mayo Clinic. These include radiation therapists, dosimetrists, nurses, physicians, and physicists from the Department of Radiation Oncology.
