Why Do My Tenses Keep Slipping?

You start a story in the past, and halfway through it sneaks into the present without you noticing. Teachers circle it a lot, and it's one of the most common notes in the margin of a piece of creative writing. But here's the good news: it's an easy fix once you know to watch for it. The whole skill comes down to a single habit — pick one tense and stick with it.

Why this happens to almost everyone

It's worth understanding why your tenses wander, because then it stops feeling like a personal failing. When you write a story, you can see the whole thing playing in your head like a film. Some of it feels like a memory (past); some of it feels like it's happening right now, live, in front of you (present). Your hand simply writes down whichever feeling is strongest at that second. So your verbs quietly drift between "then" and "now" — and because you know exactly what you mean, you don't spot it. Your reader isn't inside your head, though. All they get is the words on the page, and a paragraph that jumps from walked to sees to ran feels to them like a film with scenes missing.

The mistake

Watch the verbs jump around here:

• ✗ I walked into the room and see a huge cake. (past → present — slip!)
• ✓ I walked into the room and saw a huge cake. (both past)

Once you choose past or present, keep every verb in that same time zone — unless you have a real reason to change. Here are a few more of the same slip, so you can train your eye to catch it:

• ✗ She grabbed her bag and runs for the door. → ✓ She grabbed her bag and ran for the door.
• ✗ We were all laughing until Mr Price walks in. → ✓ We were all laughing until Mr Price walked in.
• ✗ The dog chased the ball and brings it back. → ✓ The dog chased the ball and brought it back.

Notice that in every fixed version, both verbs are wearing the same coat. That's the whole idea.

A second angle: which "clock" is the paragraph on?

Here's another way to think about it that some people find easier. Every paragraph is set on one clock — a story you're remembering runs on the past clock, while a running commentary of something happening right now (like describing a football match as you watch it) runs on the present clock. Before you write, decide which clock you're on. Then every main verb should tell that same time. If you catch a verb telling a different time with no reason, that's the one to fix. Most school stories run on the past clock, because you're telling something that already happened.

When it's actually OK to change

Now, changing tense isn't always wrong. You can — and sometimes should — switch when the time genuinely changes:

Yesterday we lost, but tomorrow we will win. (past, then future — correct, because the time really moves)

That sentence is fine, because the time really has moved from yesterday to tomorrow. The mistake is only when you slip by accident while you're still talking about the same moment. So the question is never "did I change tense?" — it's "did the time actually change, or did my hand just wander?" If a friend could read your sentence and ask, "Wait, is this happening now or did it already happen?", you've found a slip.

The fix: read it back, verb by verb

When you check your work, run your finger under each verb and ask, "Is this the same time as the last one?" A story told in the past should keep saying walked, saw, ran, felt — not suddenly see or run. This verb-by-verb check takes about thirty seconds on a paragraph, and it catches almost every slip before a teacher does. Try covering everything except the verbs and reading only those: walked... saw... ran... felt sounds steady, while walked... sees... ran... feels sounds like it's tripping over itself.

One tricky bit: the "before" moment

Sometimes, inside a past story, you need to mention something that happened even earlier. That's still allowed, and it doesn't count as a slip:

I was hungry because I had missed breakfast.

Both halves are in the past — was and had missed — you've just used had to show one thing happened before the other. Dip back to that "before" moment, then climb straight back to your main past story. The slip only happens when you accidentally hop into the present (am, is, sees, runs), not when you step further back into the past on purpose.

Why it matters

Getting this right is one of the quickest ways to make a story feel controlled and grown-up. When your tenses stay steady, the reader relaxes and just enjoys what's happening — they trust you're in charge of the telling. When the tenses wobble, they have to keep stopping to work out when everything is taking place, and that pulls them straight out of the story. In an exam, markers are actively looking for whether you can hold a tense across a whole piece, so a steady timeline can genuinely lift your mark. And it costs you almost nothing: one calm read-through, one finger under the verbs.

Quick check

Fix the slip in each one:

1. She opened the door and screams.
2. We were playing football when it starts to rain.
3. He picked up the pen and starts to write.
4. The crowd went quiet, then everyone cheers.
5. I was walking home when a fox runs across the path.
