The present situation of distant learning in a hands on training become very difficult for an instructor to evaluate a student. Let us take for example, simple first aid training, Though you may indicate where to locate a pulse of  a client/ victim, you not been in the working space provides a difficult form of assessing student. Though he/she may say yes the found the pulse you cannot effectively evaluate. This is most difficult for the newer trainees in any hands on training. It would end up delaying and prolonging training taking it out of the time frame allotted for a set module.
