How to write an author contribution statement for a research paper | RISE Research

TL;DR: An author contribution statement is a short, required section in most peer-reviewed journals that explains exactly what each named author did on a research project. Many high school researchers get flagged at submission or rejected outright because they omit this section or write it incorrectly. This post explains what to include, how to format it, and why it matters more than most students expect. If you need guidance on this at the submission stage, book a free Research Assessment with RISE.

The section most high school researchers forget until it is too late

Most guides on how to write an author contribution statement for a research paper are written for university students submitting to discipline-specific journals with established co-author teams. High school researchers face a different situation. They are often sole authors, sometimes working with a mentor, and rarely told that journals require this section at all. The result is a submission that stalls at the editorial desk before a single reviewer reads the actual research.

Author contribution statements are now mandatory at most indexed, peer-reviewed journals. Nature, PLOS ONE, Frontiers, and the majority of journals using the ICMJE guidelines all require one. Submitting without one is not a minor formatting error. It is a reason for desk rejection. This post covers exactly how to write an author contribution statement for a research paper, what journals expect, and how to handle the specific situations high school researchers encounter most often.

What is an author contribution statement in a research paper?

Answer Capsule: An author contribution statement is a brief section, typically 50 to 150 words, that lists each author by name and describes their specific role in the research. It is required by most peer-reviewed journals and is used to ensure transparency about who did what. It is separate from the acknowledgements section.

The author contribution statement exists because academic publishing has a transparency problem. For decades, papers listed authors without explaining their individual roles. Senior researchers sometimes appeared on papers they barely contributed to. Junior researchers sometimes did most of the work without credit. The author contribution statement was introduced to fix this.

Most journals now use a framework called the CRediT taxonomy (Contributor Roles Taxonomy), developed by NISO. CRediT defines 14 specific contributor roles: Conceptualization, Data Curation, Formal Analysis, Funding Acquisition, Investigation, Methodology, Project Administration, Resources, Software, Supervision, Validation, Visualization, Writing (Original Draft), and Writing (Review and Editing). Journals ask authors to assign one or more of these roles to each contributor listed on the paper.

For a high school student submitting a paper, this section serves an additional function. It clarifies the relationship between the student researcher and any mentor, supervisor, or faculty co-author. Getting this right protects the student's academic integrity and satisfies the journal's editorial requirements. Getting it wrong, or skipping it, signals inexperience to editors who review hundreds of submissions.

How to write an author contribution statement for a research paper: the full process

Step 1: Identify every contributor and their actual role

Before you write a single word of the statement, list every person who contributed to the research. This includes yourself, any co-authors, your research mentor, and anyone who provided data, laboratory access, or significant analytical support. Do not list everyone who helped. The author contribution statement covers named authors only. Broader acknowledgements go in the separate acknowledgements section.

For each named author, write down what they actually did using the CRediT categories. Be honest. If your mentor reviewed and edited your draft but did not design the study, that is Writing (Review and Editing), not Conceptualization. Overstating a contributor's role is a form of academic misrepresentation. Understating your own role as the primary researcher is also a mistake, and one that matters for your college application.

Step 2: Check the target journal's specific format requirements

Every journal has its own author guidelines. Some journals require CRediT role labels in parentheses after each name. Others ask for a free-text paragraph. Some require both. Before you write the statement, go to the journal's official author instructions page and find the exact format they require. This step is non-negotiable. A statement written in the wrong format for that journal will need to be rewritten at submission, which delays the process and creates unnecessary back-and-forth with the editorial office.

Journals like PLOS ONE publish their author contribution requirements directly in their submission guidelines. Frontiers journals use the CRediT taxonomy and require it in a structured format. Check the specific page for the journal you are targeting, not a general summary of what journals require.

Step 3: Write the statement in the correct format

A correctly formatted author contribution statement for a high school researcher working with a mentor typically looks like this:

Author Contributions: [Student Name]: Conceptualization, Methodology, Investigation, Formal Analysis, Writing (Original Draft), Visualization. [Mentor Name]: Supervision, Writing (Review and Editing).

If the journal requires a free-text paragraph rather than the CRediT format, write one sentence per author. Keep it specific. Avoid vague phrases like "contributed to the research." Name the actual tasks. Here is a correctly written free-text version:

[Student Name] designed the study, collected and analysed all data, and wrote the original manuscript. [Mentor Name] provided supervisory guidance throughout the project and reviewed and edited the final manuscript. All authors read and approved the final version.

The final sentence confirming all authors approved the manuscript is required by most journals. Include it regardless of whether the journal explicitly asks for it.

Step 4: Confirm authorship criteria are met for every named author

Most journals follow the ICMJE authorship criteria, which require that every named author meets all four of these conditions: substantial contribution to conception or design, or to data acquisition, analysis, or interpretation; drafting or critically revising the work; final approval of the version to be published; and agreement to be accountable for all aspects of the work. A person who only provided data or only edited one section does not meet the ICMJE threshold for authorship. They belong in the acknowledgements section instead. Listing someone as an author when they do not meet these criteria is called gift authorship, and it is a serious ethical violation that journals actively screen for.

How does an author contribution statement affect your college application?

