One simple question should resolve the "school choice" issue for most thoughtful people: "Who is in a better position to decide how and where children can best be educated: their parents or the government?"
The answer should be transparent, so why not actually allow parents to make those important decisions?
Recently there were headlines that the Los Angeles Unified School District has (finally) agreed to measure a school's success at raising its students' performance. But if parents could choose the school that their children could attend, no other rating system would be required.
Simply stated, if parents felt that their child's school was not doing as effective a job as another school within their area, they would move their child to the better performing school.
