What Is Academic Writing? Style Guide

Academic writing is the formal, evidence-based style researchers, educators, and students use to communicate ideas and findings within a scholarly community. It is defined less by its subject matter — a chemistry paper and a literature-review essay both count — than by a shared set of conventions: a formal register, a reliance on cited evidence over personal opinion, and a structure built to let a reader evaluate an argument rather than just follow a narrative.

This page defines academic writing and its core stylistic conventions. It is deliberately about register — the tone, grammar, and word-level choices that mark a text as scholarly — not about how a paper’s sections are organized. For that, see CASRAI’s Parts of a Research Paper guide and the IMRaD Structure entry.

The core characteristics of academic writing

Across disciplines and style guides, a few traits recur consistently:

Formal. Academic writing avoids contractions, slang, and colloquial phrasing. “Do not” rather than “don’t”; “researchers found” rather than “researchers discovered, interestingly.”
Objective. Claims are framed around evidence and argument rather than personal feeling, typically favoring a third-person voice over first-person opinion (though first person is increasingly accepted for describing a study’s own methodological choices — see the style-manual section below).
Precise. Word choice is specific rather than approximate. A paper reports “a 12% reduction,” not “a big drop”; it names the instrument, the sample, and the method rather than gesturing at them.
Hedged, not overstated. Because a single study rarely proves a claim outright, academic prose uses cautious language — “suggests,” “is associated with,” “may indicate” — instead of sweeping certainty. CASRAI’s Hedging in Academic Writing guide covers this convention in depth.
Evidence-based and cited. Every substantive claim traces back to a source, using the citation format the target journal or discipline specifies (APA, AMA/Vancouver, Chicago, and others each have their own rules).
Structured and cohesive. Ideas build in a deliberate order, signposted with explicit transitions and consistent terminology rather than left for the reader to infer. See Cohesion and Coherence in Academic Writing and Signposting Language in Academic Writing.

The style manuals behind the conventions

“Academic writing style” is not one fixed rulebook — it is set, discipline by discipline, by a small number of style manuals that journals and universities adopt as house style:

APA Style (Publication Manual of the American Psychological Association, 7th edition) governs most psychology and social-science writing — author-date citations, specific formatting for verb tense and voice, and explicit guidance to favor active voice for clarity where the sentence allows it.
The AMA Manual of Style (11th edition) is the dominant reference across biomedical journals, using a numbered citation system and its own rules for abbreviations, units, and statistical reporting.
The EASE Guidelines for Authors and Translators of Scientific Articles, published by the European Association of Science Editors, take a discipline-agnostic, plain-language approach and include guidance specifically aimed at researchers writing in English as an additional language — addressing the phrasing and structural issues that most often arise in translation.

A given journal will specify which manual governs submissions; the underlying goal across all of them is the same — formality, precision, and traceable evidence — even where the mechanical rules (citation format, number formatting, verb-tense conventions) differ.

Types of academic writing

Academic writing spans a range of formats, generally falling into two broad categories:

Student writing — essays, lab reports, theses, and dissertations, written primarily to demonstrate comprehension and analytical skill to an instructor or committee.
Expert/scholarly writing — journal articles, conference papers, monographs, and grant proposals, written to introduce new findings or argument to a field of specialists and to withstand peer review.

Within both categories, the underlying rhetorical modes recur: descriptive writing (reporting facts, e.g. a methods section), analytical writing (identifying relationships and patterns, e.g. a results section), and argumentative/critical writing (evaluating evidence and taking a position, e.g. a discussion section or a thesis statement). Most real academic documents combine all three within a single piece rather than using just one throughout.

How academic writing differs from other writing

Academic writing is often defined by contrast:

Vs. professional/business writing. Professional writing (a memo, a grant status report, a business case) is typically shorter, action-oriented, and written for a reader who wants a conclusion up front. Academic writing builds its case methodically and defers conclusions until the evidence has been laid out — the inverse of a business “bottom line first” structure.
Vs. journalistic writing. Journalism favors accessible, punchy prose and rarely uses in-text citation for every claim. Academic writing accepts denser, more qualified sentences in exchange for precision and traceability.
Vs. creative or general writing. Figurative language, first-person narrative voice, and rhetorical flourish — normal in creative nonfiction — are minimized in academic prose in favor of a consistent, restrained register.

This is also why generic grammar or writing-improvement tools only partially fit the job: they check whether a sentence is grammatically correct, not whether it hedges appropriately, cites correctly, or matches a target journal’s house style — the specifically academic conventions covered throughout this page and its linked guides.

Academic writing style vs. manuscript structure

It’s worth being explicit about a distinction that’s easy to blur: academic writing style (this page) is about register — word choice, tense, formality, hedging, cohesion. Manuscript structure is about section-level organization — what goes in the Introduction versus the Discussion, in what order, under what headings. CASRAI covers structure separately: see Parts of a Research Paper for the full section-by-section map, and the IMRaD Structure entry for the Introduction–Methods–Results–Discussion pattern that organizes most empirical papers. A paper can follow IMRaD structure perfectly and still fail on style (inconsistent tense, unhedged claims), or vice versa — they are separate skills.

And for the structural side of a manuscript rather than its register: Parts of a Research Paper, How to Write the Introduction Section, How to Write a Methods Section, How to Write the Results Section, and How to Write a Conclusion for a Research Paper.

Frequently asked questions

What is an example of academic writing?

A peer-reviewed journal article, a doctoral dissertation, a conference paper, and an undergraduate research essay are all academic writing — they differ in audience and stakes, but share the same formal, evidence-based, cited register described above.

What are the main types of academic writing?

Most academic documents combine three rhetorical modes: descriptive (reporting facts, as in a methods section), analytical (identifying patterns and relationships, as in a results section), and argumentative or critical (evaluating evidence and taking a position, as in a discussion section or thesis). Few real documents use only one mode throughout.

What is an academic writing style?

“Academic writing style” refers to the register conventions covered on this page — formality, objectivity, hedged rather than absolute claims, precise and discipline-specific vocabulary, and consistent citation — as codified by a governing style manual (commonly APA, AMA, or discipline-specific journal house style).

How is academic writing different from other writing?

It is more formal and evidence-dependent than business or journalistic writing, defers its conclusions until evidence has been presented rather than leading with them, and is governed by a specific style manual’s rules on citation, tense, and terminology rather than by house style alone.
