Every year, children from state primary schools earn places at SPGS, Godolphin & Latymer, JAGS, and the most sought-after grammar schools in the country. They don’t do it by accident — but they don’t need a £15,000-a-year prep school to get there either.
What they need is a clear plan, the right preparation at the right time, and — crucially — the right support. This guide is for parents starting from a state primary who want to navigate the selective school process without the jargon, the arms-race anxiety, or the expensive missteps.
The actual gap between prep school and state school
Let’s be honest about what prep schools provide and what they don’t.
A good prep school offers smaller class sizes, experienced teachers who understand the selective school landscape, and — from Year 4 or 5 — targeted preparation for specific entry exams. That last part is the important one.
State schools operate under guidelines that limit how much explicit 11+ preparation they can do. Your child’s Year 5 teacher isn’t going to spend lessons on non-verbal reasoning patterns or GL Assessment timing strategies. That’s not a failure — it’s appropriate. But it means the gap between state and prep isn’t about intelligence or teaching quality. It’s about test-specific preparation, which is a learnable skill.
The good news: that’s exactly what targeted tutoring addresses.
The timeline — when to start what
Age 4–8: Foundations, not flashcards
The single most valuable thing you can do at this stage is make reading a daily habit. Not reading scheme books under duress — genuinely engaging books across genres, with conversations about what’s happening and why. Vocabulary built through reading is the single biggest predictor of performance in 11+ verbal reasoning and comprehension. No app replicates it.
Maths games, puzzles, chess, Lego — anything that builds spatial reasoning and logical thinking — are genuinely useful. Don’t start formal exam prep here. You’ll burn your child out years before the exam.
Year 4 (age 8–9): Understand the landscape
This is the year to do your research, not your drilling. Visit schools. Attend open days. Understand what each school tests and how competitive entry is. Most families start too late because they don’t realise how different the admissions processes are across schools — and how early some deadlines fall.
Year 5 (age 9–10): Structured preparation begins
Year 5 is typically the right point to bring in a tutor and start working through the specific skills required. Core maths and English remain the priority, but verbal and non-verbal reasoning should enter the mix — particularly for GL and CEM-format exams. One session per week is usually enough at this stage; intensity can build in the spring and summer terms.
Year 6 (age 10–11): Exam technique and mock papers
By Year 6, the focus shifts to timing, exam conditions, and building the confidence to perform under pressure. Mock papers become valuable here — but only once the underlying skills are solid. Mock papers without foundations just practise anxiety, not performance.
What selective schools actually test — and why it matters
This is where many families go wrong. “The 11+” is not a single exam. The format varies significantly between schools, and preparing for the wrong format wastes months.
London independent schools
Most top London independent schools set their own papers or use ISEB assessments. SPGS sets bespoke maths, English and comprehension papers that test genuine academic depth. Godolphin & Latymer uses GL Assessment. North London Collegiate runs its own format including puzzles and problem-solving. JAGS, City of London Girls’ School, and Alleyn’s each have their own specific requirements.
Grammar schools
Grammar schools use either GL Assessment or CEM (Centre for Evaluation and Monitoring), and which one depends on the local authority and consortium. GL papers follow a predictable format that responds well to systematic practice; CEM papers are designed to be harder to cram for, testing reasoning rather than trained technique. Knowing which your target school uses should shape the entire approach from Year 5 onwards.
The practical implication: before committing to a tutor or preparation programme, identify the specific schools you’re targeting and their exact exam format. Then build backwards from there. Our school placement service exists to help families navigate exactly this — matching a child’s academic and personal profile to the right schools before any exam prep begins.
Choosing a tutor who actually works for your child
Once you’ve identified what you’re preparing for, the tutor you choose will make or break the process.
Subject knowledge is necessary but not sufficient. A tutor who is excellent with one child can be ineffective with another — because the way they explain, the pace they set, and the rapport they build varies enormously. For 11+ preparation specifically, motivation and confidence are as important as content knowledge. A child who loses belief in themselves partway through Year 5 is far harder to recover than one who started later but stayed engaged.
