What’s the Senior Party? When? Why?

The Senior Party is a fun & important Interlake tradition. It’s an all-night party that happens immediately after our students’ graduation ceremony in June. The Senior Party gives our kids a special celebration event full of wonderful memories – plus a safe place to party with friends and class-mates. Why risk celebration options that won't ensure your student's safety?


Where’s the Party?

Party locations change every year and are a BIG SECRET. Students won’t know where they’re going until the bus arrives at their destination. Rest assured that each location is a secure, drug- and alcohol-free environment with lots of food, music, entertainment, games, and much more … all night long!


How much are Tickets?

The regular ticket price of $175 is available from Feb.1.

Purchase your student’s ticket now to reserve a spot. Registration will be complete as soon as all forms are received.


How Do I Purchase a Ticket?

There are three ways to get your ticket.

  1. Pay by check. Make checks payable to “Interlake PTSA,” with “Senior Party” in the memo line.
    • Please fill out and include the Senior Party Information form below so we know your student’s name and contact information.
    • Drop off in the main office or mail to: Interlake PTSA, 16245 NE 243th Street, Bellevue, WA 98008
  2. Purchase online. A $5 PayPal fee will be added to cover the cost of online payments.


       3. Request a scholarship. Students who are eligible for scholarships should see their counselor right away!

Because this party requires a lot of volunteer time and energy as well as significant financial commitments, tickets are non-refundable. However, tickets may be transferred or donated to another Interlake Senior prior to the May 31st registration deadline. 


How Can I Help?

The success of this event each year reflects the generous spirit of our school community. Please consider joining our parent planning team, supporting our fundraisers, and/or sponsoring a student in need. You can donate directly to Interlake PTSA Class of 2018, or provide a full or partial student ticket scholarship here:
