Students, starting in the fall 2008, attended classes based on the letter of the day. Days could range from a-e, and each student's schedule may be different for each letter. This allowed students never to miss too many classes. For example, in past years, students with lab days on Fridays would have fewer lab days when it would be a three-day weekend because school was not in session on Friday. With the letter days, students schedules rotate and eliminate this issue by having a student have lab on a specific letter day.

The current system that the high school employs is not much different from the letter schedule, but is significantly shortened. This is similar to the college system and helps prepare those for college. The school now relies upon a 4-day schedule with a total of eight periods, two of which are dropped every day. This way, a student's schedule rotates through four different options, having class periods 1, 2, 3, and 4 in the morning block, and having periods 5, 6, 7 and 8 in the afternoon, leaving out a morning and afternoon class each day. Every student, regardless of grade, also attends lunch at the same time, which is commonly known as Lunch and Learn. This time is not only utilized for lunch and social purposes, but for kids to receive extra help during their lunch from teachers who are available or meet with clubs and other activities. Each class is approximately one hour long.
