CDE-Certified Nonpublic Agency

Pillar 5 is a California Department of Education–certified Nonpublic Agency (NPA Identification Code: 9904221), authorized under California Education Code sections 56365–56366.12 to provide special education related services to students with exceptional needs placed by local educational agencies (LEAs).
​
Who we serve: Students in grades K–12, ages 5–21, whose Individualized Education Programs (IEPs) call for behavior intervention services. We serve students in Humboldt County and operate within the Humboldt–Del Norte SELPA.
​
Services we're certified to provide:
Behavior Intervention – Design (BID): Board Certified Behavior Analysts conduct functional behavior assessments, develop behavior intervention plans, and consult with IEP teams.

Behavior Intervention – Implementation (BII): Trained behavior technicians deliver direct 1:1 support, skill acquisition, and behavioral intervention under BCBA supervision — at school, at our certified Arcata center, or in the community.
​
How placement works: School districts and SELPAs contract with Pillar 5 through a master contract and individual services agreement, as provided under California Education Code Section 56366. Services are delivered per each student's IEP, with data-driven progress reporting to the IEP team.
​
