Pros
Great, well-thought-out curriculum fo English/History in particular. The students, if a bit robotic because they haven't been taught to question authority, are wonderfully well behaved.
Cons
What they don't tell you, as other reviewers have intimated, is that a cadre of conservative Christian men run this organization, and this organization is essentially a thinly veiled parochial school that doesn't have the money to go private. Great Hearts claims to want liberal arts graduates generally when recruiting teachers, but oddly, almost all of the recruits come from Evangelical liberal arts colleges, e.g. Grove City, Biola... This seems like an odd coincidence... As another reviewer has suggested, if you're not Christian and don't come from a socially conservative environment, prepare for culture shock. The organization is much more conservative than Arizona/Phoenix generally. By way of example, it was a SCHOOL CRISIS when two middle schoolers made out at a dance. Obviously, this isn't acceptable behavior... but it's not something that should create bomb-threat like hysteria because it affects your sense of sexual morality.
