Which specific US private schools require Luxembourg international students to complete a Proctored Writing Sample?

Right now, the big names requiring this include Castilleja School, Crystal Springs Uplands School, Sacred Heart Schools Atherton, and The Nueva School. These are all incredibly selective institutions that attract families from around the globe. 

These schools aren’t trying to make life harder for international families. They’re actually trying to level the playing field. They want to see the real student, not the student with extensive essay coaching or AI assistance. For Luxembourg families, this means they’re looking for authentic voices and genuine thinking, which is actually great news since your kids have unique perspectives from growing up in such an international environment.

Here’s what’s important to know: each school might have slightly different requirements or formats, so don’t assume they’re all identical. Some might give different time limits, others might have specific technical requirements for international students. The smart move? Research early and contact admissions offices directly to get the most current information. Schools change their requirements, and you want to make sure you’re preparing for the right thing. Plus, starting early means your child has time to get comfortable with the format rather than cramming preparation into the last few months of application season.