- Experience with the specific schools and exam formats you’re targeting — not just “11+ experience” generically
- A track record with children from state primaries (this is genuinely different from prepping a child already in an academic environment)
- Willingness to adapt their approach to your child’s learning style
- Honest feedback about where your child actually is — not just reassurance
At Ariston, we match tutors not just on subject and school knowledge but on personality fit and teaching style. Our guide to how to choose a private tutor covers this in more detail. The 99.9% successful introduction rate we hold is almost entirely a result of this matching process.
The scholarship and bursary route from state school
For families considering means-tested bursaries or academic scholarships, the landscape is more accessible than many parents realise.
Most top London independent schools are actively trying to broaden access. A child from a state primary with genuine academic potential is often more attractive to a scholarship panel than a heavily-prepped prep school child who has been trained to pass tests. Authenticity and breadth of interest count.
Academic scholarships typically require performance significantly above the entry standard — usually in the top 5–10% of applicants. The preparation here is slightly different: it emphasises breadth, genuine enthusiasm for ideas, and the ability to discuss thinking. A child who can explain why they find something interesting will outperform a well-drilled but passive candidate at scholarship level.
Means-tested bursaries are entirely separate from academic performance in many schools. Some top London schools offer bursaries covering up to 100% of fees for families on lower incomes. Thresholds vary by school and year — worth contacting bursary offices directly rather than relying on published figures.
Common mistakes — and how to avoid them
Starting too early. Year 3 intensive tutoring almost never translates into better Year 6 results. It does translate into exhausted, resentful children who associate learning with stress. Year 4 for research and foundations, Year 5 for structured prep — this is the right cadence for most children.
Choosing a tutor for convenience rather than compatibility. The nearest tutor, the one recommended at the school gate, the cheapest option — these are the wrong criteria. The right tutor is the one who keeps your child engaged and moving forward consistently over 12–18 months.
Treating mock scores as the outcome. Mock scores are diagnostic tools, not predictions. A child who scores 65% in Year 5 and understands every error is in a stronger position than one scoring 80% without knowing why. Focus on what’s being learned from each paper, not just the number.
Not knowing the target school’s format. If you don’t know whether your target school uses GL, CEM, or sets its own papers, your preparation may be misdirected from the start. This single piece of research is worth doing before anything else.
Frequently asked questions
Can a child really get into SPGS or Godolphin from a state primary?
Yes — both schools admit children from state primaries every year. SPGS in particular has increased its focus on widening access. State school children typically need more structured support on exam technique and non-verbal reasoning, since their primary school won’t have covered these explicitly. Starting preparation in Year 5 with the right tutor is usually sufficient for a capable child.
What’s the difference between GL Assessment and CEM?
GL Assessment papers follow a broadly consistent format across verbal reasoning, non-verbal reasoning, English and maths — they respond well to systematic practice using past papers. CEM papers are designed to be more resistant to coaching, testing speed, pattern recognition and reasoning under time pressure in ways that are harder to specifically train for. CEM-focused prep typically places more emphasis on reasoning skills and less on paper-drilling.
When should we start 11+ tutoring?
For most children, the start of Year 5 is the right time — around 12 months before the exam. Starting earlier risks burning a child out; starting in Year 6 leaves insufficient time to build skills properly. The exception is a child with significant gaps in maths or English, where earlier support on the underlying subjects (not exam prep specifically) is sensible.
Do we need a school placement consultant?
Many families manage the process independently, particularly with time to research and a network of parents who have been through it. Specialist guidance adds most value when shortlisting schools that genuinely fit your child’s profile, understanding each school’s entry format and culture, and avoiding the common mistake of targeting schools that look impressive on paper but aren’t the right fit. For families relocating to the UK or unfamiliar with the London school landscape, guidance usually pays for itself in time saved and mistakes avoided.
