No scores from before September 2026 will be accepted. Additionally, we will only accept and consider one set of admission test scores per applicant.

SSAT scores must be received on or before January 28, 2027 to be considered on time for middle school applicants.
To find out which test level your student should take, please visit SSAT.
Lakeside's SSAT School Code: 4462
Middle School Admissions Activity
To be completed by January 28, 2027
All Middle School applicants are required to register for and attend an admissions activity after submitting the preliminary application form. This fun, hands-on session is held in small groups and designed to help us get to know your student while observing how they collaborate with peers in a group setting.
The admissions activity also gives students a chance to visit a Lakeside classroom, meet faculty, and learn more about daily life at school. Common topics students ask about include lunch, clubs, athletics, and the schedule. There’s no need to prepare anything in advance.
While students are participating in the activity, parents and guardians are invited to attend a concurrent information session and Q&A with a member of the admissions team. Please note: this activity fulfills the interview requirement for Middle School applicants, and there is no one-on-one or parent/guardian interview component.
Registration for the first admissions activity session opens in Aryval in late September and will continue on a rolling basis. Sessions take place after school, in person at the Middle School campus, from early October through the end of January.
Families whose primary residence is outside of Island, King, Kitsap, Pierce, or Snohomish Counties may register for a virtual activity via Zoom. Virtual session dates will be listed in Aryval beginning September 1.
Please note: The admissions activity does not include a campus tour. Small group tours are offered separately from October through January, with registration also available in Aryval starting in late September. Another wonderful way to explore Lakeside is by attending our All-School Open House on October 25 where you can meet faculty, visit classrooms, and learn more about our programs. More information is available on the Events page of our website.
