The state, if you recall, released a snapshot of student performance in Milwaukee’s school choice program last week. Tony Evers, head of the Department of Public Instruction, used the numbers to make a political statement against school choice, which he opposes.

But the figures had issues, and now still more are emerging. One of the surprises in the figures were how poorly one particular choice school, Tamarack Waldorf, did.

It’s surprising because Tamarack is by reputation a good school, unusually deliberate in its curriculum and rigorous in the peculiar way of schools in the Waldorf movement – where, for instance, children do not just have a chapter on photosynthesis but, instead, spend a couple of weeks learning the chemistry behind it and studying the geometry of branches and doing a project on forest ecology and reading literature about trees and taking a field trip to the park, the better to appreciate art involving trees and to make some of their own. Rather than taking tests, the children produce books to demonstrate their learning.

The kind of people who send their kids to such a school are generally engaged and intellectual parents – and, generally, not favorably disposed to standardized testing.

So an unusual number of Tamarack parents opted their children out of the state’s tests, as is the right of any parent in the state. You can see the figures here: In math and reading, about 55% of choice students at Tamarack didn’t take the state tests.

The state’s figures say that 42% of Tamarack students did well – scored “proficient” or “advanced” in reading, and 24% did in math. Those aren’t good scores. But they aren’t real, either.

As Tamarack administrator Jean Kacanek wrote to parents, “The data published is not complete because the Department of Public Instruction averaged scores of ‘0’ for each MPCP student in grades 4-8 at Tamarack who did not take the test. As one might expect for a Waldorf school, with a philosophy averse to standardized testing, many parents chose to opt out of the test.”
