Abstract :
The computerized self-adaptive test (CAT), a kind of education assessment method is discussed in this thesis. It relates the disadvantages of the conventional evaluation methods, which will be replaced by the CAT. The latter has many advantages. It analyses the mathematical model - thelogistic model, which is adapted to realize CAT. The three parameter logistic model is used to realize CAT through testing algorithms.
