This suggests that students can do well on the ACT when they have completed a considerable portion of the college-preparatory course work that it covers. For many students, this point is reached in the spring of the junior year. Some people believe that ACT scores from recent administrations are somehow adjusted downward if the test is taken many times. For example, students who have already taken the ACT twice might be concerned that, if they test again, their scores on the third testing will be automatically lowered. There is no penalty or score adjustment for taking the ACT more than once.
Students can take it as many times as they want.
Some people believe that it is possible to get a higher score by testing on one national test date than on another. These beliefs are not true. The ACT is designed, administered, and scored in such a way that there is no advantage to testing on one particular date or another. It is true, however, that different forms of the test are administered on different test dates. Recall that each form of the test consists of a unique set of test questions.
