I am looking for any information you have related to middle school guidance counseling.  I am especially interested in anything showing positive results of having a counselor assigned to each grade (6-8).
 
I can't tell you how funny this is in a language you will relate to.  Our schools are so small here, that most districts have only one counselor for the whole K-12.  Those (a few in 15 counties) that have more than one, have zero or one for the middle school and one or two in the HS.
 
The best I can do is steer you to research, where you may find what you are looking for.  I recommend ERIC CASS at

Use your resources at your closest university library.  The research databases are incredible.
Sorry I don't have anything on hand that meets your need.  Good luck.
