To ensure the most effective use of resources, time and costs involved with conducting service school limits on the minimum and maximum numbers of persons attending have been set. The minimum number of persons attending service school is six (6) and the maximum number is twelve (12). Benefits of this are the enhancement of training through the sharing of knowledge and experience as well as ensuring ample time is available for detailed training on topics of interest to the class as a whole. Service schools are held three times a year and every effort is made to meet the minimum attendance requirement. In the event the minimum attendance requirement is not met, the persons scheduled to attend the course will be notified via phone and/or email of course cancellation. Based on this criterion, the decision to cancel the course will be made three weeks prior to the scheduled course date. (No reimbursement for plane tickets.)
