What I will say is that any comparison of the Iowa Core to the Common Core is not an apples-to-apples comparison. The Iowa Core is not standards and benchmarks and has never pretended to be.

Clear achievement targets or criteria for success are provided to students and parents in student friendly language before instruction begins. Doing so informs students what is expected of them upfront. Imagine how difficult it would be for a young person to build a log cabin for the first time without a picture, and then get graded on how similar their log home is to the picture they did not get to see. That would not be fair. However, providing clear achievement targets to students and parents before instruction begins can be a very efficient, effective, equitable formative assessment strategy.

The first barrier is even having the option to test out of units in the first place.

When we discuss the Iowa Core, this is an example of what we need to do. Get rid of the rest of that stuff. Determine what is important. And then have a deeper lesson, leading to deeper conceptual and procedural knowledge, with authentic and formative assessment. Which will lead to permanent learning.
