NOt every student who signs is actually given a American Sign Language. There are various forms of signed English (not unique and/or full languages like ASL, but rather a variant of English). Many parents have been advised to not allow their child to use ASL. Even those who do choose to sign often use signed English because ignorant professionals say it will help them with their spoken and written English (which ASL actually supports better).

These statements are not incorrect. There is an abundance of research that has been done that validates every single one of these for a large population of Deaf/Hh students, whether they identify as Deaf or just as having a hearing loss. Academically, the majority of Deaf students do have language deficiencies. They are lacking language skills and this has been measured numerous times by those who support the use of ASL and those who oppose it–especially written language skills. Even students who do sign often show deficiencies in ASL since only approx 15% of Deaf children are given ASL from birth, and only 10% are given it from native users who are themselves proficient in ASL. The article specifically says make sure you use appropriate interpretation services. It does not say providing such services is bad. Research also does show that a large amount of Deaf students are uncomfortable in mainstream schools socially and emotionally. At no point does this article state ALL or even MOST Deaf/Hh students. These statements are indeed accurate and backed by evidence. Using different words like “differences” not only hides the facts, but alters them.

there are many sign language why would he mention only American Sign language that article is for all not just Americans
