This paper is designed to explain Willingness to Communicate (WTC) in English as a second language (L2). Identified predictor variables constitute familiarity, self-perceived communication competence (SPCC), and motivation that influence the variability of WTC as criterion variable.  What the modeling techniques signify are various scenarios where predictability of WTC as a criterion variable will be ascertained using pathway analysis in increasing levels – simple pathway analysis to determine prediction of WTC based on each predictor such as familiarity, SPCC and motivation and to a more structured relationship established among interaction of predictor variables in different arrow indications as they predict Willingness to Communicate (WTC), deemed important for the researcher. Likewise, simple linear regression to multiple linear regression analysis indicate how each predictor variable will predict variations on WTC.
