Course description

Over 14 lessons, the course teaches participants how to carry out the Buffalo Model diagnostic procedure.  This enables audiologists to effectively diagnose the characteristics of a client's specific auditory processing disorder.

The Evaluate APD Master Course is completed online, on-demand. This means participants can learn at their own convenience.

The Buffalo Model is a coherent approach to the evaluation and remediation of APD.  Buffalo Model testing procedures, the Central Test Battery (CTB), have been used with great success for more than fifty years.

The CTB includes the Staggered Spondaic Word (SSW) test, the Phonemic Synthesis (PS) test and the Speech in Noise test.  The Speech in Noise test is an important indicator of the Tolerance-Fading Memory (TFM) category of APD, as well as a practical clinical measure.

This battery of central tests contains many indicators of APD; however, administration of all three tests generally requires only 45 minutes.

Once the characteristics of a client's specific APD challenges are diagnosed - using the Buffalo Model - professionals can begin create a customized training program to improve clients' areas of difficulty. Training exercises such as the Phoneme Training Program are taught in the Treat APD Master Course.

By completing the Evaluate APD Master Course, participants will learn to use the Buffalo Model testing battery in their own audiology practice. Knowledge of and application of the Buffalo Model improves the service that professionals can offer their clients.

Don't Just Take Our Word For It


I’ve started the course work full capacity today and “mind blown”. every word just fits so well in what I’ve been thinking for ages. It’s such a relief and I’m annoyed with myself that it has taken me this long to move in this direction. I’m so grateful to you.

Riette Schwass, Audiologist


 I like how they were broken up into a series of short videos rather than one long one. Good stuff Angela.

Tom Goyne, Doctor of Audiology


Happy Thanksgiving! I'm so thankful for the way you share your knowledge. It's made me more confident in recommending aural rehab and carrying it out. My first little patient has made unbelievable strides and I have 2 more getting ready to start.

Melissa Wilson Karp, Doctor of Audiology


I have never seen APD from this perspective; it has given me valuable insight!

Tanvi Sathe, Audiologist


I hereby give consent to Angela Loucks Alexander, Audiologist, at Auditory Processing Institute to record our diagnostic and therapy sessions.  

These recordings will be used to gain further understanding of important aspects of the treatment and to train allied professionals work with Auditory Processing Disorder.  I have discussed this procedure with the Audiologist.

I will be consulted if any of these recordings will be used for public use (i.e., documentaries or podcasts).
