This study investigated inclusion of epistemic value into Richardson and Watt Factors Influencing Teaching Choice (FIT-Choice) framework to produce a more robust, useful teacher motivation model. We specifically examined pre-service teachers' social utility value (SUV), personal utility value (PUV) and epistemic value regarding pursuing future professional engagement and development. Using principal axis factoring, we found four main factors: PUV, SUV, epistemic value--future value of knowledge (EVF) and persistence/satisfaction. These factors were then used in a structural equation model (SEM) to predict pre-service teachers' intentions to pursue future professional engagement. Results provided the following three insights: (a) SUV was the most consistent, positive predictor of professional engagement and predicted all dependent variables; (b) EVF was a newly identified factor and a positive predictor of pre-service teachers' desire to pursue a leadership position and (c) PUV negatively predicted planned effort and a desire to pursue a leadership position.