Answer Capsule: The author contribution statement directly affects how admissions officers interpret a published paper. A statement that shows the student as the primary investigator and author carries significantly more weight than one where the student's role is ambiguous or secondary. Admissions offices at selective universities are increasingly familiar with academic publishing norms.

When a published paper appears in a college application, it does not stand alone. Admissions officers at research-focused universities look at the full submission record, including the author contribution statement, to assess the student's genuine intellectual contribution. A paper where the student is listed first and the contribution statement confirms they led the conceptualization, investigation, and writing is a materially stronger credential than a paper where the student's role is listed as data collection only.

RISE scholars achieve a 90% publication rate across more than 40 peer-reviewed journals, and a core part of that outcome is submitting papers where the student's authorship is clearly and accurately documented. RISE scholars accepted to Stanford at 18% compared to the standard 8.7% rate, and to UPenn at 32% compared to the standard 3.8% rate. A well-documented publication record, including a correctly written author contribution statement, is part of what makes that difference visible to admissions committees.

On the Common App, a published paper is listed under the Additional Information section or as an honor. The author contribution statement is part of the paper itself, so when admissions officers access the publication, they see it directly. This is why accuracy matters as much as completion.

Where students working alone get stuck with author contribution statements

The first sticking point is not knowing the section exists until after the paper is written. Most high school research guides, including general guides on how to write a high school research paper, do not cover submission requirements in detail. Students spend months on the research and the writing, then discover at submission that they need additional sections they have never seen before. The author contribution statement is one of the most commonly missed.

The second sticking point is correctly categorising a mentor's role. Students often either over-attribute contributions to their mentor out of gratitude, or under-attribute them to make the paper look more independently produced. Both create problems. Over-attribution can raise questions about the student's actual contribution. Under-attribution can misrepresent the mentor's role in ways that violate journal ethics policies. Getting this balance right requires understanding both the CRediT taxonomy and the specific journal's expectations.

The third sticking point is navigating journals that use non-standard formats. Some journals, particularly those that explicitly welcome high school submissions, have simplified their author guidelines. Others use the full ICMJE and CRediT framework without modification. A student submitting for the first time has no reference point for what a correctly formatted statement looks like in context.

A research mentor who has published in their own field has written dozens of author contribution statements. They know which journals require CRediT labels, which prefer free text, and how to accurately represent a student's role in language that satisfies editorial requirements without misrepresenting the work. RISE mentors, drawn from 500+ PhD-level researchers published across 40+ journals, provide this guidance at every stage of the publication process.

Frequently asked questions about author contribution statements

Do I need an author contribution statement if I am the only author on the paper?

Yes. Most peer-reviewed journals require an author contribution statement even for sole-author submissions. In this case, the statement simply confirms that the single author performed all roles. A typical sole-author statement reads: "[Name]: Conceptualization, Methodology, Investigation, Formal Analysis, Writing (Original Draft and Editing)." Check your target journal's guidelines to confirm the exact format required.

Should my research mentor be listed as a co-author or in the acknowledgements?

This depends on what your mentor actually did. If your mentor meets all four ICMJE authorship criteria, including contributing to conception or analysis, revising the manuscript, approving the final version, and agreeing to be accountable for the work, they qualify as a co-author. If they provided guidance, feedback, or supervision without meeting all four criteria, they belong in the acknowledgements section. Listing a mentor as a co-author when they do not meet the criteria is gift authorship, which violates journal ethics policies.

What is the CRediT taxonomy and do all journals use it?

CRediT (Contributor Roles Taxonomy) is a standardised framework of 14 contributor roles developed by NISO to bring consistency to author contribution statements. Major publishers including Elsevier, Springer Nature, PLOS, and Frontiers use it. Not all journals require it. Some journals, particularly smaller independent journals that accept high school submissions, use free-text formats instead. Always check the specific journal's author guidelines before writing your statement.

Can I write my author contribution statement before the paper is finished?

You can draft it early, but finalise it only after the paper is complete. Contributions sometimes shift during the research process. A co-author who was expected to contribute to data analysis may end up contributing primarily to writing. The statement must reflect what actually happened, not what was planned. Writing a draft early is a useful way to clarify roles with co-authors before submission, but treat it as provisional until the manuscript is finalised.

Where does the author contribution statement appear in a research paper?

The author contribution statement typically appears at the end of the paper, after the discussion or conclusion and before the references. It is a separate section from the acknowledgements. Some journals place it on the title page instead. Check your target journal's manuscript formatting guidelines, which are usually found in the "Instructions for Authors" section of the journal's official website, to confirm the correct placement for that specific publication.

What to take from this post

The author contribution statement is not a formality. It is a required section that protects your academic integrity, satisfies journal editorial requirements, and signals to admissions officers exactly how much of the research was yours. Most high school researchers encounter it for the first time at the submission stage, which is too late to navigate it without stress. Understanding the CRediT taxonomy, knowing how to represent a mentor's role accurately, and matching the format to the specific journal's requirements are all skills that take time to develop. For guidance on the broader submission process, the RISE publications page outlines how RISE scholars approach journal selection and submission across disciplines. You may also find it useful to read about how to write a research abstract in high school and how to write a strong research paper conclusion, both of which are sections that need to be in strong shape before submission.
