The purpose of this study was to investigate the current situation in sexual knowledge, sexual attitudes, and sexuality education need of the hearing-impaired students in the fifth and sixth grades.One hundred and nine participants (69 students from general elementary schools and 40 from three elementary schools for the deaf) were purposively selected for the study. Self-designed questionnaires were used to collect the data through analysis by descriptive statistics. T-test and one-way ANOVA analysis were further employed to obtain the data. The main findings were as follows: 1. The average percentage of the correct answers for sexual knowledge was 74.26%. Among the questions, the correct answer to “privacy” had the highest percentage (86.23%); sexually infected diseases, had the lowest percentage (64.83%). The main sources of their sex knowledge were teachers (55.00%) and parents (54.10%). 2. In sexual attitude, the score of “relationship with the opposite sex” was relatively high, in comparison to that of “homosexuality”. The higher the father’s education, the more positive his influence on the children. 3. In evaluating the needs for sexuality education, the results showed there was no significant difference among students' background variables. The findings reveal that students of hearing impairment from different schools have the same needs for sexuality education and gender education, which needs to be strengthened and improvised in schools and families. Some suggestions are given to educational administrative authorities, school administrative units, special education teachers and parents. Futher studies are recommended, too.
