7h•Onsite

About The Position

This position is for the 2026-27 School Year. The Math RTI Specialist is a certificated, classroom-adjacent role focused on accelerating student learning in mathematics across the secondary grades, with a primary emphasis on middle school. The specialist designs and delivers Tier 2/Tier 3 interventions (push-in, pull-out, and small-group), uses data to identify student needs, monitors progress, and collaborates closely with classroom teachers, counselors, Special Services, Title I/LAP, and the Culture Department. As assigned based on student and program needs, this position may include teaching classroom-based mathematics (e.g., Algebra 1 at the middle level). This is not a supervisory position and does not include the evaluation of colleagues. Chief Leschi Schools, formerly known as the Puyallup Tribal School, was founded in 1976 to address the high dropout rate of the youth of the Puyallup tribe. It is the largest of seven tribal schools in the state of Washington and one of approximately 200+ tribal schools in the United States. It is also one of the largest tribal schools to be funded by the Bureau of Indian Education.
