We accept mailed checks to pay for registrations for which the registrant has received an invoice. In order to register via mailed check, registrants MUST contact us (via phone, email, or web submission form) and request an invoice for the course that they wish to attend. On the course-event page, under the Register button, there is a button to "Request Invoice for this Course". You MUST receive an invoice from us with a confirmation number on it in order to be ensured a seat in the course.


Checks sent to us without a corresponding invoice will be automatically deposited, but this deposit does NOT guarantee a registrant's seat in a course. For complete details on paying and registering, see our terms and conditions of attendance.

Checks for open invoices may be sent to the Institute should be addressed to:
