Someone sent me a flyer for this K-12 self-paced, individualized, distributed learning program that is free (virtual public school) to BC, Canada residents (tuitioned version also available for those outside BC). I don't know anything about it from personal experience, but the concept looks intriguing, especially its self-directed, reflective, integrated nature. It has an unschooling vibe to it, but with provincial learning standards and funding supports attached.

Thanks aeh! Worth looking into.
