This study use simulation testing method on the basis of item numbers and sample sizes. According to results, some conclusions are listed below: 1. Under the same item numbers, the more examinees make discrimination parameter and parameter of guessing determination power more accurate. 2. Under the same sample size, the more item numbers make parameter of guessing determination power the more accurate. And discrimination parameter, guessing parameter, correct power parameter, and distractibility parameter are no discrimination between good and bad. 3. Parameters used in this study are more than general parameter model. There has covariance between parameter estimation. The results reveal the large MSD of all parameter estimation. So it’s hard to find out the general estimation under the more item numbers and examinees. Keywords: non-parameter estimation for ability, parameter model, item parameters, number of examines
