When numerous standards have been developed it is impossible for tests to assess all of the standards every year, so the tests sample the content, i.e. measure some but not all the standards every year. Content standards cannot be reliably assessed with only one or two items so the decision to assess one content standard often requires not assessing another. This means if there are too many content standards a significant proportion of them are not measured each year. In this situation , teachers try to guess which content standards will be assessed that year and align their teaching on those specific standards. Of course if these guesses are incorrect students will have studied content not on the test and not studied content that is on the test. Some argue that this is a very serious problem with current state testing and Popham (2004) an expert on testing even said: “What a muddleheaded way to run a testing program."
