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. Furthermore, the guide system was primarily launched into applying, with four typical case studies, the practicability and serviceability of the guide system was showed swiftly.The entrance guide system for junior high school students that was developed in this research was one-upping in the entrance guide field in China.
