TAKS and the new STARR

I've recently been given the privilege of helping my supervising counselor organize all the materials for the TAKS testing we've had and will have soon.  I like the organizational part of it, but I have concerns about how will I know all the "rules".  My counselor spends a lot of time reading all of the manuals very closely to make sure she gets it all right.  I think the main part of this minor stress is that I envision becoming a counselor in a small rural school where I would be the only counselor, so I worry about getting all the materials out and staff trained leading to a successful administration of the test when I might not have a mentor.  I almost want to be a counselor in a slightly larger district where I might have more tips and pointers from someone who has done this several times already.  Anyhow, I know it will all work out, and that I am perfectly capable of figuring it all out, but it is overwhelming to see all that's involved as I've been allowed to help out.
