Year 3-4 Common Exception Words: A Parent's Guide
Key takeaways
- The year 3-4 common exception words are a statutory list of around 100 spellings from the national curriculum, expected to be read and spelled by the end of Year 4.
- A 15-minute mixed-order diagnostic identifies the 20-30 words your child genuinely gets wrong, so practice targets gaps instead of re-drilling the whole list.
- Phonics cannot decode exception words, so look, cover, write, check practice builds the visual memory these words require.
- Sorting errors into phonically plausible versus jumbled changes what you practise: explanation fixes the first, repetition fixes the second.
- Year 3 practice should focus on building first memories of new words, while year 4 should shift to mixed review, speed and retention.
The year 3-4 common exception words are a statutory list of around 100 tricky words from the national curriculum that your child is expected to read and spell by the end of Year 4. Most practice fails because it treats all 100 as unknown. A 15-minute diagnostic finds the 20-30 your child actually gets wrong, so Thursday nights target those instead.
What are the year 3-4 common exception words and where does the list come from?
The year 3-4 common exception words are a statutory list of around 100 spellings set out in the English national curriculum for Key Stage 2. They appear in the Department for Education's English programmes of study: statutory spelling lists for years 3-4 and year 2, which every maintained primary school in England must follow.
They are called "common exception" words because they contain sounds written in unusual ways or ways children haven't been taught yet, so phonics alone doesn't reliably crack them. Words like "eight", "breath" and "particular" each break an expected pattern.
Schools typically send these words home as weekly spelling lists in the run-up to a Friday test, and many also weave them into look, cover, write, check practice. The full list is public, so you can work through it at home without buying anything; the terms that matter for any tool you use, including ours, are set out plainly at https://spellingnest.co.uk/terms.html.
Why do children still struggle with exception words after finishing phonics?
Phonics teaches children to decode by sounding out graphemes: the letter groups that map to sounds. That works for words like "chat" or "stone". It fails for words like "because", "people" and "again", where the spelling either uses a rare grapheme or breaks the pattern the child was taught. There is nothing to sound out, so decoding gives no purchase.
Exception words need a different route: look at the word, cover it, write it from memory, check it, and repeat until it sticks. That is the look, cover, write, check loop most parents remember from school, and it builds the visual memory phonics cannot supply.
The catch is that this route only works on the words your child does not yet know. Drilling the full block wastes evenings on words already mastered. A short diagnostic first narrows practice to the 20-30 genuinely unknown words, which is what a ten-minute session can actually cover (https://spellingnest.co.uk/how-spelling-sticks/).
How do year 3-4 words differ from the year 2 common exception words list?
The year 2 list is smaller and mostly irregular high-frequency words: people, because, friend, said. The year 3-4 statutory list is roughly double the size and shifts towards longer, less common words such as appear, breathe, certain, medicine and occasion. The DfE's spelling appendix places both lists in the same document, but the expectation changes: year 2 words are mostly decodable-with-a-twist, while many year 3-4 words carry silent letters, unstressed vowels or endings phonics never covers.
| Year 2 list | Year 3-4 list | |
|---|---|---|
| Approximate size | ~64 words | ~100 words |
| Word length | Mostly 3-6 letters | Often 6+ letters |
| Main difficulty | Unfamiliar graphemes (said, could) | Silent letters, unstressed vowels (answer, separate) |
| Test format | Single words, Friday test | Words in sentences, dictation |
In practice, year 2 practice is about memorising a handful of words a week; year 3-4 is about spotting patterns across a bigger set. Our FAQ covers how the diagnostic handles both lists.
Where year 5 and year 6 exception words fit
The same appendix carries a year 5-6 list of around 100 more words, including accommodate, conscience and rhythm. If your child has finished the year 3-4 block, the same diagnostic-first approach works: test first, then target the unknown words rather than re-drilling the whole list.
How can you quickly find out which exception words your child already knows?
Run a 15-minute diagnostic before any practice. Read the full year 3-4 list aloud in mixed order, three words at a time, and have your child write each one from memory. Mixed order matters: children memorise list position, and reciting "breath, breathe, busy" in order tells you nothing about whether they know "busy" on its own. Mark each word with no prompting between words, then sort the results into three piles: correct, nearly right, and nowhere near.
Sorting errors: phonically plausible vs not
The nearly-right pile is where the real information sits, so look at the spelling each child produced rather than just marking it wrong. A child who writes "peeple" for "people" has the sounds in the right order and is applying phonics sensibly; they need to learn that this word breaks the pattern, and a look, cover, write, check routine will usually fix it in a few sessions. A child who writes "peopl" or "poeple" has a different problem: the word's shape or letter order is unstable, and they need more repetition, often with letter tiles or by saying the letters aloud while writing. The distinction changes what you practise, because phonically plausible errors respond to explanation while jumbled ones respond to volume. Most children carry a mix of both, which is why a single style of practice rarely clears the whole list.
Turning the diagnostic into a shortlist of 15-20 words
Take everything from the wrong and nearly-right piles and cap the shortlist at 15-20 words. Anything above that dilutes practice; anything below means you can add a few from the Friday test as it comes home. Re-run the same dictation after a fortnight, keep the mastered words out, and promote new ones in. Spelling Nest does this sorting automatically: a short listen-and-spell check builds the shortlist and tracks which words are genuinely known, which is the part of the process most parents skip because it is fiddly to do on paper (https://spellingnest.co.uk/about/).
