Sign language is widely used by the deaf community or individuals with hearing impairment. Students with hearing impairment are also individuals who practice sign language to communicate. Hearing impairment students face communication barriers with their parents due to limitations in the use of sign language. The Epstein model is used as a guideline because it benefits hearing impairment students, parents, schools, and the community by improving academic performance, fostering good relationships, and raising awareness among parents and the community. The research instrument is a questionnaire aimed at obtaining quantitative data. Descriptive analysis is used to obtain mean values, standard deviations, frequencies, and percentages. The findings of the study show that the skill level and frequency of parents using sign language are at a moderate level. Continuous efforts are needed for parents to use sign language at an excellent level for the future of special education needs students with hearing impairments.
