Vocabulary is the single biggest predictor of 11+ success across every subject — yes, even maths and reasoning, where a child who misreads consecutive or remainder loses marks they could easily have won. But rote word lists alone don't work; children forget them within a week. The good news is that a steady, sensible 30 minutes a day, built on reading rather than cramming, grows vocabulary that actually sticks and shows up in the exam.
Why vocabulary decides the paper
Most current 11+ English papers are set by GL Assessment, now the dominant provider across the majority of grammar-school regions. (CEM's older standalone 11+ papers were largely phased out around 2022-2023; if you read older advice comparing "CEM vs GL", treat it with caution.) A typical GL English paper runs about 50 minutes: one fiction or non-fiction passage with roughly 18-30 comprehension questions, plus short vocabulary, spelling, punctuation and grammar sections of around 8-10 questions each. Essex families sit the CSSE exam, and many independent schools use the ISEB Common Pre-Test. In all of them, vocabulary is not a single section — it runs through comprehension, cloze, synonyms, antonyms and word-meaning-in-context. A wide, precise vocabulary is the difference between guessing and knowing.
Results are reported as a Standardised Age Score (SAS), age-adjusted so a younger child is not penalised, with 100 as the average and most scores falling between roughly 69 and 141. Many grammar schools look for around 111 or above, though exact pass marks vary by area and year. Vocabulary is one of the most reliable ways to nudge a raw score upward, because it pays off in every part of the paper at once.
Where vocabulary really grows
From reading. A child reading 15 pages of a novel each day meets around 200 different words — many of them new, and all of them in context, which is exactly how the exam presents them. Lists teach a word in isolation; reading teaches a word doing a job in a sentence. That context is what makes the meaning stick and lets a child recognise the word months later under time pressure.
Non-fiction matters too. Newspapers written for children, biographies, and information books introduce the more formal, abstract vocabulary that comprehension passages love — words like reluctant, abundant, deteriorate and consequently. Mix fiction and non-fiction across the week so your child meets both storytelling language and explaining language.
A 30-minute daily plan
- 20 minutes reading — fiction most days, non-fiction two or three times a week. Let your child choose books they enjoy; a page turned willingly beats a page endured.
- 5 minutes collecting — jot down 3 unfamiliar words from the day's reading, with the sentence they appeared in. The sentence is the memory hook.
- 5 minutes drilling — a short synonyms, antonyms or meaning-in-context exercise. Try a set of our free vocabulary worksheets, then check recall the next day.
This is deliberately light. Thirty focused minutes daily, six days a week, beats a two-hour Sunday marathon that leaves everyone frazzled. Consistency, not intensity, builds a lasting word bank.
Why context beats flashcards
Words have shades of meaning that lists can't capture. Conceal and hide look like synonyms — but you would hide under a duvet, not conceal yourself there. The 11+ tests these shades constantly, most obviously in closest-in-meaning vocabulary questions where every option is roughly right and only one is best. Teaching your child to ask "which word fits the sentence exactly?" rather than "which word means something similar?" is worth more than a hundred memorised definitions.
This is also where homophones trip pupils up. Knowing a word's sound is not the same as knowing which spelling and meaning the sentence needs. A quick daily habit of noticing confusables pays off in both comprehension and the spelling section.
| Confusable | Meaning | Memory trick |
|---|---|---|
| practice / practise | noun / verb | "ice" is a noun; the noun is practice |
| its / it's | belonging to it / it is | it's always shortens "it is" |
| there / their / they're | place / owning / they are | their has an "heir" who owns things |
| stationary / stationery | not moving / paper | e for envelope = stationery |
| affect / effect | to influence / a result | Action = Affect (verb) |
Build words from their parts
English is largely built from Greek and Latin roots, prefixes and suffixes. A child who knows a handful of these can decode words they have never met — a genuine superpower in an exam full of unfamiliar vocabulary. When your child hits a hard word, ask "what parts can you see?" before reaching for a dictionary.
| Word part | Meaning | Example |
|---|---|---|
| aud- | hear | audience, audible |
| spect- | look | spectator, inspect |
| bene- | good | benefit, benevolent |
| -phobia | fear | arachnophobia |
| trans- | across | transport, translate |
Layer synonym and antonym work on top. For each new word, ask for one word that means the same and one that means the opposite — a small drill that mirrors two of the most common GL question types and doubles the vocabulary gained from every entry. Our post on synonyms and antonyms shows the exam approach in detail.
Upgrade words for writing too
Vocabulary is not only for comprehension. If your child faces a creative or continuous writing task — common in CSSE and independent-school entry — a bank of precise, ambitious words lifts their marks. Keep a short "upgrade list" on the fridge: swap said for murmured, insisted or whispered; swap nice for welcoming, generous or serene; swap big for vast, towering or immense. The aim is precision, not showing off — the right word beats the biggest word every time.
Common mistakes to avoid
- Cramming lists the week before. Words learned in a panic rarely survive to exam day. Start early and go slowly.
- Learning definitions without sentences. A word with no context is half-learned; always keep the sentence it came from.
- Ignoring "closest in meaning". In vocabulary questions, several options are near-synonyms — train your child to pick the exact fit, not the first plausible one.
- Never revisiting. A word met once is soon forgotten. Recap yesterday's three words at the start of each session.
Turn these habits into timed practice with our free mock papers and the revision hub, so vocabulary is tested the way the real exam tests it — under the clock. For a full picture of the paper and how scoring works, the exam guides are a useful next stop.
Frequently asked questions
How many words a day should my child learn?
Three well is better than twenty badly. Three new words a day, properly revisited, is around 1,000 words a year — a huge, durable gain that far outperforms long lists forgotten within the week.
Are word lists a waste of time?
Not entirely — a curated list is useful for revision and for spotting gaps. But it should support reading, not replace it. Learn words in context first, then use lists to check and consolidate what your child already half-knows.
What SAS score do we need?
Many grammar schools look for a Standardised Age Score of around 111 or higher, but exact requirements vary by region and year. The score is age-adjusted with 100 as the average, so treat any single practice result as a guide, not a verdict.
