Optician's Association of Massachusettes (OAM) Summer Health & Wellness ~ 3 credit conference

Today 3 New England opticianry school program directors convened at the Basketball Hall of Fame (amazing venue) providing ABO and NCLE credits to opticians on a very hot summer morning. Attendees earned credits after attending The Hygienic Optician by Maryann Santos (that's me) of Goodwin University, East Hartford, CT, Care of the Diabetic Contact Lens Patient by Dr. Aarlan Aceto of Middlesex Community College, Middletown, CT and Lifestyle Consulting for Your Visually Impaired Patients  by Blair Wong of Ben Franklin Institute, Boston, MA. I enjoyed listening to my colleagues speak on their topic of choice and I left learning something new.

The topics were well received by the attendees, as each topic generated some questions and conversation. There's something to be said about earning continuing education credits in chunks instead of the typical "all in one day" approach. 

From a learning standpoint, the message seems to get lost after three hours of instruction. I enjoyed observing how the attention span and interest level maintained an even keel at noon when the program was over.

What is your opinion on the length of CEC programs? Are you for One and Done-all credits in a day or weekend? Or is your preference having the courses spread out over the course of 2 or 3 programs throughout the year?
