With a great emphasis on understanding teacher satisfaction in designing and improving professional development programs (PDPs), this study investigated the intrinsic and extrinsic aspects of satisfaction among Malaysian English as a Second Language (ESL) primary school teachers after finishing their first-degree program. A mixed-methods design was employed by using both quantitative methods (by administering survey research) and qualitative methods (through the use of items of the semi-structured questionnaire). The survey questionnaire was adapted from OECD Teaching and Learning International Survey (TALIS) questionnaire to measure the level of intrinsic and extrinsic teacher satisfaction among the samples. Descriptive analysis was used to analyse the survey research data collected from 30 secondary school English language teachers in Kuala Terengganu, east coast of Malaysia. The findings revealed that personal gains did not contribute much to PD activities in relation to the level of the teacher's extrinsic satisfaction after following their first-degree PD program. The study indicates that teachers differ from each other in terms of the source of their motivation for PD, whether intrinsic or extrinsic, and the type of development they aim for. This is hoped to show direction to the policymakers and organizers of PD programs in enhancing the program by taking into consideration of the teacher satisfaction, seniority, and professional background.
