The purpose of this research is to determine the correlation between selfdiscipline
and English-speaking ability among second-semester students of the
English Education Department at IAIN Kerinci. A total of 34 students participated
in the study, selected through convenience sampling. The data were collected using
two instruments: a self-discipline questionnaire and a structured speaking
performance test. The self-discipline questionnaire measured indicators such as
punctuality, consistency, perseverance, orderliness, and integrity.
