There are several ways to add an endorsement to an existing Washington State Teaching Certificate:
By earning National Board Certification in a Washington Endorsement Area.
By completing an approved endorsement program see chart, Pathway 3 (this listing is only available in-state programs).
By completing testing/assessments. There are two options available, see the chart to find endorsements available via Pathway 1 or 2 (please note this has been developed by OSPI and looks at the Pathways from your existing endorsement):
Pathway 1: The first Pathway is for closely compatible areas to your current endorsement. You can add these by completing the PESB approved endorsement test and having 90 days of experience. Submit the application form and fee to your ESD office.
Pathway 2: The second Pathway are for somewhat related fields. To add these as an endorsement you need to complete the corresponding PESB approved endorsement test and a Pedagogy Assessment through an accredited college/university.
