The current study aimed to identify the level of language and math skills among deaf people who completed secondary education and compare them with those of hearing people in the school stage from the second to the seventh grade. To achieve the objectives of the study, two tests were designed, the first for linguistic skills (written expression and reading comprehension) and the second for math skills (math operations). Basic, first-degree equations (volume, area, angles, and units). Validity implications were extracted using content validity and discriminant validity of the two tests, as the two tests were able to distinguish between the age levels of the participants (by grade) and distinguish between hearing students and deaf students. Reliability coefficients also extracted using Cronbach's Alpha. The study conducted to a purposive sample of 155 people, including 45 deaf people who completed high school and 110 hearing people from grades 2-7 of both gender (male & female). The results showed that the level of deaf people in language skills is equivalent to students in the second grade, and that their level in math skills is equivalent to the fifth grade. The results also indicated that there is a statistically significant difference in language skills among deaf people in favor of females, and that there are no statistically significant differences in the level of math skills among deaf people according to the gender variable.
