SBG, Standards-based grading

Your child's report card will be distributed in the next few weeks. A report card communicates a student's learning progress during the grading period. All Highline schools are using standards-based grading (SBG) this year, and student’s scores will reflect this. 

SBG, Standards-based grading

The state sets standards for what students should know and be able to do at each grade level.  Standards-based grading (SBG) measures a student’s learning of specific standards. Traditional grading gives students points for individual assignments or effort, but SBG shows a student's progress toward learning standards. SBG ensures that grades reflect a student’s academic performance and understanding of the material, rather than their behavior or effort. This results in a more accurate representation of a student’s abilities and progress.

We’re Listening: How Our Community is Guiding SEL Development

In shaping the future of Social-Emotional Learning (SEL), we prioritized your voice. From 45 Community Advisory Sessions, clear themes emerged: a need for engagement, belonging, and recognition of each student's uniqueness. Students voiced a need for trust, connection, and tools to navigate challenges. Families, community and staff shared a need for collaboration, cultural responsiveness, and lessons on emotional well-being. These insights will guide our 2023-24 SEL framework, ensuring it's community-focused and student-centered.

Our Vision

Together we create and sustain a culture of achievement where all students excel!
