The Illinois Education Association (IEA) has always leaned more Republican than its Illinois Federation of Teachers counterpart, but the IEA's endorsement of one GOP candidate raised a few eyebrows this year.

Conservative state Representative Dwight Kay (R-Glen Carbon) was endorsed by the IEA last month. The Illinois AFL-CIO assigns the Metro East legislator a rating of 36 percent so far this session. The Illinois Federation of Teachers, which is affiliated with the AFL-CIO, endorsed Kay's Democratic opponent, Cullen L. Cullen. The IEA is not an AFL-CIO union.

The Kay endorsement is not what you'd call an everyday occurrence. Yes, the IEA endorses a fair number of Republicans, but it's well-documented that Kay was on friendly terms with the Tea Party when he was first elected in 2010, and the IEA is not enamored with that bunch.

Education reform in Illinois features two major storylines: politics and policy. On the political front, two powerful forces - the business community and teacher unions - have competing proposals. On the policy end of things, the primary educational question is whether and to what degree teacher performance will be a factor in school-district workforce decisions, from budget-related layoffs to dismissals to tenure.

As the law stands now, layoffs and tenure are simply functions of teachers' years of service and don't take into account whether students are actually learning. Firing a tenured teacher is time-consuming and costly, and the current teacher-evaluation system, all sides agree, is ineffective. Common-sense reform is long overdue.

Given Illinois' history and reputation, however, one might expect politics to dictate the outcome at the expense of sound policy. Somewhat surprisingly, the substance of the different proposals appears to be getting a careful vetting, and politics have thus far taken a back seat.
