Subjects' selection for secondary school students is an important activity. This study investigated factors associated with subjects' selection of secondary level students. Objectives of the study were: finding out factors associated with subjects' selection of secondary school students and developing recommendations for appropriate subjects' selection. The design of the study was quantitative. The population was 30439 students. A sample of 380 was made through a simple random procedure.  A questionnaire was developed as a tool for collecting data. The tool was self-used for data collection, and the data were analyzed with mean scores and a test of chi-square. The factors associated with students' subject selection were found to be parents, guardians, teachers, and siblings. Students' personal characteristics and outcomes of careers were also associated with the selection of subjects. Career guidance facilities for subject selection were recommended. Further orientation seminars were needed at the beginning of new sessions to assist students in subject selection.
