11+ Proofreading Questions: A Reliable Method

In short

• Proofreading questions reward a systematic check, not good instincts — children who read for meaning miss errors their own brain silently corrects.
• The reliable method is to run named passes: one for punctuation, one for homophones and apostrophes, one for agreement and tense.
• Errors that hide best are the ones that leave a real word behind, which is why homophones and wrong verb forms dominate these questions.
• Reading the line slowly, almost word by word, beats reading the passage naturally — natural reading is exactly what lets the error through.
• Budget roughly a minute per mark and move on; an unfound error costs one mark, while overrunning costs several elsewhere.

The short answer

Proofreading and error-spotting questions give a child a short passage or a set of lines and ask them to find mistakes — a missing apostrophe, a wrong homophone, a verb that does not agree with its subject, a comma splice. They appear across GL-style papers and in the English sections of many school-set tests, and they are unusually learnable, because they reward a method rather than talent. That is the key insight for parents: children who are good at these questions are not children with sharper eyes, they are children running a system. Left to read naturally, the human brain silently corrects errors as it goes, which is precisely why a child can read a line four times and still miss a wrong their. This guide sets out a method that defeats that, the error types that hide best, and how to pace it. It builds on the rules covered in our punctuation guide and homophones guide.

Why natural reading fails at this task

Fluent reading works by prediction. A skilled reader does not process every letter; they take in enough of a word and the surrounding sense to know what it must be, and move on. That is what makes reading fast, and it is exactly what makes proofreading hard — the prediction machinery supplies the word the sentence needs, and the child's eye slides over the incorrect word actually printed. The stronger the reader, the more efficient the prediction, which is why able readers are often surprisingly poor at error-spotting before they are taught a technique. The implication is that the fix is not to try harder or concentrate more; it is to read differently. Proofreading requires deliberately switching off the prediction and processing what is on the page, which is an unnatural act that has to be practised. Once a child understands why they miss errors, the method below stops feeling like fussiness and starts feeling necessary.

The method: named passes

Run separate passes, each looking for one category, rather than one pass looking for everything. Looking for everything means looking for nothing in particular, and the brain reverts to reading. A workable three-pass structure: first, punctuation — go along the line checking every mark and every place a mark should be, ignoring meaning entirely. Second, the confusable set — stop at every their, there, they're, its, it's, your, you're, to, too and than, and apply the substitution test to each. Third, agreement and tense — check that each verb matches its subject in number and that the tense does not shift mid-passage. Naming the pass matters, because it gives the eye a specific target. With practice the three passes compress and can be run almost simultaneously, but they should be learned separately. Children who are taught this typically improve on error-spotting questions faster than on almost any other 11+ question type, because the gain comes from procedure rather than knowledge.

The errors that hide best

Errors survive because they leave a real word behind. A misspelling that produces a non-word is easy — it looks wrong immediately. An error that produces a legitimate word in the wrong place is nearly invisible, which is why examiners favour them. Homophones lead the field for this reason. Close behind are wrong verb forms that are real words (he done it, they was going), missing plural or possessive apostrophes where the word still reads normally, and repeated small words — the doubled the at a line break is a classic, because the eye jumps the break. Subject-verb agreement errors hide especially well when a phrase sits between subject and verb: the box of apples were heavy reads acceptably at speed because apples sits next to were. Knowing this list turns proofreading from an open-ended search into a targeted one, which is both faster and more reliable.

How long should we spend on each question?

Roughly a minute per mark is a sound working figure, adjusted to the paper's overall timing. The important discipline is the exit rule: if a child has run their passes and found nothing, they should move on rather than keep staring. An unfound error costs exactly one mark; overrunning by three minutes can cost several marks elsewhere on the paper, and it also raises stress in a way that degrades everything after it. Teach the rule explicitly, because a conscientious child's instinct is to keep looking until they find something, and that instinct is expensive under a clock. It is also worth telling children that some lines in these questions are deliberately correct — expecting an error on every line leads to inventing one, which loses marks a blank would not. Our practice papers guide covers building this kind of timing discipline into mock work.

Are proofreading questions on every 11+ paper?

No, and it is worth checking rather than assuming. They are common in GL-style English papers used across most selective regions, and they appear in the English sections of various school-set tests. The Essex CSSE test takes a different approach — its written, free-response format assesses the same underlying accuracy through the child's own writing rather than through spotting errors in someone else's, which means an Essex family should invest in producing correct prose rather than in spotting technique. Independent-school assessment via the ISEB Common Pre-Test includes English components that reward the same knowledge in a different wrapper. The free exam board finder will tell you which format your target schools use in about thirty seconds, and it is worth doing before deciding how much weight to give this question type.

How do we practise proofreading at home?

Two habits, both cheap. First, have your child proofread their own writing a day after they wrote it rather than immediately — the delay weakens the memory of what they intended to say, which is what otherwise overrides what they actually wrote. Second, plant errors deliberately: take a paragraph from anything they are reading, retype or rewrite it with four errors of known types, and have them run the named passes. Making the errors yourself is more useful than buying a workbook, because you can target the categories their own errors log shows they miss. Keep sessions to ten minutes; this is a concentration-heavy task and accuracy collapses when it runs long. Over a few weeks the passes become automatic, at which point the skill transfers to their own written work as well — which is where it starts earning marks in papers that assess writing directly.

Where GrammarPrep fits

GrammarPrep's English strand includes proofreading items across the error types described here, and because the adaptive engine classifies mistakes by category it can show whether a child is losing marks to punctuation, to confusable words or to agreement — three problems that need three different fixes. That is the information a raw score cannot give you. Try the free taster for the question style, or the 15-minute diagnostic for a full English profile.
