Hand-holding at equestrian school?

I believe the answer is:

rein

(Other definitions for rein that I've seen before include "Restraint; strap attached to horse's bit" , "Hold back" , "Animal controller" , "Strap on a bridle" , "one's attached to a bit" .)

I've seen this clue in The New York Times.
