Charter vs. Public Schools

An interesting study from the U. S. Department of Education. In spite of the alternative charter schools provide in states with really dismal public school systems (like my old home state of Arizona), I've always had serious reservations about this idea for two reasons: (1) They suck money from other public schools, often the ones with the worst problems with funding, dropouts, etc., and (2) Many restrict teachers' rights to join unions. This article only adds to my concerns.
