The Team Sport Assesment Procedure (TSAP) (Gréhaigne, Godbout & Bouthier, 1997) was originally developed for use in physical education programs at the high school level. Richard, Godbout and Gréhaigne’s (1998 & 2000) studies have looked at the different facets of integrating this procedure in elementary and middle school physical education programs in New Brunswick (grades 5 to 8). The purpose of this study is to continue the validation process of the TSAP in relation to activities that are often exploited in physical education programs and to develop simplified versions in order to better integrate students in the assessment process (peer assessment). The results of this study show that the TSAP and it’s modified versions provide valid measures which permit to discriminate different levels of performance in both soccer and volley-ball game play activities.
