The present study investigates the variables that are believed to influence learners’ in-class Willingness to Communicate (WTC). A total of 247 EFL undergraduate students participated in the study, who were studying in two colleges in Kuwait. The study was conducted with a quantitative research design by using a modified questionnaire to measure the Instructional Willingness to Communicate (IWTC). The adapted questionnaire, which was developed by Khatib & Nourzadah (2015), comprises six IWTC components containing 27 items. The data for each component was presented and followed by a detailed descriptive analysis. The findings revealed that learners’ willingness or unwillingness to communicate is made up of specific influencing variables in several situations within the classroom. The study sheds light on the role of the EFL classroom environment on learners’ communication behaviours. Discussing the results provided some pedagogical implications for language teachers and program designers. Suggestions for further research were provided.
