The rollout of the Common Core standards was accompanied by the arrival of online testing. The dream of corporate reformers is a seamless standardized system that allows comparison of every student to age mates across the nation.

 

The dream has encountered some obstacles, however, which Emma Brown reports here in the Washington Post.

 

In some states, like Alaska, Kansas, and Tennessee, the breakdowns were serious. Alaska canceled this year’s testing.

 

Presumably, over time, the glitches will disappear and every child will see exactly the same questions and have a chance to choose the same answers (depending on whether there are one, two or three national test vendors).

 

What then? We will be able to compare schools, districts, states, and students. What then? The tests have no diagnostic value. What will we learn from the millions or billions invested I national testing that we have not already learned from NAEP?
