My ex-wife intends 2 put our son in a Mennonite school. Will this doom his education? Can I legally intervene?

We separated after our son was conceived two years ago. Since then she has gone from an ex-stripper to a fanatic Mennonite. She plans on moving to Scurry, TX and enrolling my son in a Mennonite School called Grays Prairie Mennonite School, which I can't find a trace of on Google. My understanding is that Mennonites place little value on education and the school likely lacks any accreditations or licensed, qualified teachers, and typically peaks at an 8th grade level. If the Mennonite Education Agency is any type of standard, then this school isn't even a member of that. My fear is that he will not only receive a pathetic education and not excel in the real world when he inevitably leaves Mennonites as soon as he's old enough, but also that REAL universities will view him as an illiterate hooplehead. Does anyone have actual knowledge of Mennonite education? What are my legal rights as his father in determining his education methods? I am fearful for my son and his future. Please help
