 Basis schools seek to prepare students, in the elementary through high school level, to be competitive globally.This is done through extended homework hours, lecture driven classes, an emphasis on success in standardized tests, like Advanced Placement tests, and an opportunity to graduate early or complete a senior project.The first Basis Charter School, Basis Tucson, was founded in Tucson in 1998 by Michael and Olga Block, with the goal of educating students at an internationally competitive level.
