Why Private Schools Imitate State Schools

A mystery:

Given the state of the state run schools, why do Christian schools imitate the failing state system and approaches?

Suggestions:

• Certification of teachers through NCATE
• Control of assessment tools by Progressives
• Financing
• Private schools distinuguish the teaching and curriculum from the governance, thus imitating the former
• Reputation by quantity (i.e. they’re big so we should be like them)

What do you think explains this, to my way of thinking, rather odd fact?
