Abstract: Systems and methods for radiation treatment planner training based on knowledge data and trainee input of planning actions are disclosed. According to an aspect, a method includes receiving case data including anatomical and/or geometric characterization data of a target volume and one or more organs at risk. Further, the method includes presenting, via a user interface, the case data to a trainee. The method also includes receiving input indicating an action to apply to the case. The input indicating parameters for generating a treatment plan that applies radiation dose to the target volume and one or more parameters for constraining radiation to the one or more organs at risk. The method includes applying training models to the action and the case data to generate analysis data of at least one parameter of the action. The method includes presenting the analysis data of the at least one parameter of the action.
