Deaf children develop literacy skills through their first signed language (e.g. American Sign Language) in the same way English-speaking children develop literacy skills.
In order for deaf children to develop literacy skills in English as a second language, they must acquire their first language (ASL) from birth (or at the earliest possible) as a foundation before transfering knowledge and literacy to another language (English).
In the end, these Deaf children are adept in bilingual literacy (native in both languages or native in ASL and highly fluent in English).
