Perilaku agresif adalah perilaku yang secara sengaja diarahkan untuk menyakiti orang lain secara fisik, verbal maupun psikis. Menurut penelitian sebelumnya diketahui bahwa iklim sekolah dan keyakinan normatif mengenai agresi berperan dalam menyebabkan agresivitas. Tujuan penelitian ini adalah untuk mengetahui peran iklim sekolah dan keyakinan normatif mengenai agresi terhadap agresivitas siswa di sekolah. Survei melibatkan 471 orang siswa SMA sederajat kota Yogyakarta. Prosedur pengambilan sampel menggunakan multistage random sampling, yaitu teknik pengambilan sampel atas populasi yang mempunyai karakter berstrata dan berklaster. Data penelitian dikumpulkan dengan tiga jenis skala yaitu; skala agresivitas, skala iklim sekolah, dan skala keyakinan normatif mengenai agresi. Teknik analisis data menggunakan regresi linier berganda. Variabel iklim sekolah dan keyakinan normatif secara bersama-sama berperan terhadap agresivitas siswa dengan F hitung sebesar 84,933 (p < 0,01). Sumbangan bersama (R²) variabel iklim sekolah dan keyakinan normatif mengenai agresi terhadap agresivitas adalah 26,8%. Sumbangan efektif variabel iklim sekolah terhadap agresivitas siswa adalah 13,38%, sedangkan sumbangan efektif variabel keyakinan normatif mengenai agresi terhadap agresivitas adalah sebesar 13,42%.
