Comparing different School Psychology Programs

[Schoolpsychforthekids]

So I am still in shock but I will have to choose between different programs within the area of School Psychology PhD. My future career goals are to pursue academia within a University possibly doing advocacy work/practice on the side. What are good "criteria" (I use loosely because the main factor is who I would like to do research with) to base programs on? I have all the information from interviews/website, but those who are in the field what is something you wished you asked or knew before choosing a program?
