 - Important SENIOR PARTY Update -

 If your Senior procrastinated a little and didn’t secure a senior party ticket in time, there’s still hope!

 Tickets are currently sold out, but we’re starting a pre-paid waitlist to secure a 5th charter bus.  Here’s how it works:

 The Class of 2018 Parent Team is now accepting pre-payment for the Priority Wait List.

  *   Pre-payment allows your student to request a preferred charter bus with friends during lunch signups on Tues 5/8 & Fri 5/11, or by email after those dates at<>. First come, first served!
  *   The order in which pre-payment is received by the Class of 2018 Parent Team determines the order in which students will be moved from the Wait List to the Confirmed List.
  *   With enough pre-payments, we’ll be able to add a 5th bus with plenty of capacity for additional seniors.
  *   If any pre-paid seniors are not moved from the Wait List by May 31, full reimbursement will be processed ASAP.

There are three ways to be on the Pre-Paid Priority Wait List:

1. Online via PayPal (includes a $5 PayPal fee).

We recommend paying online and forwarding your email receipt to if you’d like to get as close to the top of the Wait List as possible.

2. In Person to avoid the $5 PayPal fee. Just fill out the Senior Party Forms available at the bottom of this webpage. Make your check payable to Interlake PTSA Class of 2018, and drop off your check and form in the PTSA lockbox in the main school office.

Please note that there may be a processing delay between dropping a check in the lockbox and receipt by the Class of 2018 Parent Team.
3. Scholarships are available to qualifying students. Students should talk to their counselors.
Participation in this year’s Senior Graduation Party is exceeding all expectations based on prior years … Yay for Class of 2018! The Senior Class Parent Team is working hard to ensure that all seniors who want to attend this fun, safe, chaperoned event are able to enjoy a great night with their classmates. So please don’t delay in securing a spot on the Pre-Paid Wait List!

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:
