Abstract

 This research aimed to analyze the item quality of Pre O-NET examination,construct the Pre O-NET Item bank, and develop a computerized adaptive testing program for Pre O-NET at the grade six level, covering 4 learning areas. The computerized adaptive testing program was developed as a web application. Item quality of Pre O-NET examination was assessed using 3-parameter logistic Item Response Theory. The research methods of this study were divided into 4 steps: 1) Analyze the item quality of Pre O-NET examination for 4 learning areas, 2) Construct the Pre O-NET Item bank for 4 learning areas, 3) Develop the computerized adaptive testing program and 4) Evaluate the satisfaction of computerized adaptive testing program by assessingusers’ satisfaction.
