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.
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.
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.
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.
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.
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 — dyslexia, ADHD, anxiety, giftedness — a private conversation with the SENCO is more valuable than the general tour. Ask this directly when you book: "Is there an opportunity to speak with your SENCO during the open day?"
Questions to ask at every open day
The question most parents are afraid to ask
"How many children left mid-prep in the last two years, and why?"
This question makes most parents uncomfortable. It shouldn'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?
If you feel uncertain after a visit
Uncertainty after an open day is usually meaningful. Try to identify: is the uncertainty about the school (something felt off) or about fit (this is a fine school, but not right for our child)? These require different responses. The first warrants further investigation. The second warrants ruling the school out.
