TL;DR

• Acknowledgements credit non-authors who helped but do not qualify for authorship.

• Authorship requires intellectual contribution; assistance alone does not qualify someone.

• Name specific contributions, not just people, in your acknowledgements section.

• Funding bodies, technical helpers, and peer reviewers each need different language.

• Most journals have explicit acknowledgement guidelines — always check them first.

You finish your paper. You have your authors listed. But three other people helped you get there. Your school librarian tracked down a hard-to-find source. A university professor gave you thirty minutes of feedback. A family friend ran your statistics through software you did not have access to. None of them wrote the paper. None of them designed the study. Do they belong on the author list? Almost certainly not. Do they deserve recognition? Absolutely.

This is the question that trips up first-time researchers more than almost any other. The line between authorship and contribution is not always obvious. Getting it wrong can mean either leaving out someone who deserves credit or, more seriously, adding someone to an author list who does not meet the criteria. Both are problems. Both are avoidable.

Understanding how to acknowledge contributors who are not authors is a core publishing skill. It protects the integrity of your paper, respects the people who helped you, and signals to editors that you understand research ethics. Here is how to do it correctly.

What Is the Difference Between an Author and a Contributor?

An author is someone who made a substantial intellectual contribution to the research, participated in drafting or critically revising the work, approved the final version, and takes accountability for the work. A contributor is someone who helped in a meaningful but more limited way, without meeting all of those criteria.

The most widely used authorship standard in academic publishing comes from the International Committee of Medical Journal Editors (ICMJE). Their criteria state that authorship requires all four of the following: substantial contribution to conception or design, or to data acquisition, analysis, or interpretation; drafting the work or revising it critically for important intellectual content; final approval of the version to be published; and agreement to be accountable for all aspects of the work. Someone who only collected data, only provided equipment, or only gave general supervision does not meet this standard under ICMJE guidelines. They belong in the acknowledgements section, not on the author line.

This distinction matters because authorship carries responsibility. If a paper is later found to have errors, all authors are expected to answer for it. Listing someone as an author when they cannot fulfil that responsibility is called honorary or gift authorship, and it is considered a breach of research integrity by bodies including the Committee on Publication Ethics (COPE).

If you are navigating the submission process for the first time, understanding the full publication workflow will help you see where acknowledgements fit within the broader structure of a research paper.

How to Acknowledge Contributors Who Are Not Authors: The Core Structure

The acknowledgements section is short, specific, and placed after the main text, usually before the references. It names individuals and organisations that contributed to the work in ways that do not qualify them for authorship. The key principle is specificity. Do not write "we thank everyone who helped." Name the person, name what they did.

A standard acknowledgements section covers three categories of non-author contribution:

1. Individuals who provided technical or practical assistance. This includes people who helped with data collection, laboratory procedures, statistical analysis, language editing, or software access. Name them and describe the specific help they gave. For example: "The authors thank Dr. Sarah Osei for assistance with statistical analysis using SPSS version 29."

2. Funding sources and institutional support. If your research received any funding, a grant, a school stipend, or access to institutional resources, name the funding body and the grant number if one exists. Many journals require this. The Nature Portfolio journals, for instance, explicitly state in their submission guidelines that funding information must appear in a dedicated funding statement, sometimes separate from the general acknowledgements.

3. Peer reviewers and editors (when appropriate). Some journals encourage authors to thank peer reviewers by name if the review was not blind, or to acknowledge the editorial team. Check the specific journal's policy before doing this, as conventions vary.

If you are working on your first submission and want structured guidance on how to prepare each section of your paper, Publication Compass is a platform built to walk student researchers through exactly this kind of process, including feedback on your acknowledgements before you submit.

How to Phrase Acknowledgements Correctly

Academic acknowledgements follow a consistent register. They are formal, brief, and specific. The phrasing varies slightly by discipline, but the following conventions apply across most fields.

Use past tense and passive or active constructions that describe what was done, not who is wonderful. "We thank X for providing access to Y" is correct. "We are deeply grateful to the incredible X whose support made this possible" is not appropriate for a research paper. Save that for your diary.

Do not thank people for things they did not do. If a teacher simply encouraged you, that is kind, but it does not belong in a formal acknowledgements section unless they gave substantive feedback on the work itself. Vague thanks inflate the section and reduce its credibility.

Always obtain permission before naming someone in your acknowledgements. This is standard practice recommended by COPE. Naming someone implies they endorse the work. Give them the chance to review the relevant section and confirm they are comfortable being listed.

