PMS –Scuti stars: theory versus observations

The importance of pre-Main Sequence (PMS) Scuti studies is discussed and recent developments from the observational point of view are reviewed. On the basis of the measured periodicities theoretical constraints on the position in the HR diagram and the evolutionary state are provided by computing suitable linear nonadiabtic models of PMS stars. Open problems concerning the possible occurrence of nonradial modes as well as the correct frequency evaluation are finally discussed.
