What is the Proctored Writing Sample, and why does it matter for Seattle applicants?

 Ah, yes, the often-overlooked writing sample—until you realize it’s the secret weapon in your child’s private school application. The Proctored Writing Sample (also known as the Online Essay) is a timed, on-the-spot writing assessment used by many top U.S. private schools. For Seattle families applying to competitive schools, it can carry serious weight.

While test scores and transcripts show what a student knows, the writing sample shows how they think. Can they organize their thoughts clearly? Do they write with voice, structure, and purpose—even under pressure? That’s what admissions officers want to see. The catch? Students often get just one prompt, one shot, and 30 minutes.

At Cardinal Education, we make sure your child is ready for that moment—no rambling, no panic, no fluff. Just focused, persuasive writing that says, “I’m ready.” Because on writing sample day, there’s no rewrite.
