Having absolutely no logic to defend their position:

With a 90-day deadline on negotiations with the teachers union having passed, Chicago Public Schools can implement a teacher evaluation system that will see student performance count for 25 percent of an elementary school teacher’s assessment, a figure that will rise to 40 percent in five years.

The Chicago Teachers Union has opposed such significant weight on student performance, but even at its highest the CPS proposal for student performance is less than the 50 percent used in states such as Colorado, Tennessee and Ohio.

So we’re still going to be behind other states, but yet CTU is still fighting it:

“We don’t disagree on every aspect, but we don’t agree on the plan as a whole,” said CTU’s lead negotiator, Carol Caref.  Currently, teachers are evaluated using a checklist that both principals and teachers have called useless.

I see, the current system sucks and everyone knows it’s worthless but whatever you do, don’t include student performance in any new evaluation method.

Caref said the union thinks having student performance count for 40 percent is too high because of concerns about the test data’s reliability. He said the union believes it’s a mistake to implement a new evaluation system without first trying it on a pilot basis to identify any problems.

Ya, problems like it may show that teachers that suck have been given the green light to continue to not educate children year after year after year.  That would be a problem for the Union.

Big win for the children though.

CTU can’t die soon enough.  CPS has completely failed generations of students nearly entirely as a result of CTU pushing it’s significant weight around.  Can’t evaluate teachers… shear nonsense.

CPS lost it’s moral imperative years ago.  We as a people owe it to our children to build a competitive network of schools which give parents a real choice — a voice — in their children’s education.

If we’re really all in this together, then All Schools are Public Schools.
