A year of good preparation can be undersold by one anxious morning. The children who perform closest to their ability on exam day aren't the ones who feel no nerves; they're the ones whose nerves have nowhere to take hold, because the day is familiar, the routines are practised, and the pressure has been kept in proportion. All three of those are buildable.
Nerves are mostly about the unknown
Children fear exams the way adults fear turbulence: it's the not knowing what's normal. The remedy is familiarity, built gradually. By exam day, your child should have sat several full papers in realistic conditions: timed, at a quiet desk, without help, ideally occasionally somewhere other than home. If the real exam is your child's first experience of exam conditions, the conditions themselves become the test.
Familiarity extends to logistics. Visit the school beforehand if you can, even just the outside. Know the journey, the arrival time, what they can bring. On the day, aim to arrive early enough to be calm and late enough not to marinate in the car park.
What to say, and what not to say
The most useful sentence a parent can say before an 11+ exam is some version of: "Whatever happens today, you've worked hard and we're proud of you, and there are several good schools where you'll be happy." Children perform worst when they believe a single morning decides their worth or their family's happiness. Deliberately lowering the stakes isn't lying; it's accurate. There genuinely are multiple good outcomes.
Things to avoid in the final week: last-minute cramming, which signals panic and adds nothing; comparisons with siblings, classmates or your own school history; and detailed post-mortems of practice papers. The final week is for light revision, good sleep, exercise and normality.
In-exam techniques that children can actually use
A few concrete tools I teach pupils, because vague advice to "stay calm" helps nobody. The reset breath: when panic flickers, put the pencil down, take one slow breath, and read the question again from the start. The parking habit: a hard question gets a mark in the margin and is left behind without guilt; unread easy questions at the end of the paper are the real enemy. And the mantra for adaptive or hard papers: it's supposed to feel hard, and it feels hard for everyone.
Practising these during mock papers matters, because a technique used for the first time under real pressure isn't a technique, it's a hope.
The morning itself
Breakfast they'll actually eat, clothes sorted the night before, equipment packed the night before, and a departure time with slack in it. Keep the conversation in the car ordinary. Afterwards, whatever they say about how it went, respond warmly and briefly, and do something nice. Children's post-exam self-reports are famously unreliable in both directions, so don't celebrate or commiserate too hard on the strength of them.
If anxiety runs deeper
Some children carry anxiety that preparation alone doesn't touch: sleepless nights, tears over practice papers, stomach aches on tutoring days. That's a signal to reduce pressure rather than add polish, and it's worth acting on early. Sometimes the kindest, highest-performing decision a family makes is adjusting the school list. Confidence is a preparation topic in its own right, and in my sessions it gets treated as one.
