Miracle schools, vouchers and all that educational flim-flam

ASK THIS | April 13, 2011

Former Assistant Secretary of Education Diane Ravitch tells reporters to dig deep when states or school districts or even individual schools claim big educational gains; chances are someone is gaming the system. She shows how such gaming works – and when it comes to asking the right questions, Ravitch could be anyone’s assignment editor.

Be skeptical of miracle schools. Sometimes their dramatic gains disappear in a year or two or three. Most such claims rely on cheating or gaming the system or on intensive test prep that involves teaching children how to answer test questions. These same children, having learned to take tests, may actually be very poorly educated, even in the subjects where their scores were rising.

Whenever a school has a dramatic increase in test scores in only one or two years, ask questions about the participation rate: How many kids started the school? How many were tested? Were low-performing students held back in a previous grade to inflate the scores? Reporters should also check to see if there has been any verification to make sure that there was no cheating (e.g., a high erasure rate, changing scores from wrong to right). Who graded the papers? Did teachers have access to the test questions before the test was given? If so, they might have taught the test questions during practice sessions.
