Trimester Schedule Change

Most Highline high schools will switch from a semester system with a six-period day to a trimester system with five longer periods per day, starting in fall 2020. This change will help our students graduate prepared for the future they choose, be that college, technical training or going directly into the workforce.
 
The trimester schedule gives students the opportunity to take more courses and earn more credits in four years of high school. Advantages of this include:
  1. Students have more opportunities to explore their interests outside of required courses in preparation for college and/or career, including the arts, career/technical education and physical education (PE).
  2. Students will have more credit-earning opportunities to meet the state’s new, more demanding graduation requirements.

Starting with the class of 2021, Washington State students are required to earn a minimum of 24 credits to graduate. The new Career- and College-Ready Graduation Requirements are known as Core 24. (If you plan to graduate before 2021, check out your graduation requirements.) 

A committee of staff, parents and district leaders completed a two-year process of researching school schedule options and gathering feedback from staff, students and families. After careful consideration, the trimester system was selected as the best option.

This change affects students attending Evergreen, Highline, Mount Rainier, Raisbeck Aviation and Tyee high schools and CHOICE Academy.
