Which Los Angeles private schools use a Proctored Writing Sample?

Top-tier private schools either require a Proctored Writing Sample or collect timed writing through interviews or campus visits. Harvard-Westlake, Brentwood, Marlborough, Archer School for Girls, and Windward School are just a few that want to see how your child writes in the moment.

Some schools use platforms like Test Innovators to host the sample. Others go old-school and ask for a writing exercise during a visit or interview day—surprise! Regardless of how it’s delivered, what they’re really testing is writing fluency, clarity, and composure under time limits.

That’s where we come in. We prep students for every format: typed, timed, and even the “you’ll write this in-person while we watch you” scenario. Basically, if a school wants to see how your child writes when the clock is ticking, we’ll make sure they’re ready.
