One of the most common questions parents ask when preparing for 11 Plus exams is: “What exactly is tested in SPaG?” If you’ve ever flicked through a practice paper and found yourself wondering which rules matter (and which ones the examiners are really looking for), you’re not alone.
SPaG (or spelling, punctuation and grammar) can feel overwhelming because there’s so much to learn. But here’s the good news: SPaG is one of the most trainable areas of the exam. Unlike comprehension, which relies heavily on vocabulary, interpretation and instinct, SPaG is based on clear rules. Once your child understands those rules, and practises them enough, they can apply them quickly and reliably in the exam.
In this guide, we’ll take you through the essential SPaG topics your child needs to master for the 11 Plus. Think of it as a checklist, but with plenty of examples, practical tips and parent-friendly explanations. By the end, you’ll know exactly where to focus revision, to give your child the best chance of success.
What is SPaG in the 11 Plus?
SPaG stands for Spelling, Punctuation and Grammar. In the 11 Plus, it’s tested in one of two ways: either woven into longer comprehension and creative writing exercises, or as a standalone section — which is more common in multiple-choice papers such as those written by GL Assessment. In both cases, the goal is the same: to check whether children can apply the rules of English accurately and under pressure.
In the QE Boys 11+, for example, SPaG appears as a short, focused test made up of three mini-sections.
Your child might be asked to:
- Spot a spelling mistake in a sentence.
- Identify whether punctuation has been used correctly.
- Complete a sentence with the correct word or grammatical form.
Whatever grammar school you’re applying to, and no matter the format of the exam, SPaG is always important. It not only contributes directly to raw scores, but also strengthens reading fluency for comprehension and clarity of style in creative writing. In other words, strong SPaG skills underpin every part of English — which is why mastering them gives your child a crucial advantage.
What are SPaG skills for the 11 Plus?
When people talk about SPaG skills, they’re referring to the foundations of written English. These are:
- Spelling: Knowing how words are built, recognising common traps, and spotting when something “looks wrong.”
- Punctuation: Using commas, apostrophes, quotation marks and other marks correctly.
- Grammar: Understanding the rules that hold sentences together, including verb tenses, agreement and word classes.
Mastering these skills isn’t just about high scores in the 11 Plus. Children who are confident in SPaG find comprehension easier (because they can untangle tricky sentences) and write more clearly (because they understand how to structure ideas). But the benefits go much further.
Strong SPaG underpins almost every aspect of secondary learning, from constructing clear arguments in history, to writing up science experiments accurately, to presenting ideas persuasively in essays and debates. In short, good SPaG is a skill for life.

Essential 11 Plus SPaG Topics: What To Focus On
Here’s where we get into the details.
Below are the 10 SPaG topics every child should know before sitting the 11 Plus. Some are straightforward, others are trickier, but all of them come up regularly in exams.
We’ve also included sample questions from Achieve Learning 11+ papers, to help you get a true feel for the exam.
1. Spelling rules and tricky words
Spelling is one of the simplest areas to practise, but also one of the easiest to lose marks on.
In 11+ SPaG tests, children often see a full sentence with one word spelled incorrectly. Their job is spotting the mistake (if there is one). The challenge is that examiners choose words that “look” right. So children can’t just rely on their instincts.
Key areas to revise:
- Homophones: Words that sound the same but are spelled differently, like there/their/they’re, its/it’s, practice/practise.
- Irregular spellings: Words like separate, rhythm, embarrass, accommodate. These don’t follow standard patterns.
- Suffixes and prefixes: Especially -ible/-able, -ence/-ance, -ise/-ize.
You’ll find lots of spelling lists online (featuring irregular spellings or specific rules), but to prepare thoroughly, practise with sentences rather than just lists. This mirrors the format of 11 Plus SPaG tests and trains children to scan carefully.
For instance, which word is incorrect here?

