An evaluation method for a computer to execute a process includes, acquiring a plurality of pieces of skeleton information in time series based on position information of joints of an object that executes a plurality of motions; specifying a transition period between a first motion and a second motion that follows the first motion, which are included in the plurality of motions based on the plurality of pieces of skeleton information; determining whether the transition period is related to a certain combination of motions by inputting skeleton information among the plurality of pieces of skeleton information that corresponds to the transition period into an evaluation model trained to evaluate a transition period between motions based on a plurality of pieces of skeleton information in time series; and outputting an evaluation result of the transition period by the evaluation model.
