Westview uses a 4 by 4 block schedule for each school year. Under this system, the school year is divided into four quarters, as opposed to other schools' semester and trimester systems. Each student takes up to four classes per quarter, allowing a student to complete up to sixteen classes each year—four classes more than under a semester schedule with six periods (Rancho Bernardo) and one more than under a trimester schedule with five periods (Mt. Carmel and Del Norte). Classes at Westview last an average of 79 minutes a day.
