I would like to say one of comment's in #39. There are many impacted some issue how to Deaf children's learning age and Deaf adult's learning age that is because they are not first language in English, they are first language in FSL who their experienced in domain such as cognitive,physical, emotion developments part of lifespans.

One thing is important is understands of Deaf peoples who have developed in languages. There are two difference BICS and CALP.
Basic Interpersonal Communication Skill are related language skills need in social situations the day to day language to interact socially with other peoples. English learners when BICS skills when they are on the playground, in the lunch or recces in activities.

Cognitive Academic Language Proficiency is related refer formal academic learning, such includes listen, reading, writing about subject area content material that where give level of language learning essential for student to success in school. Students need to time and support to become improve proficient in academic area.

These are classroom or social need to understand difference between in social language and academic language acquisition. They would have acquisition language.
