We have seen an increase in threats to school safety posted on social media platforms or in text messages. We treat threats on digital media—and all threats—seriously. All threats are reported to Safety & Security and law enforcement and are investigated. Students may not be aware that posting a threat on social media, text, or any digital media is a crime that can carry serious legal consequences.

Board Directors Azeb Hagos and Melissa Petrini

School Board Directors Azeb Hagos and Melissa Petrini will host a community conversation on Tuesday, June 4 for families and students across Highline to talk about and learn more about student learning.

The safety of our students and staff is always our first priority. We want to emphasize that we take every safety concern seriously. Whether it's something a student sees in the hallway, hears from a classmate, or reads in a private post on social media, we encourage students to speak up if they see or hear something that might be concerning.

Graduation

We look forward to celebrating our graduates this year. Ceremonies will be at ShoWare Center and the Highline Performing Arts Center. Please read arrival information for each venue.

Students in the culinary and dental programs at PSSC.

Classrooms at Puget Sound Skills Center (PSSC) mirror real-world workplaces—be it repairing cars in an auto body shop, serving guests at the Class Act Restaurant, or seeing patients in a state-of-the-art dental clinic. With 19 diverse programs, PSSC prepares high school juniors and seniors for their chosen futures through specialized career and technical training.  Students can earn industry certifications and college credits while they’re in high school. Here’s a look at two of PSSC’s popular programs, Dental Assisting and Culinary Arts & Sciences.

Make Every Day Account: Why Attendance Matters

Building good attendance habits early is key to success. Students can suffer academically if they miss 10% of the school year, or about 18 days. That's just one day every two weeks.
