The campaign by teachers unions to block common sense school reform has made its way to Jefferson County, Colorado, triggering an education policy fight with national implications. Board members there who are standing up for what is right deserve the support of conservatives as they face traditional labor intimidation tactics and media blowback.

Here’s what’s happening: Earlier this month in Jefferson County — one of the largest school systems in the country with 85,000 students — a newly elected school board voted to set up a new performance-based compensation package for teachers. It also proposed setting up a 10-member review committee that would advise the board on different curricula, including the Advanced Placement U.S. History Course known as APUSH, which after a recent rewrite, has become controversial.
