Class is the main place for peer interaction. The goals of this study were to explore the characteristics and the construction of friendship network of children with hearing impairment in class and its dynamic development, and we also researched on the relationship between status in friendship network and personal feature (appearance、intelligence、academic achievement). In this study, we used peer nomination to define the friendship network, and peer nomination rank and assignment for the scores of appearance, Raven intelligence test for intelligence. Our sample consisted of 13 students with hearing impairment, from an oral class and a sign language class of a Deaf school in Shanghai. It is a 2-year longitudinal study, which was tested once a term. In the first test, there were 3 girls and 10 boys, with the average age 10.8(SD=2.45). The result shows that in the early third grade, the individual network center degree of student with hearing impairment has highly significant relevance with appearance(r=.684, p<0.01), academic achievement(r=.593, p<0.01) and age(r=.671, p<0.05). But this relevance fades with the grade rise. Until the fourth grade friendship network centrality are not significantly related with the factors. There is a stable small group in friendship network of student with hearing impairment, whose members are in the center of the friendship network. The mutual choose friendship of students with hearing impairment in the class has medium degree stability, among which the four times and three times mutual choice account for 45.2% of the total number.