For student researchers submitting to journals like the Journal of Emerging Investigators or Cureus, both of which publish student and early-career work, the acknowledgements section is reviewed as part of the submission. Editors look for appropriate attribution. A missing or vague acknowledgements section can signal inexperience with publication norms.

Common Mistakes When Acknowledging Contributors Who Are Not Authors

Several errors appear repeatedly in student submissions. Knowing them in advance will save you a revision request from an editor.

The first mistake is omitting the acknowledgements section entirely. Some first-time authors assume it is optional. For many journals, it is required. Even where it is not mandatory, its absence is noticed.

The second mistake is listing contributors as authors when they do not qualify. This is the more serious error. If a mentor reviewed your draft but did not contribute to the intellectual design of the study, they should be in acknowledgements, not on the author line. Discuss this with them directly. Most experienced researchers understand and respect the distinction.

The third mistake is failing to disclose funding. If you received any form of support, financial or material, and you do not disclose it, that is a transparency problem. Journals including those published by PLOS and Springer Nature have explicit policies requiring full funding disclosure. Check the author guidelines for whichever journal you are targeting before you write this section.

To find journals that are the right fit for your paper's scope and your level of experience as a researcher, joining the waitlist for Publication Compass gives you early access to a platform designed to match student research with appropriate peer-reviewed outlets.

A Step-by-Step Process for Writing Your Acknowledgements Section

Writing a clean acknowledgements section takes less than an hour if you approach it methodically. Here is a reliable sequence to follow:

1. List every person who contributed to the project in any way. Include everyone, even if you are not sure they qualify for acknowledgement.

2. For each person, write one sentence describing exactly what they did. Be specific. "Assisted with data collection in March 2024" is better than "helped with the research."

3. Apply the ICMJE authorship criteria. Anyone who meets all four criteria belongs on the author list, not in acknowledgements. Everyone else stays in your working list.

4. Check your target journal's author guidelines for any specific acknowledgements requirements. Look for word limits, required subheadings such as a separate funding statement, and any formatting instructions.

5. Contact each person you plan to name and confirm they consent to being acknowledged and that your description of their contribution is accurate.

6. Write the final section using formal, specific language. Keep it to one paragraph unless your journal guidelines suggest otherwise.

7. Read it once more against the journal's guidelines before you submit. Editors notice when this section is handled carelessly.

Frequently Asked Questions

Does every academic paper need an acknowledgements section?

Not every journal requires one, but most expect it if contributors or funding sources exist. Many journals, including those published by Elsevier and Springer Nature, explicitly require a funding statement and acknowledgement of non-author contributions in their submission guidelines. If you have nothing to acknowledge, some journals ask you to state that explicitly.

Can you acknowledge an AI tool in a research paper?

Yes, and increasingly, journals require it. If you used a large language model or AI writing tool in preparing your manuscript, you must disclose this in the methods section or acknowledgements. AI tools cannot be listed as authors under current ICMJE and COPE guidance, because they cannot take accountability for the work. Disclose the tool, the version, and how it was used.

How do you acknowledge contributors who are not authors when they prefer anonymity?

If a contributor does not wish to be named, respect that preference. You can acknowledge the contribution without the name by writing something like "the authors thank an anonymous reviewer for feedback on an earlier draft." Always ask permission before naming anyone, and honour their answer either way.

What is the difference between an acknowledgements section and a contributor roles statement?

A contributor roles statement, often formatted using the CRediT taxonomy (Contributor Roles Taxonomy), lists the specific roles each author played in the research, such as conceptualisation, methodology, or writing. It applies to listed authors. The acknowledgements section covers people who are not authors. Some journals require both, so check the guidelines for your target publication.

Should a supervisor always be listed as an author on a student paper?

Only if they meet the ICMJE authorship criteria. A supervisor who gave general oversight or approved the project direction but did not contribute intellectually to the design, analysis, or writing does not automatically qualify. Many supervisors are correctly placed in acknowledgements. Discuss authorship criteria with your supervisor early in the project, not after the paper is written.

Getting This Right Before You Submit

Acknowledgements are a small section of a research paper, but they carry real weight. They show editors that you understand the ethics of attribution. They protect the people who helped you from being misrepresented. They demonstrate that you take publication seriously as a practice, not just as an outcome.

Take the time to do this section properly. Check the specific guidelines for your target journal. Get consent from everyone you name. Be specific about what each person did. And if you are still building your understanding of the full submission process, the Publication Compass blog covers the practical steps of academic publishing for student researchers at every stage.
