are charter schools smarter schools?

I am just starting to write my second essay, which I chose to write about charter schools. I wasn't quite sure what my stance would be but I knew I wanted to show just how good some charter schools are. I had the opportunity to interview my sons' principal this past week, I was blown away with just how much work goes into starting up a new charter school. I was really impressed with just how dedicated the administration was to helping the students succeed in school and life. I was always against charter schools but the more that I research the school my boys attend and also the surrounding school districts, I would much rather send my boys to their charter school. Everyone has different experiences with charter schools, what's yours?
