Objective To develop a formative evaluation program based on PBL teaching and to apply it initially. Methods A course team was established，and a formative evaluation program based on PBL teaching was developed through the evaluation of the current situation of PBL teaching，literature review and expert meetings. This evaluation program covered the main stages of PBL teaching（scenario creation，self-directed learning，group cooperation，and achievements exchange）. The program included 4 first-level indicators and 15 second-level indicators and the corresponding evaluation standards. The evaluation program was initially applied in the PBL teaching of Geriatric Nursing in 60 nursing undergraduates. After the course teaching，students’ formative evaluation scores were recorded and their satisfaction level was surveyed. Results The total score of the PBL teaching formative evaluation was（78.42±2.58），and the overall satisfaction with the course evaluation plan after the course was 83.33%. Conclusion The evaluation program is in line with the professional training objectives and PBL teaching objectives，and is operable. Students are satisfied with the program.
