The content creation system comprises: an operation measurement device 1 that acquires, as measurement information, a three-dimensional work operation of a model worker R1 that performs the work of the work procedure; an evaluation criterion creation device 2 that creates evaluation criterion information on the work of the work procedure, based on the measurement information of the three-dimensional work operation; and a content creation device 3 that creates and updates the training content, based on the measurement information of the three-dimensional work operation, the evaluation criterion information and the three-dimensional shape information of the work target device. The work management server 2 creates the evaluation criterion information, based on distance information of the three-dimensional work operation with respect to the three-dimensional shape in specific stage of the work procedure, on the condition that a predetermined body motion of the model worker R1 is detected.
