Regularly scheduled: scheduled monthly and publicized over WWW, global emails and flyers. (Show WWW page of current month’s offerings - can emphasize class descriptions, important notice etc.)
These are more difficult to teach and plan - don’t know who or how many will show up for a given class.
On-request: encouraged. Easier to plan for and usually are teaching a group of similar skill level.
Specialized: as a subset of a larger meeting/conference; for example, Dept. of Medicine’s Family Medicine Update meeting.
Note:
Sessions are typically 1.5 to 2 hours in length but classes are tailored in time and content to meet the specific needs of any group.
