This document presents the Assessment of Deafblind Access to Manual Language Systems (ADAMLS), a resource for educational teams who are responsible for developing appropriate adaptations and strategies for children who are deafblind who are candidates for learning manual language systems. The assessment tool should be used for all children with a dual vision and hearing sensory loss (deafblindness) in educational settings that use a form of manual communication. Communication is the means by which a child gains access to the curriculum and to education generally. Therefore, if there is a breakdown in this critical exchange, the child is essentially denied the right to a free and appropriate education. It is hoped that the ADAMLS provides unique and important information in a user-friendly manner to fulfill a need that exists in the field of deafblindness. A bibliography is included. (Contains 61 illustrations and lists 11 resources.)
