The systems and methods can be used to provide an evaluation sequence that can determine and evaluate the performance level of a person at one or more basketball skills. The evaluation sequence for the person can include a first sequence of actions that are the same each person being evaluated for a particular skill and a second sequence of actions that is based on the results of the first sequence and may be different for each person. Once the first and second sequences have been completed by the person, the system can determine a performance level for the person for the skills being evaluated. ## Claims ### Claim 1 A system for evaluating player performance, comprising: at least one sensor for capturing images of a player performing a basketball shot for which the player shoots a basketball toward a basketball goal;
