This study focused on investigating impact of psychosocial problems on academic achievement of students in Aba educational zones. The study posed 3 three research questions and three hypotheses to guide the study. The researchers used a sample of 300 students in public senior secondary schools in Aba educational zones. Three (3) instruments on psychosocial problems were used for data collection and they were: stress level rating scale, anxiety level inventory scale and peer relationship rating scale. The internal consistencies of the instruments were established through Cronbach alpha statistical tool estimated at 0.79, 0-81, and 0.86 respectively. Using the Person Product Moment Correlational Coefficient (PPMCC) to analyze the data collected from respondents, the finding from the study shows that: psychosocial problems such as stress, anxiety and peer relationship correlate with student’s academic achievement. This implies that psychosocial problems contribute to student’s poor performance in examinations. Based on the findings, the study recommended that teachers should first identify causes of student’s poor performance before providing intervention programmes to foster proper adjustment and enhance academic performance.
