Our courses All courses Is there a minimum attendance requirement? All of our courses require a minimum attendance of 85% in order to complete and receive a completion certificate. This is in line with colleges and places of further education. As our courses are of different lengths, this equates to a different number of days that can be missed on each course. For example, Psychology for Change is 16 days long which means it is possible to miss a total of 2.5 days.
