This study aimed to validate a questionnaire on Exploring Teacher’s Roles and Attitude in ESP Classes - a Case Study in Higher Education in Kosovo. Participants (n=215) were undergraduate students who have taken a Legal English course at the University of Prishtina for two semesters. Test reliability, internal reliability, and construct validity of the questionnaire were determined. Overall internal reliability (Cronbach's alpha= Cronbach’s alpha = 0.8377) indicated a high level of internal consistency. Construct validity for the questionnaire was satisfactory as the analysis proved p-value of 0.08, indicating correlation at 90% level of confidence.
