I see. I just thought 19 months was way over the top.
For the context of PT Practice, I completed the Alliance self study module. It used to be that you can request to complete this once the Alliance has a file and a PIN number for you. I hope this is still the case. To do this, you need to contact the client service administrator by email and indicate your interest to complete the module while your credentialing is ongoing. She'll send you the module options and application form. Once you chose the Alliance module on the option list and send in your application form and fee, the module material will be sent to you by post. It is a simple and straight forward module to read. I think it took me two evenings to complete it. There is a declaration form that you need to send to the Alliance once you have read the module, you will need to complete and take to a notary public to attest. Your credentialing officer will send you an email confirming that you have met the requirement about 4 weeks after you send in the declaration form.
Hope this helps.
