Objective Functions for Item Exposure Control in Computerized Adaptive Testing
Item exposure control in computerized adaptive testing (CAT) is often achieved through procedures which do not take latent trait estimation precision directly into account. This results in good item exposure control, but at the cost of estimation precision. This study investigates a new approach which directly addresses both of these goals and compares its performance to other procedures. Results suggest that this new approach is effective, but the effect is quite small. Nevertheless, these findings indicate that a balance between these goals is achievable and that further research may be able to find a way to increase the size of the effect of pitting these goals against each other.
