May 1, 2021.  Update!  The Manual for the Special Distinction in Stereotactic Radiotherapy is now available to read and download:

February 25, 2021.  ACRO and the Radiosurgery Society® (RSS) are pleased to offer a new Distinction in Stereotactic Radiotherapy. The Distinction in Stereotactic Radiotherapy program is the only SRS/SBRT-dedicated accreditation review by a professional medical society that focuses on practice standards, patient management and medical physics aspects unique to SRS/SBRT treatment. The program was designed by professional peers with extensive experience treating patients with SRS/SBRT, with the aim to identify standards indicative of a quality practice in the field of SRS/SBRT. The Distinction in Stereotactic Radiotherapy program currently focuses on SRS/SBRT treatments within six (6) disease sites: central nervous system (CNS), spine, liver, lung, pancreas and prostate. Centers who wish to apply for Distinction in Stereotactic Radiotherapy need to apply and complete the ACRO Accreditation Program for radiation oncology.  Read the full press release or learn more about the partnership.

Please do not hesitate the contact the ACRO Accreditation office by email at, or by phone at 206-956-3642 with any questions or comments.

Thank you for your interest in the accreditation program of the American College of Radiation Oncology (ACRO).

As part of its mission, ACRO developed a practice accreditation program in 1995, consisting of practice standards for radiation oncology. Accreditation is a voluntary process in which professional peers identify standards indicative of a quality practice, and an audit is conducted to assure that these standards are followed.

Since its establishment, the accreditation program has undergone periodic revisions to reflect clinical and scientific advances within the field, providing for the safe and effective practice of radiation therapy. The most recent in-depth review carried out in 2010 resulted in major changes to the process by introducing online case submissions by each practice with online review by disease site specific team members, and a quicker turnaround time for the full accreditation process, including onsite visits by physics and administrative surveyors.

If you are interested in applying for ACRO Accreditation (or re-accreditation) please apply below. If an application is cancelled by the practice after payment, a refund of up to 25% of the fee will be considered based on the reason(s) for cancellation and the work already completed by ACRO Accreditation. Refunds are not guaranteed.

ACRO Accreditation recently conducted a study comparing onsite chart reviews to online chart reviews by a radiation oncologist. Read the full article here.
