An evaluation was conducted of teachers' attitudinal perceptions of their confidence for implementation, stages of innovation adoption, and satisfaction, as a result of participating in the International Society for Technology in Education's National Educational Technology Standards-Teachers (ISTE NETS*T) Certificate of Proficiency Capstone Program. The Self-Efficacy and Stages of Concern instruments provide insight into the attitudinal progression of program participants. Data were collected at pre, mid, post, and follow-up points. Results showed that the capstone program is effective; participants were clearly more confident that they could implement the technology-based/enhanced teaching/learning strategies in their schools; had far fewer concerns about their level of preparedness; were anxious to work with others in their schools; and believed their school/classroom climate was conducive to and supportive of technology integration. Additionally, participants' principals and/or supervisors were asked to provide data on their perception of the influence the capstone courses had on their teachers.
