Abstract: Based on the theory of planned behavior (TPB)， a sampling survey is administered to construct the behavioral intention model of registering for civil service examination. This model includes such variables as intention， attitude to examination taking， subjective norm， perceived behavior control， behavior belief， normative belief and behavior control. To test this models parameter estimation， the partial least square method is applied， whose results show that the precision of parameter estimation is not only high but also reasonable， with every fitting mode meeting the requirements and predicting the behavioral dispositions well. It is found that subjective norm， perceived behavior control and attitude to examination taking exert significant influences， among which the influence of subjective norm is the biggest， perceived behavior is intermediate， and attitude is the least. On this basis， the causes for civil service examination hit are analyzed and several corresponding suggestions are put forward.
