The short answer: yes. Tell the school your child is shy, and frame it as information, not apology. "She's slow to warm up, and once she's comfortable she has a lot to say" tells an interviewer exactly how to succeed with your child. After twenty years across the admissions table: a heads-up like that never marked a child down. It changed how I ran the room. A slower start, an easier first question, more time on the warm-up, which is precisely what you want.
Will telling the school my child is shy hurt their application?
Name the fear first, because it's what keeps parents silent: the worry that "shy" becomes a label in the file: a mark against. Here's the reality from the other side of the table: there is no shyness column. What temperament information does is operational. It tells the person across the table how to bring your child out, which is their whole job anyway. You're not confessing a weakness. You're handing over the manual.
How should I describe a shy child to a school?
The framing formula is description plus the path in, never diagnosis. Three parts: how your child starts, how they finish, and what helps. "He takes a few minutes to warm up, and then he's fully in: he especially lights up about anything with animals." Look at what that one sentence does: it sets the expectation for a quiet start so it can't be misread, it promises the real kid is coming, and it hands the interviewer a door to try. "Shy" as your own plain word is fine; imported clinical language raises questions it doesn't answer, unless something is real, settled, and relevant to share.
Where and when should I mention it?
Where to say it, and when. The timing is the part parents miss: a heads-up only helps your child's interview if it lands before your child walks in. The parent interview often comes after the student's, sometimes with your child right there, so it is the wrong moment to rely on. Lean instead on a short note to the admission office ahead of the visit, two or three sentences by email once the interview is scheduled. Many schools ask in advance what your child is into, and that note is the natural place to fold in the framing, right beside the interests you are already sharing. The application's "anything we should know" field does the same job, one warm sentence, when the timing fits. The parent interview, if it falls later, is a fine place to reinforce, but it is not where your child's own interview gets its help.
What should I avoid when telling the school?
Two cautions, both about placement. Never say it in front of your child. "he's shy" said over a child's head stops being a description and becomes the script, the same rule that holds at home. And don't over-brief: a paragraph of handling instructions reads as the thing that actually worries an admissions office, the over-managing family, while one warm descriptive sentence reads as a family that knows their kid. The dose is the difference.
What does the school's reaction tell me?
And the deeper reassurance: telling the school is a fit test running in your favor. A school that receives "slow to warm up, and worth the wait" warmly is showing you how it will treat your child for the next several years. A school that receives it badly just answered your real question, cheaply and early. Either way, the truth worked, which is the pattern with honesty across this entire process.
