Is one style of schooling the answer?

A question was asked to me by a friend: if we had education credits would it make a difference?

(education credits we are speaking about are from Illich concept of an alternative to the current public school's system. Instead of students getting one style of school, there are free credits to spend, and you get to pick your school)

My response:

I honestly think schools would start popping up because of the money to be made. This would also allow for specialist schools (example trade specific schools) in areas that have a high demand. I do believe the credit system would put pressure on the current system to change. If there were more options for people to choose, I believe the whole system would improve. If you really hated a certain type of school, you could choose a different style of school (public vs Montessori). 

When ever these debates around schools come up, I usually ask the same question.

If not everyone fits into "regular" society (we have institutions for different types of people or alternative living styles), how can we say that every student fits into the classroom? My point is a one size fits all is not the approach to achieving a student centered education is not working. We need a variance of schools and more alternative learning centers.
