Join the International School PTSA

Support every International School student. Strengthen our community. Make your voice count.

The International School Parent Teacher Student Association (ISPTSA) is a parent volunteer-run 501(c)(3) nonprofit supporting the students, families, teachers, and staff of International School.

We need you to join the ISPTSA and help support programs and activities that benefit our entire school community. Every membership also strengthens our collective voice and gives members a say in important PTSA decisions, including budgets, programs, and major expenditures.

Joining the PTSA is not a volunteer commitment. Simply becoming a member shows your support for our school and our students. Volunteering is always welcome, but never required.

Why Add More Than One Member?

Every membership counts. More members mean a stronger ISPTSA voice when advocating for our students and school community.

Dual, Trio, and Quad memberships make it easy—and more affordable—to include multiple members of your family.

Member Benefits

Your ISPTSA membership dues are tax deductible, and members also receive access to Washington State PTA member discounts on entertainment, travel, shopping, attractions, and more.

Membership Scholarships

We want everyone who wishes to join the ISPTSA to be able to participate.

Our community supports a membership scholarship fund that can cover the membership fee for anyone who requests assistance. There are no financial eligibility requirements, and all scholarship requests are kept strictly confidential. Please contact president1@isptsa.org if you would like to apply for a scholarship.

Want to Do More?

Membership is one important way to support International School. You may also choose to make an additional donation to help fund the programs and activities ISPTSA provides for our students and school community.

Donations are completely optional and can be made at any time.

Thank you for joining the ISPTSA and helping us support every International School student!
