The data were from a national certification exam in medical technology. The responses of 178 repeat examinees were compared. The results indicate that the combined use of an adaptive algorithm to select items and latent trait theory to estimate person ability provides substantial protection from score contamination. The implications for constraints that prohibit examinees from seeing an item twice are discussed.
