ABSTRACT The study sought to find out how teachers manage instructional time at Adventist Senior High School in Kumasi. The main objectives of the study were to find out the effectiveness of teachers instructional time management at Adventist Senior High School, assess the challenges teachers face in managing instructional hours at Adventist Senior High School, and suggest strategies that could be adopted by the teachers to improve the use of instructional hours at Adventist Senior High in the Kumasi. Three research questions were posed to serve as directive to the researcher. Descriptive survey design was employed for the study. The study involved the teaching staff of Adventist Senior High School in the Kumasi Metropolis. A sample size of 108 teachers was used. A simple random sampling technique was used to select the teachers. Questionnaire was the main instrument used to collect data. The instrument was pretested for reliability and validity. Data gathered were analysed and interpreted using SPSS version 20.0. The findings revealed that teachers regularly planned time ahead of instructional hours. It further revealed that obstruction during contact hours, not adhering to the time table strictly due to administrative factors, interruption through co-curricular activities are some challenges associated with managing instructional hours. It was therefore recommended that the head should make it a policy that all meetings should be done after instructional hours to prevent interruptions on instructional hours. Strict adherence to the time table should be insisted on by the head, more teachers should be employed to reduce the work load of existing teachers, and the school administrators should regularly monitor teachers in class during instructional hours.
