A grammar error in CELPIP Writing costs more than a vocabulary gap. This checklist targets the five error patterns that most frequently prevent candidates from reaching CLB 9 on Linguistic Range and Accuracy.
Examples
Weak
Avoid"Yesterday I have went to the store and buyed some foods for my family."
Stronger
Better"Yesterday I went to the store and picked up a few groceries for the week."
How It Works
Subject-verb agreement
Singular subject needs singular verb; plural needs plural
"The committee has agreed" not "have agreed"
Consistent tense
Do not shift tense mid-paragraph without a time signal
"She arrived, sat down, and opened her laptop." — all simple past
Article accuracy
Use "a/an" for first mention, "the" for established referents
"I saw a dog. The dog was barking."
Preposition precision
Memorise high-frequency preposition collocations
"interested in" not "interested on"; "responsible for" not "responsible of"
Common Mistakes
Tense shift
AvoidI went to the mall and I am buying a jacket.
BetterI went to the mall and bought a jacket.
Fix: Keep the same tense throughout a narrative unless a time shift is explicit.
Article error
AvoidI need the advice from my manager.
BetterI need advice from my manager.
Fix: Uncountable nouns like "advice" rarely take "the" unless the referent is already established.
Subject-verb mismatch
AvoidThe group of employees are waiting.
BetterThe group of employees is waiting.
Fix: The head noun is "group" (singular), not "employees".

Tap a chunk to move it between the bank and answer area.
3. Sort it
Sort each item into the correct category.
Read each verb individually and confirm it matches the time signal.

Shift tense mid-paragraph without a time word to signal the change.
Why It Matters
CELPIP Linguistic Range and Accuracy at CLB 9 requires consistent control of complex grammar with only minor errors that do not impede communication. Candidates who reach CLB 9 on vocabulary but drop to CLB 7 on accuracy almost always make tense, article, or subject-verb errors that a 60-second grammar checklist would catch.
