I do not know which schools you are talking about, but having attended school, there were times when students were in the back room studying and taking tests while others were being treated. Hours were being tracked, and students needed to have so many hours before they could progress off of arms and legs and onto facial areas.
For those near Long Beach, California... American Institute of Education is in my opinion a very good place to save money on the cost of electrolysis. What others may not realize, is that the school does also have a classroom via another entrance next door that is also utilized..
Having electrolysis by senior students however, I believe is a little more costly than just having any student perform the electrolysis.
