The best way to cure this problem is to get out and visit other charter schools! This applies to governing board members, principals, business managers, curriculum directors, teachers, and simply: everyone!
One of the best parts of my job is that I have been to almost every charter school in the state and get to see the incredible things happening at these schools. A lot of what I do is spread the word to others who may be struggling in a particular area or need an idea for how to handle a situation. Many of these best practices are on the CDE website: either in the eguidebook of best practices, the administrator's handbook, or the governing board training modules. The charter school community is very open to sharing, without reservation, and so there is an ideal climate for gaining from each other's experiences.
