It is important first to emphasize that EMDR and TFT are not related. The approaches and results should not be confused. Before you attempt to incorporate anything in the school system I suggest you first make sure it is appropriate to do so. Children cannot give informed consent.
EMDR should be used only by licensed mental health professionals. It has been well researched and the clinical parameters are clear. There are currently three books describing the use of EMDR with children which I have listed under the headings EMDR and ADHD. Any of the authors can be excellent mentors. However, once again, do not assume that EMDR's research base supports anything but EMDR. There has been an unfortunate amount of misinformation bandied about on the internet that has caused disparate approaches to be confused.
