In designing and implementing the pilot program of serving principal training, the author of this paper learned the experience from what E. Bridges and P. Hallinger did but didn't imitate fully, rather, created several new strategies because Chinese principals faced different situation from their American counterparts. The pilot program introduced and implemented the Problem-Based Learning (PBL) approach. The outcome of this pilot program shows: (1) PBL is a promising approach to serving principal training in China in casting off the traditional "chalk and talk" lecture approach; (2) The actual learning of trainees will happen prior to the classroom sessions if a trainer lets trainees participate the process of problem identification in pre-training stage; and (3) PBL approach is much welcome and strong supported by local government and policymakers when the focal problem is related to implementation of current local policy.
