That's the entire point of charter schools like this STEM school. They don't confirm to state standards in order to provide an alternative education for kids who just don't fit in or learn well at normal public schools.
Unfortunately, the state and liberal county school boards are incredibly hostile towards charter schools. They HATE the fact that charter schools don't follow the government education model. Don't count on seeing many more "alternative" schools in Colorado. The state board just shutdown an application for one in the Boulder area for no reason at all.
