TOEIC Decision Point

During vs While: Choose by Time Period or Action

In TOEIC Part 5, during and while often appear in sentences about meetings, repairs, training sessions, business trips, presentations, and service interruptions.

The fast choice is not “Can I explain the grammar?” The fast choice is: after the blank, do I see a time period/event, or something happening at that time?

During = time period or event. While = something happening at that time.

The 7-second choice

Do not translate the whole sentence first. Look immediately after the blank.

During

Use it when the sentence points to a time period or event: during the meeting, during business hours, during the inspection, during the renovation.

While

Use it when the sentence shows something happening at the same time: while the meeting is taking place, while the system is being repaired, while customers are waiting.

The signal to remember

During + event/time. While + something happens.

This is the MTC move. Do not name the grammar. Check the shape of the words after the blank.

Please turn off your phone during the presentation.
The signal is the presentation. It is an event. Choose during.
Please turn off your phone while the presenter is speaking.
The signal is the presenter is speaking. Something is happening. Choose while.
The shop will remain open during the renovation.
The signal is the renovation. It is a period/event. Choose during.
The shop will remain open while workers renovate the entrance.
The signal is workers renovate the entrance. Something is happening. Choose while.

What TOEIC wants you to notice

TOEIC often uses this trap in practical business sentences about meetings, conferences, repairs, inspections, training, travel, customer service, and office rules.

The trap is that both choices can feel like “〜の間” in Japanese. But TOEIC is checking whether you noticed what comes after the blank.

during the meeting / during the conference / during the inspection
A time period or event follows. Choose during.
during business hours / during the lunch break / during the holiday season
A time period follows. Choose during.
while the manager reviews the report / while the system is being updated
Something is happening at the same time. Choose while.
while customers are waiting / while employees are attending training
People are doing something at that time. Choose while.

Watch the small words

The words after the blank usually make the decision clear.

Choose during

Look for a time period or event: the meeting, the presentation, business hours, the inspection, the renovation, the trip.

Choose while

Look for something happening: the manager is reviewing, workers are repairing, customers are waiting, the system is updating.

This is not about explaining the sentence. It is about seeing whether the blank is followed by a time/event or by an action in progress.

Quick TOEIC check

Choose first. Then read the feedback. Use the one-second check: time period/event, or something happening?

1. Please keep your phone off ___ the presentation.

2. Please keep your phone off ___ the presenter is speaking.

3. The lobby will be closed ___ the renovation.

4. The lobby will be closed ___ workers replace the flooring.

The mistake fast readers make

Fast readers often translate both choices as “during” or “while” in Japanese and then choose by feeling. TOEIC uses that broad meaning as the trap.

Weak choice

Choose because both options seem to mean “〜の間” in Japanese.

Better choice

Look after the blank. Is it a time period/event, or is something happening?

This is the MTC move: avoid the grammar maze, find the signal, make the decision, and move on.

Why this mistake returns under pressure

Many test-takers know during and while during review, but still miss them in timed practice. The problem is often not the meaning alone. It is the speed of the signal check.

Under pressure, use the same move every time: look after the blank and ask whether you see a time/event or something happening.

1-second tool: time/event = during. Something happening = while.

Use small TOEIC mistakes as a diagnostic

If you know the answer after review but miss it during timed practice, the problem may not be the word alone. It may be your decision pattern.

FAQ (English) — During vs While What is the difference between “during” and “while” in English? “During” is followed by a noun. “While” is followed by a full sentence with subject and verb. When should I use “during” instead of “while”? Use “during” when you are referring to a time event like a meeting, class, or lunch — not an action. What comes after “while” in a sentence? “While” must be followed by a full sentence with a subject and verb, like “while he was speaking.” Can I say “during he spoke”? No. That’s incorrect. You must say “while he spoke” or “during the speech.” Is “while the meeting” correct English? No. “While” must be followed by a sentence. Use “during the meeting” instead. Is “during” used before nouns or verbs? Before nouns. Always. Example: “during the movie,” not “during watching.” Can I use “while” before a noun? No. “While” needs a full clause — it cannot directly follow a noun alone. Why is “during vs while” a common TOEIC trap? Because both relate to time and feel similar, but the grammar structures are completely different. How do I know if it should be “while” or “during”? Check what follows: if it's a noun, use “during.” If it's a sentence, use “while.” Is “during he was talking” correct? No. Use “while he was talking” or “during his talk.” What’s the rule for using “during” in TOEIC grammar questions? Use “during” before time-related nouns: “during the meeting,” “during lunch,” “during the event.” What’s the structure rule for “while” in TOEIC? “While” should be followed by a subject and verb: “while she was presenting,” “while we waited.” Can both “while” and “during” be correct in the same sentence? No. Only one will fit depending on whether it’s a noun or a sentence that follows. How do TOEIC questions trick learners with “during” and “while”? They hide the structure difference and use similar-looking choices. You must check grammar after the blank. What’s a simple way to check “during” vs “while”? If you see a verb after the blank, it’s probably “while.” If it’s just a noun, go with “during.” Can I use “during” with an action? Only if the action is made into a noun, like “during the presentation.” Not “during presenting.” Can I say “while lunch”? No. That’s incorrect. Say “during lunch” or “while we were having lunch.” Is “during the presentation” correct? Yes. That’s the proper use of “during” — followed by a time event. Can I say “I studied while the night”? No. “The night” is a noun. You should say “during the night.” Is “while he was talking” correct grammar? Yes. That’s the correct use of “while” followed by a subject and verb.
