Endorsements
Guidelines developed by other organizations where ASTRO is invited to participate may be considered for endorsement. ASTRO prefers to have one or more representatives on the task force, to peer review the draft guideline and then to receive a final version for endorsement consideration. All endorsed documents must be approved by ASTRO’s Board of Directors. See the collaborative guideline development page for more detail.
