There will be a committee I am sure. That is the way it is these days and that is a good thing. I am sure the JH principal, HS principal, a couple of teachers, maybe a coach from another sport, personnel dir., and then maybe a community member. They will go through the resumes and discard all the ones that do not meet the minimum requirements. Then go through them again and pick out the best ones. Then set up interviews. Then pick 3-5 for the Supt. to look at then all sit down and decide who they want to hire. That is the way it is and the way it should be. One person does not make the hire and a group of people who have no business in the school will not make the decision. The AD is an important administrative position in the school and that hire affects a lot of people in the school from counselors who are trying to schedule athletic periods to principals trying to get coaches in the athletic period. There will be new people coming in for sure.
If you want a good head coach / AD, be prepared to meet demands like all coaches in the athletic periods and the coordinators in both athletic periods. 2 conference periods for the coordinators and no second sports for the coordinators. That is the way it is in your bigger schools. That way, you can bring in good, solid, wxperienced guys and maybe bring in people from more successful programs. You have to sweeten the deal so to say.
