How to Select an AAC System

In this module, we will discuss different AAC systems and the process of assessing and selecting AAC systems to support communication in individuals with complex communication needs (CCN).  

Selecting an AAC system may involve several components and considerations to ensure the system selected meets the needs of the individual.  

The three main goals of this module relate to important aspects of selecting an appropriate AAC system for the person using it. 

Goal 1:
Outline and define the categories of AAC (unaided and aided, with low-technology and  high technology). 

Goal 2: 

Discuss the type of assessment that can be used by practitioners and whānau to make decisions regarding AAC types.  

This includes direct and indirect assessment physical and mental assessment of the person the  AAC is for; and questions that the whānau or practitioners can be asked. 

Goal 3:  

 Outline areas of consideration. Including;  

1. Individual characteristics; strengths, preferences, needs and goals 

2. Device characteristics; physical, technical experience, practicality and reliability.  

3. Family, whānau and community values, circumstances and engagement;

“Communication Partners”

Who is involved?  

As a key goal for many individuals using AAC is to enhance their ability to make connections, build community and communicate their wants and needs, the system must also meet the needs of the social network and community the individual has.        

There will likely be several groups of people working collaboratively to make this decision: 

• The individuals' close and/or extended family/ whānau should be involved and considered. 

• The communities and educational institutions that the individual frequents.   

• A practitioner or team of professionals. 

• The individual that the AAC system is for will be at the centre of this decision-making progress. They may take an active or passive role in the decision making, depending on their age, developmental stage, ability or other factors.
