A method comprises receiving one or more plan parameters of a first radiation treatment plan for a first patient and one or more passing rate data for the first treatment plan; generating a predictive model for passing rate data from the plan parameters of the first radiation treatment plan and the passing rate data for the first treatment plan; receiving one or more plan parameters of a second radiation treatment plan for a second patient; and applying the predictive model to the plan parameters of the second radiation treatment to generate one or more predicted passing rate data for the plan parameters for the second patient.
