Using tenses in academic writing

The way we use tense can differ between formal, academic English and spoken English. These differences reflect different writing styles. Read on for a quick guide of what tense to use where in your academic writing.

Simple tenses


General truths or states

Habitual actions

The ISO standards are regularly reviewed.

Refer to the plot in novels, cinema and other stories

Cite an author or to refer to what an author says

Present your interpretations (opinions) and the interpretations of others

To describe diagrams and figures

An action started and finished in the past

Dulay and Burt conducted their studies in the early seventies.

Methods and results of an investigation or experiment

Samples were centrifuged then strained.

Tip: Abstracts are written largely in past tense because they report on an investigation.


Inform about a future event or predict a future event

Tip: ‘Going to’ is considered informal and rarely used in academic writing.  Use such expressions such as 'is likely to' or 'is certain to' instead.

Present Perfect

Actions that started in the past and have not finished

When information established in the past is still relevant and current

Past Perfect

A past event that clearly happened before another past event

Progressive (continuous) tenses


Actions that are temporary around the present time

Tip: Several verbs rarely if ever use continuous tenses. This webpage on continuous tenses and meaning explains further.

  • It seems unlikely. (correct)
  • It is seeming unlikely. (incorrect)


A continuous activity which provides background to a single event

Passive voice

To put the focus of the sentence on the new or important information

To remove the person who does the action, who may not be of interest

Final tips

Keep tenses consistent within your text: the same context usually requires the same tense.

1. Tenses can change in a sentence if the context changes

Cells divided within 20 minutes and will continue to divide until frozen.

The sentence above talks about both the past and the future context of the cells, and this is perfectly acceptable.

2. When changing tenses in a paragraph, use ‘signalling words’ or time phrases

since then, currently, now, in the past / future
