Information About Brad Hanson

Bradley Alvin Hanson was an extraordinary person who greatly enriched the lives of his personal friends and family, as well as his many professional colleagues. Brad died tragically in October 2002, the victim of a drunk driver.

This web site is dedicated to preserving Brad's professional contributions as he had organized and shared them before his death.

Brad's stellar career included many significant contributions to educational measurement. He conducted and published a body of research on methodology in test analysis, scaling, equating, reliability, and security. He authored numerous software programs, many of which he freely provided on this website. He was instrumental in incorporating his developments into systems used in a number of educational testing programs.

Brad earned his doctorate at Stanford University, and he worked for 16 years at ACT in Iowa City, Iowa, before joining CTB as Chief Research Scientist in 2001. Brad was a tremendously active and generous research collaborator with more than 50 publications and conference presentations. He was an active member of the American Educational Research Association, the National Council on Measurement in Education (NCME), the Psychometric Society, and the American Statistical Association; he was serving as the Web Site Editor for NCME.

Brad's service to the professional community was extensive and reflected his dedication to improving the quality of practice, research, and scholarship in educational measurement. Brad was a gifted mentor, serving on dissertation committees, working with graduate summer intern programs at both CTB and ACT, and providing guidance to entering professionals. His office door was always open to colleagues who wished to discuss an idea or ask for assistance. His professionalism, keen insights into psychometrics, formidable technical skills, and keen sense of humor are greatly missed by his colleagues. Brad's volunteer service continued outside the profession, where he served as treasurer of his Iowa City condo association, participated in blood drives, and led bike trips for a local bike group. Brad was an avid bicyclist, read science fiction, and played classical guitar. Brad is survived by his father, Bruce, and his brothers, Scott and Todd.

The Bradley Hanson Award is presented annually by the National Council on Measurement in Education. It honors Brad's contributions to the field of educational measurement and to further advance the goals embodied in his work.