2. Apostrophes
Apostrophes are small punctuation marks, but they cause big problems!
Children must know (and confidently use):
- Contractions: don’t, can’t, won’t, you’re etc.
- Possession: the boy’s bag (one boy), the boys’ bags (more than one boy).
The most common 11 Plus trap is not spotting a missing apostrophe. So here, practice makes perfect! When going over the rules, ask your child to explain why an apostrophe is (or isn’t) correct. Being able to explain the rule is just as important as spotting the error.
3. Commas
Commas are tested in multiple ways in the 11 Plus. Children should know how to use commas:
- In lists: We packed sandwiches, water, and fruit.
- After fronted adverbials: After the storm, the sun came out.
- Around clauses: The car, which was red, sped past.
- To avoid comma splices: A comma splice is when two full sentences are joined with just a comma (It was late, we went home). Children should know this is incorrect, and that the sentences need separating with a full stop, semicolon, or conjunction.
- As part of dialogue and speech tags: “I’m coming with you,” said Anna. The comma separates the spoken words from the reporting clause, and this is a frequent test point.
In the most challenging 11 Plus exams, comma placement around speech is a favourite trick. For example, what’s the problem here?

Parent tip: Encourage your child to read the sentence aloud. If they naturally pause, there may need to be a comma — but also remind them that not every pause equals a comma.
4. Colons and semicolons
These higher-level punctuation marks don’t always appear in every 11 Plus exam, but they are common in harder tests like QE Boys.
The two key rules to know are:
- Colons introduce something, usually a list or explanation: You will need: a pen, paper and a ruler.
- Semicolons link two related sentences: He was tired; he kept going.
For instance, what’s the mistake here?

Parent tip: If your child is applying to a highly selective school like QE Boys or Henrietta Barnett, make sure they know the difference. These skills are frequently tested, so it pays to be prepared.
5. Speech punctuation
Speech punctuation often trips children up because it’s fiddly. We’ve already seen it in relation to commas, but there are a few more rules to learn.
Children need to know that:
- Quotation marks go around spoken words.
- Punctuation comes inside the quotation marks if it’s part of the speech. “I can’t believe it!”
- Punctuation comes outside the quotation marks if it’s part of the rest of the sentence. Did she really say “I can’t believe it”?
- The reporting clause (e.g. said Tom) doesn’t start with a capital unless it’s a new sentence. “I’m ready,” said Tom.
- A comma is needed before the reporting clause (e.g. before said). “I’m ready,” said Tom is correct — not “I’m ready” said Tom.
- When the speech tag comes first, it’s followed by a comma before the quotation marks. For example: Tom said, “I’m ready.”
Parent tip: Practise with lots of short dialogue sentences. Get your child to mark up mistakes (and keep repeating the exercise!), as this is a frequent exam question.
6. Verb tenses
Tense errors are common in 11 Plus SPaG tests. They feature in “Sentence Completion” sections, where children must select the most appropriate word or phrase to finish a passage.
As part of this, they should be confident with:
- Simple tenses: past, present, future.
- Perfect tenses: I have eaten, she had gone.
- Progressive tenses: I am running, they were talking.
- Consistency across a passage: Avoiding sudden shifts in tense, e.g. She was walking down the street and suddenly runs into her friend.
- Irregular verbs: Forms like swim/swam/swum or go/went/gone, which don’t follow predictable rules.
For example:

