Here's a start:
Tempe Preparatory Academy in Tempe, Arizona. 7-12.
Ridgeview Classical Schools. K-12. Core knowledge (ala E.D. Hirsch) in elementary school; classical liberal curriculum in upper grades. Located in Fort Collins.
Liberty Common School. K-12. http://www.libertycommon.org/home/index.htmArrupe Jesuit High School. 9-12. They advertise an affordable college preparatory education via a unique corporate sponsored work study program. With big bucks we could have a private school instead of a charter. I don't know what underlies their pedagogical approach.
Denver Arts and Technology Academy (DATA). I include this one because it's run by educational management organization (EMO). According to Colorado Charter School law, schools can be affiliated with a for-profit or non-profit EMO. In addition, their "high tech" emphasis is something that costs big bucks. If I get my way, our school will be decidely "low tech" with an emphasis on the written word. http://www.denveratacademy.org/
St. John's College. A college? Take a look at some of the methods they are using. Some things might be adaptable for our context. I'm intriguiged by their "all courses required" approach.
