Trimester Schedule

Sage Creek High School students will enroll in a trimester schedule.  Students take five classes per day that meet daily for 70 minutes. Each trimester is twelve weeks long (see Trimester Overview).  

The regular school day begins at 8:30 a.m. and ends at 3:30 p.m., with the exception of Wednesdays, which dismiss at 2:30 p.m.

Following are some of the benefits of the trimester schedule:

  • Students can accelerate.  As you review the course sequence for Spanish in the below sample schedules, you see that a student can take three years of a world language in two academic years.
  • Students can re-take a course and still stay on course to meet high school graduation requirements.
  • Students can have an "Off-Roll" period (i.e., "late-start" or "early release").  This is a great opportunity for athletes who need to depart school before the last period of the day is over for games during their designated season. 
  • Students can explore various electives and/or take additional core classes.
  • Students can graduate high school with 300 credits.  The Carlsbad Unified School District high school requirement is 230 credits.

Trimester FAQ's

How can students benefit from participating in the trimester schedule?

  1. Acceleration: See World Language Example in 9th and 10th Grade Sample Schedules
  2. Explore Various Electives
  3. Remediation
  4. Have “Off Roll”, i.e. , Late Start or Early Release
  5. AP Classes Will Be Yearlong (3 trimesters)
  6. Sport Seasons Align with Trimesters


What are some unique elements of the trimester schedule?

  1. Two trimesters are equivalent to a yearlong course in a semester system.
  2. As seen on 9th Grade Sample Schedule, some courses are “gapped” by a trimester or summer break: English 1, P.E. 1, and Spanish 3. 
  3. Students may have one teacher for the first trimester of a course and a different teacher for the second trimester of the course (see Biology 1 on 10th Grade Sample Schedule).
