Equity Statement

Lake Oswego School District continues to make progress toward a 100% graduate rate, a stated goal for the state of Oregon by 2025. MTSS maintains high expectations for all students and increases support as needed, based on individual student data in the areas of academics, social-emotional, and behavior. MTSS aligns with and supports the LOSD priorities and values outlined in the Strategic Plan, including achieving equitable academic outcomes, creating a culture of belonging, and promoting health and resiliency. MTSS supports our District mission:

We are a learning community dedicated to creating a culture of belonging and educational excellence.

Overview of the Tiers

MTSS is based on the premise that classroom instruction should meet the needs of eighty percent of students. Fifteen percent of students will need targeted supplemental instruction. The remaining five percent of students will need intensive and individualized support. These increased layers of instruction are divided into tiers. Each will utilize data to identify which students need additional instruction or intervention. Progress monitoring will determine its effectiveness resulting in individual student growth with the targeted skill.

Immersion Programs
Interventions and support for students in Immersion programs begin with multiple intervention cycles in the language of instruction. English interventions are used if a student is not responding to intervention.

Supporting Positive Student Behavior

MTSS Icon

Behavioral expectations grounded in school and community values and clearly defined across settings provide transparency for all staff, support students’ skill development, and promote a positive and predictable learning environment for all.

Schools have clear definitions for behaviors that interfere with academic and social success and a clear policy/procedure for addressing behaviors.
