Well-designed teacher assessments provide crucial information about each student's achievement in the classroom. However, teachers vary in the types of assessment they use so teacher assessments do not usually provide information on how students' achievement compares to externally established criteria. Consider two eighth grade students, Brian and Joshua, who received As in their middle school math classes. However, on the standardized norm referenced math test Brian scored in the fiftieth percentile whereas Joshua scored in the ninetieth percentile. This information is important to Brian and Joshua, their parents, and the school personnel. Likewise, two third grade students could both receive Cs on their report card in reading but one may pass 25 per cent and the other 65 per cent of the items on the Criterion Referenced State Test.

There are many reasons that students' performance on teacher assessments and standardized assessments may differ. Students may perform lower on the standardized assessment because their teachers have easy grading criteria, or there is poor alignment between the content they were taught and that on the standardized test, or they are unfamiliar with the type of items on the standardized tests, or they have test anxiety, or they were sick on the day of the test. Students may perform higher on the standardized test than on classroom assessments because their teachers have hard grading criteria, or the student does not work consistently in class (e.g. does not turn in homework) but will focus on a standardized test, or the student is adept at the multiple choice items on the standardized tests but not at the variety of constructed response and performance items the teacher uses. We should always be very cautious about drawing inferences from one kind of assessment.

In some states, standardized achievement tests are required for home-schooled students in order to provide parents and state officials information about the students' achievement in a wider context. For example, in New York home-schooled students must take an approved standardized test every other year in grades four through eight and every year in grades nine through twelve. These tests must be administered in a standardized manner and the results filed with the Superintendent of the local school district. If a student does not take the tests or scores below the thirty-third percentile the home schooling program may be placed on probation (New York State Education Department, 2005).
