11+ Punctuation Guide: How to Spot Every Mistake in the English Paper

How the Punctuation Section Works

The punctuation section of the 11+ English paper, including the Kent Test, looks a lot like the spelling section. Your child sees a sentence or short passage split into lettered sections. Somewhere in it there is one punctuation or capital letter mistake, or no mistake at all. They find the section that holds the error and mark its letter on the answer sheet, or mark N if everything is correct.

For example, a sentence about George III might be missing a closing bracket. Once your child has found where the bracket should go, they check which lettered section that falls in, perhaps A, and mark A clearly on the answer sheet.

It sounds simple, but these questions are designed to catch children out. A clear method makes a big difference to their score.

Step One: Build a Punctuation Toolbox

Before your child can spot a mistake, they need to be able to recall every type of punctuation that could come up. A good habit is to write out a “toolbox” at the top of the punctuation page at the start of the section:

With the list written down, your child doesn’t have to hold it all in their head, and it acts as a checklist when they get stuck.

Tip: Knowing the names of the punctuation marks isn’t enough. Your child needs to know the rules for using each one. If they are unsure about apostrophes or inverted commas, build targeted practice on those into your revision plan well before the exam.

Step Two: Learn the “Box of Tricks” Technique

The key point to understand is that there are two kinds of mistake:

1. Incorrect punctuation, where a mark is on the page but is wrong. This is usually easier to spot.
2. Missing punctuation, where a mark should be there but isn’t. This is harder, because there’s nothing on the page to catch the eye.

With that in mind, here is the step-by-step technique:

1. Read the sentence through. If your child is completely sure where the mistake is, they mark it and move on.
2. Check the toolbox. If they aren’t sure, they look at their list. Could a semicolon be missing? Has a bracket been left open?
3. Use deduction. They work through each section and cross off any that are definitely correct. If they end up guessing, they are choosing between fewer options.
4. Trust your gut. If they are still unsure, they go with their instinct, and remember that the answer could be N.

Worked Examples

Spotting a Missing Apostrophe

Its going to be so strange in August because my brother is moving to university.

• August has a capital letter, which is correct because it’s the name of a month.
• university has no capital. Children sometimes think it needs one, but it isn’t naming a particular university, so lower case is correct.
• brother my doesn’t need any punctuation between the words.
• The full stop at the end is fine.

That leaves “Its”. Try the swap test: “It is going to be so strange…” The sentence still makes sense, so the word needs an apostrophe: it’s. The mistake is missing punctuation in section A.

Tip: The “it is” swap test works every time. If it is or it has fits, write it’s. If it doesn’t fit, write its.

Using a Two-Step Check

For harder questions, refine the method into two passes:

• Pass 1: Check every mark that is already there. Is each one correct?
• Pass 2: If nothing is wrong, look for anything that is missing.

Take a sentence mentioning Crowsville Theme Park. All three words have capital letters, and that’s correct because together they name a specific place. “Theme park” on its own wouldn’t need capitals. Later in the passage, though, a colon appears where it doesn’t introduce a list, an explanation or a quotation. That is the error.

There’s no shortcut here. A child who knows how colons work spots it straight away. A child who is unsure will struggle, so it’s a sign they need to revise the rules for that mark.

Finding a Missing Comma

After the dog almost escaped from the garden fences have been installed.

On Pass 1, the only punctuation is a capital letter and a full stop, and both are correct. So the mistake must be missing punctuation.

“After” is a conjunction at the start of the sentence, which usually means two clauses that need a comma between them. Reading the sentence aloud helps: “After the dog almost escaped from the garden, fences have been installed.” There is a natural pause after garden.

This question is a trap because “garden fences” is a common phrase, so it’s easy to read straight past the gap. Reading with expression shows where the comma belongs.

Did you know? Our brains are good at “hearing” where commas go. Reading a sentence aloud, or in your head with expression, often shows the natural pause where one clause ends and the next begins.

When There Is No Mistake

The hardest questions often contain lots of punctuation that is all correct. Take a line of speech like this:

“You should wear your coat,” said Katie. “It’s incredibly cold outside!”

Go through each mark in turn. The opening inverted commas are correct. The comma before the reporting clause is correct, and so are the closing inverted commas. Katie has a capital letter because it’s a name, and the full stop after said Katie is correct. The new inverted commas open her second piece of speech. It’s passes the swap test (it is incredibly cold), the exclamation mark suits her tone, and the closing inverted commas end the speech.

Nothing is wrong and nothing is missing, so the answer is N. Your child should mark it confidently and move on.

Common Pitfalls to Avoid

• Assuming there must be a mistake. N is a real answer, so don’t change something that is already correct.
• Capitalising common nouns. Words like university, school and park only need capitals when they’re part of a proper name.
• Only looking at what’s on the page. Missing apostrophes and commas lose the most marks.
• Rushing speech punctuation. Check each inverted comma, comma and capital letter one at a time.

Reading widely helps with all of these. Children who read a lot see correct punctuation in context every day. Our guide to reading comprehension skills and strategies has ideas for making reading time count, and Building Vocabulary for the 11+ English Exam covers the word knowledge that supports every part of the paper.
