Washington private schools are not required to publish state assessment results, and this school's internal test data is not public. Unlike the public-school pages on this site, no score comparison is possible here — treat curriculum labels and matriculation lists as the available evidence.

Competition evidence

Known results compiled from public competition listings (National Merit press lists, tournament PDFs, The Blue Alliance). A missing result is not evidence of absence.

The real comparison is against your public options.

Tuition here runs five figures a year — the question is what it buys over the public schools your address already gives you. A $29 Research Pass unlocks score trends, peer percentiles, competition evidence, gifted-pathway detail, and PTA capacity on every public school in the region, plus 3 full research dossiers for the schools on your shortlist.
