AAC Performance Report

The AAC Performance Report is a set of 17 quantitative summary measures of communication performance using AAC. The Performance Report supports AAC evidence-based practice. It can be used for various purposes in the AAC intervention process:

1) To guide the assessment process,

2) To enhance the funding request,

3) To guide and monitor AAC therapy, and

4) To measure outcomes.

The AAC Performance Report is based on language samples collected automatically using language activity monitoring (LAM). LAM and other logfile recording functions are free features included in modern high performance AAC systems available from various AAC manufacturers. U-LAM (Universal Language Activity Monitoring) is software that allows a PC to act as a language activity monitor for use with older AAC systems that do not include LAM.

The following is an example of the LAM record of the AAC system events leading up to a single utterance: 

"It’s faster than spelling everything out which is what I used to do "

16:26:05 SEM "It's "
16:26:08 SEM "faster "
16:26:14 SEM "than "
16:26:41 SPE "sp"
16:26:42 SPE "e"

The AAC Performance Report can be easily generated from LAM data using PeRT (Performance Report Tool).

The AAC Performance Report is the subject of an AAC Institute Self-Study Program course. For each of the summary measures, there is a definition, method of computation, and clinical use.
