In 2003, faced with increasing growth in technology-based and large-enrollment courses, the College of Business Administration at the University of Central Florida opened a computer-based testing lab to facilitate administration of course examinations. Patrick Moskal, Richard Caldwell, and Taylor Ellis describe the development and evolution of the lab, detail the lessons learned from their experiences in developing the lab and accommodating continued growth, and discuss plans for further development. The college's sound initial planning and continued responsiveness to faculty and student concerns may serve as an example for other institutions considering implementing computer-based assessment on a large scale.
