[Dysphagia] dysphagia specialist

[mbuckie at dmc.org (Buckie,Marcia)]

In an attempt to redirect the qualifications thread, I am wondering if the proposed "dysphagia specialist" could be similar to that of a Certified Hand Therapist. For those of you not familiar with it, a CHT can be a PT or OT, but needs to take a board exam to become a CHT. In my geographic region, CHT are usually OTs, but I am not sure why.
 
I am not familiar with the actual governing body that presides over the credentialing, but it seems as if this could be an eventual solution to quality control in the provision of dysphagia services. ASHA now has the Board Certification, and from what it looks like, the AOTA has its own version, but how do we know that they are interchangeable and/or comparable?
