The SAT is given seven times per year. While the dates change slightly from year to year, they are always on: the first Saturdays in October, November, December, May, and June; The second Saturday in March; and the third or fourth Saturday in August.
When is the best time to take the SAT? Of course, the short answer is that you should take the SAT when you are ready. Preparation for the SAT takes anywhere between one and three months. There’s also some evidence to suggest that there are significant differences in the scaling of SAT exams given in different months. For example, it appears that the June exam consistently has the most advantageous scale, whereas the October and November SATs have the least forgiving scales. In other words, the same number of wrong answers gives you a higher score in June than in October or November.
Since you are allowed to select which scores are sent to colleges, regardless of a college’s admission policy, it makes sense to prepare for, and take, several SATs in order to obtain your highest possible score. Also, with the policy known as super scoring, in which colleges only consider your highest score on each component of the SAT, it makes sense to take the test early and often. Not doing so can put you at a competitive disadvantage against students who do take advantage of these policies.
