Hi all,
Thanks to everyone for the great responses. It seems that Reiki for the individual student would best take place in a one-on-one counselling/therapy session where parental consent has been given.
However, Reiki, would be very helpful for a teacher or para to use for his/herself for stress and as a classroom management tool (pehaps someone else could think of a better phrase.)
There is always, though the passive use of Reiki. Reiki flows if the situation needs it without any intention of giving Reiki. Reiki is held by objects. Giving Reiki to a desk of a child that is anxious would probably make some difference.
Thanks again for all the great comments!
