How Measurement Fails Doctors and Teachers
The thing I am always amazed by people who developed metrics is they never seem to stop and think how the metric will be gamed and then take action to prevent this. It should be part of the development of any new metric to have a &quot;evil&quot; team work out all the ways the metric can be gamed so this can be blocked.<p>For example, it should be impossible to &quot;teach the test&quot; other than by teaching broadly the underlying concepts being tested. A well designed test will touch on so many concepts that only a education that is broad will work.
