This paper describes the extent of anger and aggression in a sample of secondary school students in the southern Philippines. A total of 650 students in both public and private schools completed a self-report survey of levels of anger and aggression, and homeroom teachers rated them on aggression. Results indicated that their overall levels of aggression and anger were average. Students in private schools had higher overall aggression and anger compared to students in public schools. Teachers rated males as having a higher level of aggression compared to females. Self-reported anger and aggression were significantly higher among older students, but teachers rated them as being less aggressive. The implications of these findings for intervention and future research are discussed.
