This hierarchy is intended to help clinicians choose appropriate language skills to target with Deaf students with language deprivation. There are no ages or grade levels, as it is meant to match the student's current language abilities. It is also meant to be language-agnostic so that it can be used in oral or signed language as a guide for goal writing and activity planning. However, skills should be targeted in American Sign Language (ASL) first. If a Deaf child already has language deprivation, they need intensive language treatment in a fully accessible language (i.e., ASL). Clinicians should not begin to introduce printed English (aside from letters) until the child is at Level 2. Both printable and digital/fillable forms are included.
