The Seattle Times editorial board states the obvious while obfuscating the facts:
But here's something for voters to consider: the charter schools outperforming public schools share a common strength: parent involvement in the classroom and in leadership.
And here's something else for voters to consider: more than twice as many charter schools underperform public schools than outperform them! At least according to the same peer reviewed study the Seattle Times has seen fit to (deceptively) cite in the past.
As for parental involvement, well of course that's a critical ingredient in the success of all schools, public, private, or charter. That and ample funding. So I hardly see parental involvement as an argument for approving charters.
