Open days are your best research tool and your best gut-check. No prospectus will tell you whether the headteacher looks your child in the eye when they shake hands. No league table will tell you whether the corridors feel calm or frantic at 8:45am on a Tuesday.
The questions that matter aren't on the prospectus. Ask how the school handles a child who's struggling, what the average class size is in the year your child would join, who the head of pastoral care is, and how parents are told when something goes wrong. Watch how staff answer.
Open day seasons across the academic year
Open day seasons across the academic year. The peak season (September–November) is when most schools hold their main event. Book as soon as dates are announced.
Yes, it's a lot of travel and a lot of weekends. But you can't shortlist schools you haven't visited. One visit eliminates — or confirms — faster than hours of online research.
When open days happen
Prep schools run open days in two predictable windows each year.
Autumn season: September through November. This is the main open day window. Most schools hold their principal open day here, timed to coincide with the start of the new school year when staff energy is high and the school is at its most presentable. Attendance is heaviest in this window. Book early.
One practical note: almost all open days take place during term time on weekday mornings. You'll need to let your child's current school know in advance. Most schools are understanding — just give them reasonable notice and keep the absence brief.
Spring season: February through March. Quieter, often better for follow-up visits. Useful for schools you're seriously considering after autumn shortlisting, or for families just beginning their research in the new year.
Summer events: June and July. Some schools hold summer tours or informal visits that fall outside the main open day calendar. These are typically less structured but worth attending if you missed the main events.
If you're reading this already past the main registration round, the piece on boarding school late applications covers how to approach schools directly when the official process has moved on — private visits are often easier to arrange for late applicants than the open day calendar suggests.
Open days vs private visits
Open days are for prospective parents who haven't yet registered. Private visits — which include a tour with current pupils, sometimes a meeting with the head, and occasionally an informal assessment — are for families who have already registered. These are separate events. Attending an open day doesn't give you a private visit automatically. You must register first — see our admissions timeline guide for a full picture of when registration windows open for each entry point.
Should you bring your child?
It depends on the age and the school — but as a general rule, yes.
For pre-prep and early prep visits (ages 3–8), bringing your child is usually encouraged. Schools at this stage are actively assessing whether the child seems engaged and settled in the environment, and open mornings often include informal play or activity sessions designed for this.
For later prep visits (Years 5–8), bringing your child matters for a different reason — their reaction. A child who walks into a school and immediately relaxes, asks questions, or starts chatting to the pupils showing them around is telling you something important. So is one who goes quiet and wants to leave.
You don't need to bring them to every visit. If you're doing early-stage research across five or six schools, visit the ones that feel unlikely without them first. Save your child's first impressions for the schools that genuinely excite you.
Before you go: the preparation most parents skip
A school visit without preparation is a tour with strangers. Arriving with specific questions changes the dynamic entirely.
Before each visit, do three things.
Read the most recent ISI or Ofsted inspection report. Independent Schools Inspectorate reports are publicly available. Look at the summary judgements, but also read the "area for development" section — this tells you what the school was told to improve. A report that's two or three years old is worth checking: has the school acted on those recommendations?
Look at the Year 8 or Year 11 destination data. Most prep schools publish where their leavers go. If 80% go to one senior school, the prep is effectively a feeder. That might suit you — or it might not. Either way, you should know — see our guide to choosing a prep school for a full framework on using destination data in your shortlisting decision.
Write down three specific things you're worried about. Not generic things like "quality of teaching" — specific things, like "my son has dyslexia: what is the support structure?" or "we may need to move in Year 5: how does the school handle mid-year joiners?" These become your interview agenda.
What to look for during the visit
The first five minutes
How you're greeted matters. An open day that feels chaotic, where no-one seems to know you're coming, tells you something. A head or deputy who personally greets families at the door tells you something different.
The pupils
The most reliable signal in any school visit is the children, not the staff. When pupils walk past during a tour — do they make eye contact and say hello, or do they look away? Do they seem proud of their school, or indifferent to it?
You can't fake this. A culture of confident, curious children is built over years.
The SENCO and pastoral provision
For families with a child who has any additional needs — whether that's dyslexia, ADHD, anxiety, autism, sensory processing differences, or giftedness — a private conversation with the SENCO (Special Educational Needs Coordinator) is more valuable than the general tour. Don't wait to be introduced. Ask directly when you book: "Is there an opportunity to speak with your SENCO during the open day?"
Come prepared with specifics. Not "do you support children with dyslexia" — every school will say yes. Instead: "How many children currently have an EHCP or learning support plan? What does in-class support look like on a typical Tuesday morning? Do children leave lessons for one-to-one support, or is it done within the classroom?" The answers will tell you far more than the brochure.
Also ask about the pastoral structure — tutor groups, house systems, how the school spots a child who is struggling socially but not academically. The best prep schools have eyes on every child, not just the ones whose difficulties are obvious.
The same applies if your child is academically strong or particularly gifted in one area. It is worth asking how the school stretches children who find the standard curriculum unchallenging — whether that is through extension work, subject acceleration, enrichment programmes, or simply a culture that encourages depth over speed. A school that has thought carefully about its most able pupils usually has thought carefully about all of its pupils.
Questions worth asking on the day
- What are the most common senior schools your Year 8 leavers go to?
- How do you identify and support children who are finding things difficult academically or pastorally?
- What is your average class size in Years 3–6, and does it change in Years 7–8?
- How much homework do children typically have in Year 5 and Year 8?
- What is your policy on tutoring outside school?
- How do you communicate with parents when something is wrong — not the formal parents' evening, but informally?
- What happens if my child is registered here but we need to move house mid-year?
