Founded in 1919 by Frank G. Moran, Lakeside enrolls 891 students overall, 296 of them in the Middle School. The academic program is built on critical inquiry and writing, project-based learning, and experiential education, and it is designed to produce students who can work through unstructured problems rather than simply perform well on tests.

What Makes Lakeside Admissions Unique?

Two things set Lakeside apart at the Middle School level. First, there is no traditional interview. Applicants attend a small-group admissions activity instead, where faculty watch how a child collaborates, listens, and works through an unfamiliar problem alongside peers. There is no parent interview component at all. Second, Lakeside will not look at anything beyond the required materials. Supplementary portfolios, extra recommendation letters, and private meetings with the admissions office are all declined, in the interest of keeping the process equitable. What your child submits is what gets read, which puts unusual weight on doing the required pieces well.

Top Tips for Applying

  • Register for the SSAT or ISEE by December 2026 so scores arrive before the January 28 deadline.
  • Choose one test and sit it once. Lakeside accepts only one set of scores per applicant.
  • Treat the admissions activity as a collaboration exercise, not a performance to rehearse.
  • Ask teachers for evaluations in the fall, well before winter break workloads build.
  • Submit the January 14 items early; the two deadlines are two weeks apart and easy to conflate.
  • Do not send extra materials. They will not be reviewed and can signal you did not read the instructions.

Best Practices for Families

  • Attend the October 25 open house and book a separate small-group tour, since they cover different ground.
  • Have your child, not a parent, write the student essay and activities form.
  • Keep the parent statement candid, including genuine areas for growth.
  • Build a realistic list alongside Lakeside rather than treating it as a single target.
  • Start conversations about fit early enough that your child can speak about the school in their own words.

What the Lakeside Middle School Application Requires

To apply to Lakeside Middle School, you will need to submit the following:

  1. 01Admissions Testing: SSAT or ISEE

    For 2027–2028 entry into grades 6 through 8, Lakeside accepts either the SSAT or the ISEE. Scores must come from a test taken between September 1, 2026 and January 28, 2027, and the school will accept only one set of scores per applicant. The SSAT code is 4462 and the ISEE code is 481120. Lakeside publishes no minimum score and admits students across a wide range. Because families now have a real choice between the two exams, it is worth reading our comparison of the SSAT and the ISEE before registering. Our private school test preparation runs tracks for whichever exam suits your child.

  2. 02Student Essays and the Interests and Activities Form

    Both are PSIS common forms completed inside Aryval and due January 14, 2027. Students choose from several essay prompts and must stay within the stated word limit. The interests and activities form covers extracurriculars, jobs, and responsibilities outside the classroom. Lakeside asks explicitly that students complete these without help from parents, guardians, or teachers, and because PSIS forms are shared with every PSIS school you apply to through Aryval, the writing needs to stand on its own rather than being tailored to one school.

  3. 03Parent and Guardian Statement

    Also due January 14, this form asks parents to describe the applicant’s strengths and opportunities for growth, within a set word limit. The instinct to present a flawless child works against you here. Admissions readers are looking for self-aware families who can name what their child is still working on. Our parent statement guidance walks through how to strike that balance.

  4. 04Teacher Evaluations and Personal Reference

    Lakeside requires exactly two teacher evaluations, due January 28. One must come from a humanities teacher in English, history, or social studies, and one from a math or science teacher, with at least one from a current teacher. If the same teacher covers humanities, math, and science, submit a current-year math evaluation and a prior-year humanities evaluation. A separate personal reference form must be completed by a teacher, administrator, or coach who has observed your child in a group setting within the past two years. Additional letters beyond these will not be accepted.

  5. 05Transcripts and School Administrator Form

    Records must come directly from your child’s school through a request submitted in Aryval, and are due January 28. Lakeside asks for the first complete report card from 2026–2027 plus the full-year transcript from 2025–2026. The PSIS school administrator form, which reports attendance, is completed by a registrar, principal, or division head. If your school releases report cards after the deadline, Lakeside will not penalize the application for that delay.

  6. 06The Middle School Admissions Activity

    Every Middle School applicant must register for and attend an admissions activity after submitting the preliminary application. It is a hands-on small-group session that replaces the interview entirely. Students visit a Lakeside classroom, meet faculty, and work with peers while admissions staff observe how they collaborate. Nothing needs to be prepared in advance. While students take part, parents and guardians attend a concurrent information session and question-and-answer with the admissions team.

How Cardinal Education Helps

We have spent twenty years helping families navigate private school admissions, and our work starts well before an application does. For Lakeside in particular, the leverage sits in places families tend to underestimate: choosing the right entrance exam, helping a child write in their own voice, and building the collaborative habits that a group admissions activity actually reveals. Our Seattle team knows this market and the schools that sit alongside Lakeside on most families’ lists. Families of Asian American applicants may also want our companion page on Lakeside admissions written specifically for that community.

“The admissions consultant who worked with my child was very efficient. He helped us with every detail of our application to Lakeside.”— Lakeside Parent, Cardinal Education Client
