Augmentative and Alternative communication (Aac)

What is AAC?

According to the American Speech-Language Hearing Association (ASHA), AAC is a term that is used to describe the methods that we use to express ourselves, other than speaking. This includes using our bodies (i.e., unaided systems) such as facial expressions, body language, and sign language, as well as using a special tool or equipment (i.e., aided systems) such as writing, manual communication boards, and icon communication with vocal output. AAC includes low-tech, mid-tech, and high-tech tools. The goal of AAC is to allow an individual with complex communication needs the ability to effectively communicate with a variety of communication partners most efficiently.

Low Tech Devices

Low tech methods of communication do not include any electronics and do not require battery power.

Examples include manual communication boards, sign language

Mid Tech Devices

Mid tech methods of communication require batteries and can provide vocal output.

Examples include switches such as a Big Mac, static displays such as Go Talk, CheapTalk, the Logan ProxTalker

High Tech Devices

High tech methods of communication are electronic devices that allow for storage and retrieval of messages, frequently providing vocal output.

Examples include Unity on an Accent 1000, Words for Life on a PRiO, Speak for Yourself on a tablet

What is CIU 20's AAC Process?

CIU 20 speech-language therapists may complete AAC Processes for students who have significant expressive communication difficulties. This process determines if a student needs an AAC system, and if so, what system is the most appropriate to allow him or her to communicate with others. The AAC Process includes the following components:

Assessment: Various assessment tools along with input from the family, teacher, and related service providers are used to determine (1) the student's current academic, cognitive, behavioral, and language functioning, (2) if the student may be a candidate for an AAC system, and (3) which specific AAC systems should be trialed.
AAC System Trials: In order to comply with Pennsylvania insurance guidelines, a minimum of three AAC systems will be trialed for 6 week trial periods. AAC system trials may include low-tech, mid-tech, and/or high-tech systems.
AAC Recommendation: After the AAC system trials are completed, the speech-language therapist will make a final recommendation regarding the student's use of AAC. For example, the speech-language therapist may recommend purchasing an AAC system for the student's use or may recommend no AAC system be used at this time.
