"You'd need to define "educational".

Because of my education in head-shrinking, I can spot various mental problems quite readily, but I'd like to know how to tell when Satanm aliosque spiritus malignos are present.

Funny you should say that. A lot of exorcists are psychiatrists, actually. All other explainations have to be ruled out before exorcism begins. Every account I've read, though, says that the possessed recoil at the sacred. They spit at a Crucifix or Holy Water, won't go near a church and utterly hate them. No two cases are the same, but that is the one thing they all have in common - hatred for the blessed. Beyond that, you can't make up some of this stuff.
