This study examines the Will, Skill, Tool model for predicting technology integration among prospective and practicing teachers in Ghana. Data was collected from 120 prospective mathematics teachers and 60 practicing mathematics teachers using validated instruments measuring attitudes, skills and competencies, access, and technology integration proficiency. Regression analysis found that teachers' lack of anxiety was the most important attitudinal dimension, and skill was the strongest predictor of technology integration. There were also significant differences between practicing and prospective teachers in computer competencies and access levels.
