Wisconsin State Journal Editorial:

Wisconsin’s statewide test given to hundreds of thousands of students each year deserves a poor grade for its own performance.
The test has some of the weakest standards in the nation.
The test takes far too long to process.
The Wisconsin Knowledge and Concepts Examination also fails to compare student proficiency at the beginning of a school year with proficiency at the end of the same academic year.
All of that needs to change, as recommended last week in reports by the Wisconsin Policy Research Institute, a conservative study group in Hartland.
