This study adopted an ex-post-facto research design with which a saturation sampling technique was employed. The study population constituted 300 secondary school going orphans and 23 principals. The sample of the study comprised 300 secondary school going orphans and 7 principals picked out through saturated and simple random sampling respectively. The research instruments that were used were students’ questionnaires, document analysis and interview guide for the head teachers. The validity of the research instrument was ensured through expert judgments by University lecturers in the department of psychology. To test the reliability of the instruments, the researcher employed the test-retest and correlation coefficient of 0.891 was reported. The Pearson Product-Moment correlation coefficient (r = .906) computed indicated that there was high positive correlation between time management and academic achievement among orphaned secondary school students. Ministry of Education in general should understand the plight of orphans and provide them with improved services like trained counselors who would be able to provide orphaned children with appropriate counseling services.
