Augmentative and Alternative Communication - (AAC)

At Tettenhall Wood School, we believe it is vital that all pupils have access to effective communication systems appropriate to their needs.  Many of our pupils use different ways to communicate their wants and needs. This is referred to as Augmentative and Alternative Communication or AAC.


AAC is split into three categories:

  1. Low Tech AAC

  2. Mid Tech AAC

  3. High Tech AAC.
