The verdict

You likely already know Eastside Preparatory School (EPS) as one of the Eastside's default independents for tech families: the no-Advanced Placement (AP), no-International Baccalaureate (IB) school in Kirkland that elite colleges keep admitting from anyway. The shorthand holds up. What it hides is how narrow the door is, and what the model asks of you once inside.

The entry math comes first: 36 fifth-grade seats, roughly 18 more in sixth, and 30–35 more in ninth. Every other grade opens only when a family leaves, which almost never happens on the enrollment evidence. Second is the bet itself. You trade the portable, externally graded rigor of AP and IB for a proprietary seminar curriculum whose value depends on the college-counseling office translating it, a translation that has demonstrably worked so far. Third is money: $46,600 tuition for 2025–26 is the floor, not the total, at a school that tells full-pay families their tuition covers only about 92% of what their child costs. It's a strong fit for a self-directed, discussion-happy kid whose family accepts all three. It's a harder look if your student needs the scaffolding of branded coursework, or you'd be entering at a grade where seats barely exist.
