BASIS Charter Schools educate students at an internationally competitive level, with BASIS students ready to compete with their top-performing peers in Finland, Korea, or China. BASIS Tucson North and BASIS Scottsdale fifteen-year-old students proved this in their 2012 results on the OECD Test For Schools. These results place the BASIS Model above the acclaimed Finnish and Korean education systems, and on par with Shanghai, the world’s best.

My interested is piqued !
