The purpose of this research is to automatically construct multiple equivalent test forms that have equivalent qualities indicated by test information functions based on item response theory. There has been a trade-off in previous studies between the computational costs and the equivalent qualities of test forms. To alleviate this problem, we propose an automated system of test construction based on the Bees Algorithm in parallel computing. We demonstrate the effectiveness of the proposed system through various experiments. (Contains 6 tables and 6 figures.)
