Lastly, an often-overlooked aspect of choosing between the SAT and the ACT is composite improvement. Since the ACT composite score is generated by averaging the scores from the four sections (English, Math, Reading, and Science), a student must improve in almost every aspect of the exam in order to improve their overall score—gains in only one section will not make a big difference in raising the composite score, since those gains will be spread out when the scores are averaged together. One lagging section can keep a composite from breaking into the 30’s. On the SAT, however, answering five more questions correctly between the Critical Reading and the Math sections could raise your score from a 1250 to a 1300. As you can see, on the SAT, smaller improvements can make a huge difference in your composite score.
A test developer's choice of which style or format to use when developing a written test is usually arbitrary given that there is no single invariant standard for testing. Be that as it may, certain test styles and format have become more widely used than others. Below is a list of those formats of test items that are widely used by educators and test developers to construct paper or computer-based tests. As a result, these tests may consist of only one type of test item format (., multiple choice test, essay test) or may have a combination of different test item formats (., a test that has multiple choice and essay items).