- How many children left the school mid-prep in the last two years, and why?
If the school has boarding provision — whether full boarding, weekly boarding, or flexi — it's worth asking about that side of life separately. These questions apply whether you're a UK family considering boarding or an international family for whom it's the whole plan.
If you're considering boarding
- Can we see a boarding house — not just the classrooms? What do the dormitories look like, how many children per room, and what is the evening routine?
- What does a typical boarding weekend look like? Are children busy with structured activities or is there significant free time?
- How is homesickness handled — particularly in the first few weeks of the first term?
- How does house staff communicate with parents? Is there a regular update, a parent portal, or do you only hear when something goes wrong?
- What are the exeat and half-term arrangements? How many weekends per term do boarders go home, and what happens to children whose parents cannot collect them?
The question most parents are afraid to ask
Most parents skip this one because it feels confrontational. It isn't. A healthy school with low turnover will answer it confidently and openly. A school with a retention problem will either deflect or give an answer that feels incomplete.
Families leave prep schools for many reasons — relocation being the most common. But a pattern of families leaving for pastoral or academic reasons is worth knowing about.
After the visit
Within 24 hours, write down your impressions while they're fresh. You'll visit multiple schools across multiple terms. They blur together. A simple note — three things that stood out, one concern — is enough.
A useful prompt: imagine dropping your child off on their first day. How does that feel? Not "did the school perform well on the tour" — how did it actually feel in your gut?
Ask your child first.
Before you share your own impressions, ask your child what they thought. Their answer will often surprise you. Children notice different things to parents — the food, whether another child spoke to them during the tour, whether they felt comfortable or on edge. Their gut feeling matters, especially for children old enough to articulate it.
Try asking: "If you had to go to school there tomorrow, how would you feel?" It cuts through politeness faster than most questions.
Keep a visit log.
If you're visiting three or more schools, they'll blur together within a week. Write notes immediately after each visit — not a full report, just: three things that stood out, one thing you want to follow up on, and your child's reaction in one sentence. A running document, a note on your phone, or even a voice memo recorded in the car on the way home all work equally well.
By the time you reach decision point, these notes will be more useful than any brochure.
If you're visiting from overseas
Coming from abroad to visit UK prep schools takes real planning — and it's absolutely worth doing. No amount of virtual tours or video calls replaces the feeling of standing in a school and watching how the children move through it.
A few things that make the trip work better:
Group your visits tightly. If you have a shortlist of four or five schools, try to arrange visits within the same two or three days rather than spreading them across separate trips. Call each school's admissions office directly and explain that you're travelling from abroad — most are very accommodating when it comes to arranging dates that cluster. Some will offer a private visit at short notice for overseas families specifically because they understand the logistics.
Prioritise private visits over open days. Open mornings are excellent, but if you can only make one trip, request a private visit rather than attending a general open day. Private visits are more candid, less crowded, and allow you to ask questions that might feel awkward in a group setting. Call the admissions office, explain your situation, and ask directly — the answer is often yes.
Allow time after each visit. Back-to-back school visits with no time to reflect in between means everything blurs. Even 30 minutes between visits to make notes and talk it through as a family makes a significant difference.
London as a base works well for day schools. Most of the top London prep and senior day schools are reachable within an hour from central London. For boarding schools in the home counties, the south-west, or the Midlands, consider basing yourself somewhere central like Oxford or Bath if you're visiting multiple schools in that region.
What to ask about boarding
Whether you live twenty minutes away or on the other side of the world, sending a child to board raises the same core questions: who is looking after them day to day, what does their life actually look like, and how will you know if something is wrong?
These are the questions most parents want to ask but feel awkward raising in a group setting. Ask them anyway — a good boarding school will welcome every single one.
Communication and pastoral contact: How often will you hear from the school? Is there a regular written or video update from the houseparent, or do you only hear when something is wrong? Does the school use a parent portal or communication app? Can your child call or video-call you freely, or are there set times?
Travel and logistics: Does the school help with airport transfers at the start and end of term? Many boarding schools have well-established relationships with transport providers for international pupils — ask whether this is organised centrally or left to individual families. For a full breakdown of boarding costs including extras and travel, see our complete prep school fee guide.
Exeat weekends: When the rest of the school goes home for a weekend exeat, what happens to children who can't travel home? Most schools with significant international boarding populations have guardian arrangements or organised activities for these weekends. Ask specifically: "What did international boarders do last exeat weekend?"
Day-to-day life: Ask about food — not whether it's good, but whether it's varied and whether dietary requirements (religious, cultural, medical) are genuinely accommodated. Ask about activities — what does a Tuesday evening look like? A Saturday afternoon? A child who is engaged and busy is a child who is settled.
Homesickness: Every child experiences some version of it. Ask the school how they spot it early, what the houseparent does in the first few weeks of term, and whether there's a structured settling-in programme. The best boarding schools talk about this openly because they've thought about it carefully. Schools that brush past it with "children settle quickly" are telling you less than schools that describe a specific process.
These questions don't signal anxiety — they signal that you're a thoughtful parent who has done their research. Any good boarding school will welcome them.
If you feel uncertain after a visit
Feeling unsure after a visit is completely normal — and it is usually telling you something useful.
The question worth asking yourself is: does the uncertainty feel like something was off about the school, or does it feel more like this just isn't the right place for your child?
Those are different things. If something felt off, go back for another look before ruling it out. If it simply didn't feel right for your family, trust that feeling and move on. Sit with it for a day. You'll usually know.
The visits give you the feeling. preptimely handles the dates — so the deadline side of things is one less thing on your plate. You've just read the map. We help you follow it.