Parent tip: Ask your child to rewrite incorrect sentences so they see how the tense should match. This mirrors the exam structure and strengthens long-term recall.
7. Subject–verb agreement
This is a subtle but important rule. The verb must match the subject, not the nearest word.
- Incorrect: The group of boys are playing.
- Correct: The group of boys is playing.
Exams often include distracting nouns between the subject and verb to trip children up.
Parent tip: Teach your child to find the subject first. Then check the verb. This prevents them from being distracted by extra words in the middle.
8. Sentence fragments and run-ons
At harder grammar schools, including QE Boys, children may be asked to spot incomplete or incorrectly joined sentences.
- Fragment: Because it was raining. (not a full sentence).
- Run-on: It was raining he stayed inside. (missing punctuation).
Parent tip: Encourage your child to ask: “Does this sentence have both a subject and a verb? And if it’s two ideas, are they joined correctly?”
9. Word classes
This is one of the most tested areas in the 11 Plus. Children need to be able to confidently identify the nine main word classes: nouns, verbs, adjectives, adverbs, pronouns, interjections, determiners, prepositions and conjunctions.
The tricky part? Word classes can change depending on context.
- Light (noun): The light was dim.
- Light (verb): Please light the fire.
- Light (adjective): The bag was light.
Examiners love these so-called “chameleon words” because they force children to think about how a word is being used in the sentence, not just what it usually means. These questions crop-up in comprehension too.
Parent tip: Practise with everyday “chameleon words” (like play, watch, match, run) and get your child to use them in different sentences. This not only builds accuracy for the test but also strengthens overall grammatical confidence.
At Achieve Learning we’ve created SPaG-only practice papers with dedicated word class sections, as well as mixed comprehension + SPaG papers where word class questions appear in context. Both give your child realistic, exam-style practice.
10. Vocabulary and sentence completion
Last but certainly not least, sentence completion questions bring together grammar and vocabulary. Children are asked to choose the best word to complete a sentence, often with several close options.
For example:
Parent tip: Wide reading is the best preparation here, with a mix of challenging classic and modern texts. The more words your child encounters (and uses regularly and confidently), the easier it is to choose the precise meaning in context.

How to Revise SPaG for the 11 Plus: Revision Strategies
One of the biggest misconceptions parents have is that SPaG can be crammed at the last minute. Unlike maths, where children might suddenly “get” a method, SPaG is all about applying rules accurately and consistently. That kind of accuracy only comes with repetition and steady practice.
But the good news is, you don’t need marathon sessions. Little and often is most effective.
Here are some practical revision strategies that work:
- Daily drills: Just ten minutes a day makes a huge difference. Focus on one rule at a time: apostrophes on Monday, commas on Tuesday, verb tenses on Wednesday. Short bursts (focusing on the most common mistakes) keep knowledge fresh without overwhelming your child.
- Error spotting: Children learn best when they can see rules applied in real sentences. That’s why 11 Plus SPaG practice papers are so powerful. They replicate exam conditions and train your child to spot mistakes in context, not in isolation.
- Timed papers: In the exam, speed is just as important as knowledge. Many children can ace a worksheet at home when there’s no clock ticking, but fall behind under pressure. Build stamina with full 11+ SPaG test papers, setting a timer so your child gets used to the pace.
- Reviewing mistakes: Don’t just mark answers right or wrong. Sit with your child and ask, “Why was that wrong?” or “Which rule applies here?” This deepens understanding and helps them avoid the same mistake twice. That’s why we always include a full glossary and parent-friendly explanations.
Final Thoughts: Why SPaG Matters for the 11 Plus
SPaG is sometimes overlooked as “just the technical bit of English,” but in truth, it’s often the area that separates top candidates from the rest. Losing one or two marks on an apostrophe, a tense shift or spelling error might not feel like much, but in competitive grammar schools, those marks can make all the difference.
But SPaG is also one of the fastest areas to improve. Once your child has mastered the rules, their confidence grows quickly, and that accuracy carries through into every other area of their learning.
At Achieve Learning, we’ve created bespoke resources to guide families through this process:
- SPaG-only packs for focused daily revision.
- Full-length 11+ practice papers (Comprehension + SPaG) to build stamina and exam technique.
- Bespoke 1-1 tuition and realistic mock exams to target weak spots and build confidence under pressure.
With the right preparation, your child will walk into the 11 Plus confident in their SPaG skills, ready to achieve their best.
