EXAMPLE 5 Achievement tests

When you take a chemistry exam, you hope that it will ask you about the main points of material listed in the course syllabus. If it does, the exam is a valid measure of how much you know about the course material. The College Board, which administers the SAT, also offers Advanced Placement (AP) exams in a variety of disciplines. These AP exams are not very controversial. Experts can judge validity by comparing the test questions with the syllabus of material the questions are supposed to cover.
