This article selected 7 high schools from 5 districts of Shanghai, asked 165 participates of international students who studied in local class to fill in cross-cultural adaptation scale for international students in local high school (CCAS-ISLHS). This scale refers to cross-cultural adaptation scales and acculturation inventories of Cross-cultural Adjustment Scale (CCAS), Acculturation Attitude Scale (AAS), Sociocultural Adaptation Scale (SCAS), Acculturation Rating Scale for Mexican Americans (ARSMA), and Suinn-Lew Asian Self-Identity Acculturation Scale (SL-ASIA). CCAS-ISLHS contains 30 items as: academic adaption (item=8), campus adaptation (item=9), language preference (item=6), self-adjustment (item=7), thus forming the 4 dimensions of the whole test. Structural Equation Modeling (SEM) was conducted by using Amos 17.0 to test the relationships among variables. The specified model had certain goodness of fit ([lambda]2 (4) = 114.209, p< 0.05, GFI = 0.78, RMSEA = 0.301, SRMR =0.194). The correlations of variables can be analysed through daily practice and accumulated experience in the school field.
