This paper examines the student, program delivery and school factors that influenced student achievement in the Cisco Networking Academy. The Academy uses the Internet to distribute a centrally developed curriculum and standards-based online testing, and combines that with local instructors who teach classes to students. This study, conducted with 10,371 students at 1,651 schools, found that individual student ability, gender, age, and motivation were the most important influences on student achievement. Instruction quality was also important, but unlike prior studies, the impact of school level factors was small. We conclude that this combination of centralized curriculum, standards-based testing, and local instruction worked equally well in a variety of environments and enabled students to reach their own potential.
