obtained. Alphabets, abugidas, abjads, and syllabaries all seem to require the reader/writer to know something about the phonology of their target language prior to learning the system. Profoundly deaf children do not have access to the same auditory base that hearing children do. Orally trained deaf children do not always use phonological information in reading tasks, word recognition tasks or homophonic tasks; however, deaf signers who are not orally trained do utilize phonological information in word-rhyming tasks. Furthermore, when performing on tasks with phonologically confusable initial sounds, hearing readers made more errors than deaf readers. Yet when given sentences that are sublexically confusable when translated into ASL, deaf readers made more errors than hearing readers. The body of literature clearly shows that skilled deaf readers can employ phonological skills, even if they don't all the time; without additional longitudinal studies it is uncertain if a profoundly deaf person must know something about the phonology of the target language to become a skilled reader (less than 75% of the deaf population) or if by becoming a skilled reader a deaf person learns how to employ phonological skills of the target language. Pedagogical challenges for sign–print bilinguals In 2012, "About one in five deaf students who graduate from high school have reading skills at or below the second grade level; about one in three deaf students who graduate from high school have reading skills between the second and fourth grade level. Compared to deaf students, hard of hearing students (i.e., those with mild to moderate hearing loss) fare better overall, but even mild hearing losses can create significant challenges for developing reading skills". These concerning numbers are generally the result of varying levels of early language exposure. Most deaf children are born to hearing parents, which usually leaves a deficiency in their language exposure and development compared to children and parents who use the same modality to communicate. This group of children acquire a wide range of proficiency in a first language, which then impacts their ability to become proficient in a second (though sometimes possibly a first) language in the written modality. Children exposed to Manually Coded English (MCE) as their primary form of communication show lower literary levels than their ASL signing peers. However, in countries such as Sweden which have adopted a bilingual–bicultural policy in their schools for the deaf, one sees a higher literacy rate compared to school
