Career Fairs

PLSO supports and participates in various college and career fairs throughout the state each year.

Career Technical Education (CTE)

CTE provides learners with the knowledge and skills they need to be prepared for college and careers by giving purpose to learning by emphasizing real-world skills and practical knowledge within a selected career focus. PLSO participates in the Career & Hiring Fair at Salem-Keizer Public School’s Career Technical Education Center each year.

PWA builds enduring partnerships between local businesses and Portland-area high schools. By providing students with real-life work experiences and career-learning opportunities, PWA enriches their academic knowledge, inspires them to graduate and help them make informed choices after high school and college. PLSO participates in the NW Youth Careers Expo each year.
