You probably have already thought of a dozen more tasks. If you ignore or minimize the importance of such items, you risk starting your training classes on a sour note. That's not good customer service. Attending to such minutiae may seem inconsequential compared with the big-picture mission of your organization. But the detailed process of administering training can easily bog down your department and tie up resources.
Good records ease the logistics by ensuring standardization and continuity.
It's also important to document any contingency plans in the event that things don't go as planned. There are several good commercial programs available to track your training. They vary from overly simple roster programs for a few hundred dollars to highly sophisticated client-server applications costing tens of thousands of dollars. Choosing the right one for you takes planning and research. For the adventurous on a tight budget, try working with spreadsheets or simple databases such as Microsoft Access.
