| Research Abstract |
A computerized adaptive testing system which is based on testlet response model was developed.
The system was evaluated through two procedures : one using real examinee's response patterns, and the other using generated ability scores.
Very high correlations between the true abilities and the estimated abilities were found through the first evaluation, and, through the latter procedure, it was confirmed that the system works fairy well.
