The aptitude and career interest were considered as the two dimension of the entrance guide system, and was proof-tested by the structural equation model, which results supported this two-dimension hypothesis. Accordingly, there were two parts in the guide system. One part was about the aptitude test, consisted of seven subtests: verbal reasoning, spatial imagining, mathematic reasoning, computer capacity, abstract reasoning, physical knowledge, and sentence recomposing. The other part was about the career interest test, including eight aspects: career longing, curriculum desire, entertainment after school, activity preference, job preference, work environment preference, self-estimate of one\'s abilities, and discuss future with someone else. After three times modification and testing, the psychometric indices of the guide system were become well and stable.
