How Many Trainers Do You Need?
When you decide how many trainers will be required for your courses, you have to make an estimate of the work load each trainer can handle.
The factors you have to take into account are:
the number of courses,
the duration of the courses,
face-to-face ratio (the amount of time a trainer spends in front of a class),
the number of trainers needed to run each course,
how much time is spent in preparing courses,
how much time is spent in developing courses,
how much time is spent in other activities such as planning, supervising and evaluating,
the learning curve of new trainers.
