How to apply to Harrodian
Harrodian is selective. This means that your child will need to sit an entrance assessment to be eligible for a place.
You must register your child for Year 7 entry via the school website by the registration deadline in October, paying a registration fee. Your child will also need to be registered separately for the ISEB from June 2026.
In late October and early November, a reference is requested from your child's current school. Harrodian holds its own written assessments in November, and all candidates must also complete the ISEB Common Pre-Test by the start of December. Children whose current school does not administer the ISEB will be invited to sit it at Harrodian.
Children who perform well in the assessments are shortlisted for interview. You'll be notified in early January if your child has been selected, and interviews take place on site with Harrodian staff.
You'll receive your child's result in February. If they are offered a place, you will have until early March to accept.
What will my child be tested on?
Harrodian's 11+ assessment is made up of the ISEB Common Pre-Test, alongside written papers set by the school.
ISEB Common Pre-Test
The ISEB Common Pre-Test is an online, multiple-choice assessment. It covers four subjects:
- Maths (adaptive)
- English (non-adaptive)
- Verbal reasoning (adaptive)
- Non-verbal reasoning (adaptive)
Harrodian's written assessments
Alongside the ISEB, Harrodian sets its own written papers in Mathematics (40 minutes), English (40 minutes), Verbal Reasoning (25 minutes) and Non-Verbal Reasoning (30 minutes).

How are places decided?
Children who perform well in the assessments are invited back to Harrodian for an interview in January. This is an opportunity for them to meet school staff and discuss their interests.
Places are offered in February. These are based on:
- performance in the ISEB Common Pre-Test and Harrodian's own written assessments
- the interview
- a reference from the headteacher at their current school
Financial information
Harrodian is a fee-paying school. Take a look at the school website for a full breakdown of fees per year group.
Financial assistance
When exploring independent schools for your child, bursaries are worth considering. They can ease the pressure of school fees and open doors to opportunities that might otherwise feel out of reach.
Bursaries
Bursaries are means-tested awards (based on a family's financial situation) designed to make independent education more accessible. Depending on your circumstances, a bursary could cover part or all of the school fees and sometimes extras like uniforms, lunches or school trips.
Families provide financial information to qualify, and awards are reassessed each year. For many families, bursaries make an excellent education possible that might otherwise seem out of reach.
Visit Harrodian's website to find out what bursaries are available and how to apply.

How can I help my child prepare for the test?
Applying to senior school can feel like a big milestone, but preparation doesn't have to be overwhelming. Here's how you can help your child prepare for test day.
Stay on track with a clear plan
One of the hardest parts of exam preparation is knowing what to focus on, when, and how to make steady progress without it taking over family life.
A clear, structured plan helps your child feel less overwhelmed and more in control. It ensures they build skills in the right order, cover everything they need, and avoid last-minute cramming.
Atom's exam plan makes this easier. Enter your child's target schools and exam dates, and we'll create a personalised weekly plan tailored to the topics they'll be tested on. It shows them what to work on and when, adapts as they improve, and helps them build progress in a calm, manageable way — little and often.
That means less guesswork for you, less stress for them, and a clearer path all the way to exam day.
Build smart exam technique
As your child's knowledge grows, practice tests can help them feel more comfortable with the real exam format.
Atom's mock tests are exact replicas of real entrance exams. They're also unlimited — your child can take the same test repeatedly and see new questions each time. This helps them practise without repeating the same content.
Atom's mock tests are automatically marked. You'll see your child's standardised age score (SAS), where they're doing well, and what they should focus on next. You'll also learn how they compare to other children applying to the same school.
Encourage regular reading
Strong reading skills play a big role in preparation for entrance exams.
Encourage your child to read every day, even for just 10–15 minutes. The key is variety. Mix fiction and non-fiction, different genres, and a range of authors. This helps them become more confident in understanding tone, purpose, and meaning across different texts.
Over time, regular reading will:
- broaden their vocabulary
- improve comprehension and inference
- build confidence in tackling unseen texts
And just as importantly, it can help them enjoy reading — not just see it as exam preparation.
Looking for inspiration? Atom's reading and writing starter kit has suggestions spanning fiction and non-fiction for Years 3–6.
Celebrate progress, not just scores
When you're supporting your child through exam preparation, what really matters is knowing they're moving in the right direction — not just how they scored on a single test.
Atom's progress tracking gives you a clear, simple picture of how your child is doing in each topic and the direction they're moving in. You can see where they're on track, where they might need more practice, and spot progress as it happens.
That makes it easier to give meaningful encouragement, keep motivation steady, and focus on what matters most: consistent improvement, not just one-off results.
Remove the guesswork from ISEB prep.
