The aim of this study is to determine the relationship between the time management skills and academic achievement of students who are potential teachers studying in faculties of education. The research was conducted in the 2007-08 academic term among 849 graduate students in the Faculty of Education at Gazi University. The "Time Management Questionnaire" was used in the research. The results of the research were analysed by using arithmetical mean, standard deviation, simple correlation, and regression analysis techniques. As a result of the research it was determined that student behaviour in the category of time planning was at the highest level and behaviour in the category of time consumers was at the lowest level. The success of the students was above average. There was a significant and positive relation between time planning and time consumers and the academic achievement of the students; there was a low and positive relation between time consumers and academic achievement; there was a meaningful and moderate relation between time management and academic achievement. The relative importance order of the predictor variables on academic achievement, according to the standardized regression coefficient, was time consumers, time planning, and time attitude; each of the three variables had an important predictor effect on the academic achievement of the students.
