This dissertation examines the professional development needs of school leaders in preparation for a district-wide one-to-one computing initiative. The study found that school leaders need the most training in managing public-private partnerships, leading online meetings, and establishing long-term technology plans. Differences in needs existed based on leadership role, school level, and computer skill level. Recommendations include providing an instructional technology facilitator for each school, blended professional development models, and professional learning teams to ensure school leaders are fully prepared to lead one-to-one initiatives.
