This raises a lot of questions for someone from Europe.
If a school is completely private and does not follow a standardized educational program, how can it be considered a valid education? How can you apply to college with it? Do the schools just have some sort of nudge nudge deals with each other?
How far up in your studies can this go? Can a college or university have privately set goals on what is required to become a bachelor, master or a doctor*? Or is this the reason why which school you got your degree from is such a big deal over there?
(*More importantly, could I set up a private school and declare myself a Bachelor of Awesome Sciences?)
As another person from Europe, I have more questions. The standard for what kids need to learn to maintain accreditation - does this really not include knowledge in natural sciences, geology, biology, genetics, etc?
Also, can you get into every college / university you want to with an education lacking these subjects or do some universities not accept people from private, Christian schools?
