The aim of this study was to develop an instrument to evaluate the educational program's training. The program used for this purpose was the Olympic Education Program, which has been implemented in Greek primary and secondary schools since 2000. First, the face validity of items was evaluated, second, the pool of the items selected was factor analyzed. Exploratory factor analysis indicated a three-factor solution with high internal consistency. The instrument, Professional Development Evaluation Form of the Olympic Education Program, consisted of three factors containing 21 items. The three factors obtained were "training", "study groups", and "total impression". The results provide adequate psychometric support for the instrument. The questionnaire seems a promising tool for the evaluation of professional development procedures. Although the results were encouraging, further research would be very helpful in order to improve the instrument. (Contains 3 tables and 1 figure.)
