About every professional license accreditation has continuing education requirements and being a Certified Public Accountant is no different.
I'm currently working on a self study (pretty popular during Covid-19 times) 18 hour course. The only way I can drag my way through this thing is by splitting it up in a few hours at a time and with a supply of chocolate.
Yes, I'm retired, but I'm keeping my license current (for some crazy reason!) Maybe I can get the course finished today.
