Looking for the culprits behind tests’ dropping standards
What does it mean for tests to get easier? And is that really what happened to New York’s tests?
The analysis that has spurred that idea in the last few weeks actually found something slightly different. The tests aren’t necessarily easier, in the way that a kindergarten spelling bee is easier than the SAT. Instead, between 2007 and 2009, students who hadn’t learned much came out looking like they had.
This is an important distinction because it points to a different culprit behind the dropping standards than simply the individual test items themselves. Instead, Harvard professor Daniel Koretz – the lead author of the analysis commissioned by the state education department — names two possible causes: a phenomenon called “score inflation” and a possible psychometric error tied to an obscure state law.
The actual questions on the test play a role in both, but just as important is the practice of prepping students extensively for tests. Another key is a state law that forces New York to release all test items publicly, making it easier for teachers to practice test prep and making it harder for officials to keep tests consistent over time.
