Four important conclusions were drawn. First, the CMLE method is the most suitable pro-cedure for parameter estimation in 1-parameter model. Second, the test construction of TIPS guided by classical test theory will not be valid for obtaining reliable measures. Third, the systemmatic ICC presenting method presented the perfect item and ability latent traits for the results in CMLE findings. Fourth, the complicated analysis of reliability coefficient and likeli-hood parameters met the precise and accurate measures of latent traits in either integrated process skills or hypothesizing skills.
