Year 5 Conventions of Language: spelling, grammar and punctuation get busier
Conventions of Language is the same three-part test your child sat in Year 3: spelling, grammar and punctuation, all on screen. What changes at Year 5 is where the error is hiding. Sentences are longer, the wrong word is buried further in, and a question is as likely to ask whether a whole sentence works as it is to ask about one word in it.
The step up is real but it is a step, not a leap: the same skills your child built in Year 3 are still being tested, just inside busier sentences and with less obvious cues.
What does Year 5 Conventions of Language cover?
| Topic | What it looks like at this year level |
|---|---|
| Spelling | The sentence gets longer before the error appears, and Suffixes and prefixes, Double letters and Silent letters start carrying real weight alongside Homophones like affect and effect. |
| Grammar | Grammar starts asking whether a whole sentence works, not just whether one word is right: Clause and sentence structure tests genuinely complete sentences, and Modality asks how certain or how strong a sentence actually sounds. |
| Punctuation | Apostrophes move on to plural ownership, like the girls' bags, and Quotation marks and direct speech and Commas start carrying marks of their own rather than being an afterthought. |
The test is still fully online and adaptive, the same as every other year level, so a run of harder questions partway through is a sign your child is doing well, not a sign something has gone wrong. Spelling is still tested by proofreading a sentence rather than by writing a dictated word, but the sentences are noticeably longer now, and the misspelled word is rarely the obvious long one. Grammar is the section that has changed the most since Year 3: instead of mostly labelling a part of speech, several questions now ask your child to judge a whole sentence, which is a harder and more useful skill.

Get startedSample Year 5 Conventions of Language questions
These are original questions written in the style of NAPLAN. Real test questions are ACARA copyright and are not published for practice use.
Spelling
One word in this sentence is spelled incorrectly. Write the word correctly. The wind had a strong affect on the sails.
Answer: effect
"Effect" is the noun, the result of something. "Affect" is the verb. This noun/verb pair is one of the most common Year 5 homophone traps.
Grammar
Which word correctly completes the sentence? Each of the players ____ a numbered shirt.
Answer: wears
The subject is "each", which is singular, even though "players" sits right next to the verb. This is the classic nearby-noun trap.
Punctuation
Which sentence uses the apostrophe correctly?
Answer: The girls' bags were left on the bus.
More than one girl owns the bags, so the apostrophe goes after the plural s, not before it. This is where Year 5 apostrophe questions move beyond Year 3's single-owner form.
Grammar
Which word makes it CERTAIN the bus will arrive? The bus ____ arrive at nine o'clock.
Answer: will
"Will" is a promise. "Might", "could" and "may" all leave room for doubt. Modality questions test how sure a sentence sounds, not just grammar rules.
Common Year 5 conventions mistakes
Confuses noun and verb spellings
Uses the noun spelling where the verb is needed, or the reverse, as in "I need to practice my spelling" or "the affect of the storm".
Fix
Teach the pattern with a pair a child can hear the difference in, like advice and advise, then have them test the sentence by substituting that pair to hear which form fits.
Treats everyone, each and nobody as plural
Gives words like "everyone", "each" and "nobody" a plural verb, writing things like "everyone have finished" or "each of the players wear".
Fix
Teach that these words mean "every single one" and take a singular verb. Substituting "every single person" into the sentence out loud makes the singular verb the one that sounds right.
Always places the apostrophe before the s
Writes "the girl's bags" when several girls own the bags, never moving the apostrophe after the s when there is more than one owner.
Fix
Teach the two-step habit: write the owner word in full first (girl or girls), then add the apostrophe straight after it. Asking "how many owners?" before writing anything decides the whole answer.
Joins two whole sentences with a comma
Uses a comma where a full stop or a joining word belongs, writing something like "it was late, we went home".
Fix
Teach the stand-alone test: if both halves of the sentence could be their own sentence, a comma alone cannot join them. They need a full stop, a joining word like "so" or "because", or a semicolon.
How to practise for Year 5 Conventions of Language
Practise reading a whole sentence before answering, not just the part around the gap or the underlined word. At Year 5 the trap is very often built into a word two or three away from where the question is pointing.
Homophones are worth deliberate attention now: affect/effect, practice/practise and their/there/they're all start appearing, and they are learned through meaning, not sound. Attach a short meaning cue to each spelling rather than trying to memorise the letters.
Since apostrophes now cover both one owner and several, a five-minute drill sorting real sentences into "one owner" and "more than one owner" before placing the apostrophe fixes more marks than a rule recited from memory.
When is the Year 5 NAPLAN in 2027?
The 2027 window is Wednesday 10 March to Monday 22 March 2027. Schools schedule the four tests inside that window, and Writing has to be scheduled for the first day. Most schools finish in the first week, so confirm the exact days with your school rather than a national site.
On the day, Conventions of Language at Year 5 runs for 45 minutes.
Test structure, marking and reporting facts on this page come from ACARA's public NAPLAN documentation, checked against nap.edu.au in August 2026.

The gap between Year 3 and Year 5 conventions is mostly about longer sentences hiding familiar errors, and that is a gap practice closes quickly.
