Upon completion of some brief, informal research I have honored your request. Some of the job titles are a bit dicey as they seem to have varying titles by district and I am not sure if that comes from the state level.
Protecting the individuals themselves, though you can easily do the same research on your own time, I can tell you that it appeared that "many" teachers have some sort of administration label to their job title but when cross checking the DOE website it gets a bit confusing.
Knowing what I know about the top of the pay scale in many districts, it is also head scratching in that area but I will not speculate.
What I CAN tell you upon some research is that the "average" head coach in each of what most would consider the "Power 4" conferences made the following amount in 2019 (the last year data was published).
Metropolitan Interscholastic Conference: $103k
Hoosier Crossroads Conference: $82k
Duneland Athletic Conference: $78k
Summit Athletic Conference: $67k
One could make a case for the SIAC/Conference Indiana but I am sure they are comparable.
Draw your own conclusions.