Which year 3-4 exception words cause the most mistakes and why?
A handful of words account for most of the errors on Friday test day. Because, people, and the could/should/would family trip children up because the letters they hear and the letters they write don't match. Homophones are the other big trap: there/their, where/were, and hear/here are all spelled correctly somewhere in the sentence, just not in the right slot.
Longer words bring a second problem: memory load. Separate, business, actually, and probably have four or more syllables, and children drop a middle syllable when they write them. Island and answer hide silent letters that phonics won't surface.
The fix is pattern-specific practice, not more repetitions of the whole list. Group the misses by cause (silent letters, homophones, dropped syllables), then run look, cover, write, check on each group, as described in phonics programme guidance (Sound Training phonics handbook). Our look, cover, write, check page (https://spellingnest.co.uk/look-cover-write-check/) sets this up with your child's own misses.
How should practice change between year 3 and year 4?
In year 3, aim for mapping and chunking. Your child is meeting most of the 108 statutory words for the first time, so split the list: test which ones they already know, then work through the unknown 20-30 in small groups by pattern or difficulty. Look, cover, write, check works well here because the goal is building a first memory of each word, not speed.
In year 4, the emphasis shifts to speed, retention and mixed review. By now your child should have met the whole list, so stop practising in list order. Shuffle the words, mix easy and tricky ones in the same ten-minute session, and add a short timed element so recall becomes automatic before the Friday test.
A practical split: year 3 spends most sessions on new words, year 4 spends most sessions revisiting words already marked as mastered. If a "mastered" word fails twice in mixed review, it goes back into the working set. That keeps practice honest and stops the same ten words resurfacing every test day.
What should you do if your child is still missing year 2 exception words in year 3 or 4?
Backfill quietly. Run a quick check over the year 2 list, pick the five or six words your child actually misses, and treat them like any other weekly list: flashcards on the fridge, look-cover-write-check at breakfast, letter tiles on the floor. Ten minutes, four days a week, beats an hour of Thursday-night misery.
Keep the tone neutral. Missing "said" or "because" in year 4 is a gap, not a failure, and children smell panic quickly. Rotate the gap words into the same practice session as this week's school spellings so nothing feels like remedial work.
When to talk to the teacher
If more than a dozen year 2 words are still unknown, or reading fluency is also wobbling, mention it at parents' evening and ask whether the school wants structured support alongside the weekly list. Tools like Sir Linkalot build mnemonic-based bundles around tricky words, and Spellzone (https://www.spellzone.com) maps courses by word type, so a teacher may already have a preferred route. Ask before buying; most schools will tell you what they use.
How do you build a ten-minute routine that actually sticks?
Pick a fixed slot tied to an existing habit, such as after breakfast or straight after school, and run the same shape every day: two minutes on this week's spellings, five minutes of look, cover, write, check, then three minutes of a different activity like listen and spell or letter tiles. Varying the activity matters more than extending the time; a short daily streak to Friday test day beats one long Thursday-night battle.
Honest comparison of practice tools, including where Spelling Nest falls short
Spelling Nest is built around exactly this routine: weekly lists, ten minutes a day, look-cover-write-check plus varied practice types, at £3/month or £20/year per family. Its limits are real: it only covers spelling, requires a UK billing address, and offers nothing for maths or reading, so a parent wanting one subscription across subjects will need something else alongside it.
Spelling Shed and Spellzone both cover a broader spelling curriculum, and Squeebles and Sir Linkalot take app-based approaches. If your child's school already subscribes to one of those, use it; the routine matters more than the tool.
FAQ
Is there a year 2 common exception words worksheet I can use to check gaps before starting year 3 words?
You don't need a worksheet. Write the year 2 list of roughly 64 words into a mixed-order dictation, three words at a time, and have your child spell each from memory. Sort the results into correct, nearly right, and nowhere near. The five or six misses become your backfill shortlist alongside the year 3-4 words.
How many of the year 3/4 common exception words should my child know by the end of year 4?
All of them. The statutory list of around 100 words is expected to be read and spelled by the end of Year 4. In practice, most children carry 20-30 genuine gaps at any point, which is why a short diagnostic first, then targeting those unknown words, works better than re-drilling the whole block every term.
Are common exception words the same as tricky words or red words?
Mostly, yes. Tricky words and red words are phonics-programme labels for words children can't yet decode reliably, and the statutory common exception lists are the curriculum's own version of that set. The difference is scope: a phonics scheme's tricky words are limited to what that scheme has taught so far, while the statutory lists cover all of Key Stage 1 and 2.
Do children get tested on year 6 common exception words at the end of primary school?
Not as a standalone spelling test. There is no national test that reads out exception words for children to spell. Spelling is assessed within the year 6 GPS papers and through teacher assessment of writing, where these words appear inside sentences and dictation. The year 5-6 list still matters because those words surface in writing across every subject.
What's the fastest way to practise exception words the night before the Friday test?
Skip the full list. Run a two-minute check over this week's words, mark the misses, and group them by cause: homophones, silent letters, dropped syllables. Then run look, cover, write, check on each group only. Ten focused minutes on six problem words beats an hour re-writing twenty words your child already spells correctly.
