There is a lack of research in the area of the influence that task autonomy (TA), organizational learning (OL), and group cohesiveness (GC) can have on technical education teachers' innovation of professional development (IOPD). Therefore, this study aimed to probe into the influences of TA, OL, and GC on IOPD by technical education teachers, and their relationships. We conducted a questionnaire survey on 265 full-time teachers. The results showed that TA, GC, and OL of technical education teachers revealed significant positive relationships with the degree of IOPD. The teachers' TA and OL are critical factors to their IOPD, as they are positive predictors. (Contains 2 tables and 1 figure.)
