What is an impact factor (and does it matter for student journals)

You have probably heard the term thrown around in conversations about academic publishing. What is an impact factor, and does it matter for student journals? The answer is more nuanced than most guides admit, and understanding it will make you a sharper researcher and a more informed author.

The Basic Definition

An impact factor is a numerical score assigned to an academic journal. It measures how frequently articles published in that journal are cited by other researchers over a defined period, typically two years. A journal with a high impact factor is, in theory, one whose articles are widely read and referenced across the scholarly community.

The metric was developed by Eugene Garfield at the Institute for Scientific Information in the 1960s. It became the dominant proxy for journal prestige in the decades that followed. Today, journals like Nature and The Lancet carry impact factors in the dozens, while most specialized journals sit below five. Many legitimate, rigorous journals have an impact factor of zero, simply because they are too new or too niche to have accumulated citation data.

How Impact Factor Is Calculated

The formula is straightforward. Take the number of citations received in a given year for articles published in the previous two years. Divide that by the total number of citable articles published in those same two years. The result is the impact factor for that year.

For example, if a journal published 100 articles in 2022 and 2023, and those articles received 400 citations in 2024, the journal's 2024 impact factor would be 4.0. Simple arithmetic, but the implications are significant. Journals in fields with large research communities, like molecular biology or oncology, naturally accumulate more citations than journals in philosophy or medieval history. Comparing impact factors across disciplines is therefore misleading (a point many researchers ignore at their peril).

Why Impact Factor Became So Influential

Universities began using impact factor as a shorthand for evaluating faculty productivity. Grant committees leaned on it. Tenure decisions referenced it. When researchers needed a fast, defensible way to rank journals, impact factor filled the gap. It is a blunt instrument that became institutionalized because it is measurable, not necessarily because it is accurate.

The metric has significant critics. It can be gamed through self-citation practices. Review articles, which summarize existing literature, accumulate citations far faster than original empirical work, inflating the scores of journals that publish them heavily. The San Francisco Declaration on Research Assessment (DORA), signed by thousands of researchers and institutions worldwide, explicitly warns against using impact factor to evaluate individual research contributions. The metric measures journal-level performance, not paper-level quality.

What Is an Impact Factor for Student Journals Specifically?

Here is where the conversation shifts. When high school researchers ask what is an impact factor for student journals, the honest answer is: it is largely irrelevant, and here is why that is not a problem.

Impact factor scores are calculated and maintained by Clarivate Analytics through the Journal Citation Reports (JCR). To receive an official impact factor, a journal must first be indexed in the Web of Science Core Collection. That indexing process takes years. A journal must demonstrate sustained publication history, editorial rigor, and citation activity before Clarivate considers it. Most student research journals, regardless of their quality, have not existed long enough to meet those criteria.

This does not mean student journals are not legitimate. It means they are operating in a different part of the publishing ecosystem, one that does not require an impact factor to deliver real value to student researchers. Understanding what it means for a journal to be indexed in Google Scholar or EBSCO is a more relevant question for student authors evaluating where to submit their work.

What Actually Matters for Student Research Publications

If impact factor is not the right metric for student journals, what should you be evaluating? Several factors carry genuine weight.

Peer Review Integrity

A rigorous peer review process is the most important indicator of a journal's legitimacy. Blind review, conducted by qualified reviewers who evaluate your work on its merits alone, is the standard that separates credible publications from vanity presses. Understanding what peer review actually verifies and what it does not will help you ask the right questions before you submit.

Indexing and Discoverability

A published paper that no one can find delivers limited value. Journals indexed in Google Scholar, EBSCO, or similar databases ensure your work is discoverable by researchers, educators, and future collaborators. Discoverability is a practical measure of reach, and it matters far more for student authors than an impact factor score that the journal cannot yet possess.

DOI Assignment

A Digital Object Identifier (DOI) is a permanent, unique link assigned to your published paper. It makes your work citable in a standardized format and ensures it remains findable even if a journal's website changes. A DOI signals that a journal takes the permanence of its publications seriously (it exists forever, findable by anyone). Any credible journal publishing original research should assign a DOI to every paper.

Editorial Feedback Quality

For student researchers, the review process is not just a gatekeeping mechanism. It is a formative experience. Journals that provide substantive, constructive feedback help you grow as a researcher. Journals that return a one-line acceptance or rejection without explanation offer little developmental value. The quality of feedback you receive is a direct indicator of how seriously a journal takes its educational mission.

Submission Transparency

Legitimate journals are clear about their timelines, review processes, and editorial standards. Understanding what rolling admission means for journal submissions helps you plan your submission strategy and set realistic expectations about publication timing.

The Danger of Impact Factor Obsession at the Pre-Collegiate Level

Some students, and occasionally their advisors, make the mistake of dismissing student journals entirely because they lack an impact factor. This reasoning is flawed. It applies a metric designed for professional academic journals to a category of publication that serves a fundamentally different purpose.

Student journals exist to give emerging researchers a credible, rigorous venue for original work produced before they enter undergraduate or graduate programs. The value of publishing in a strong student journal is not measured in citations per year. It is measured in the quality of the review process you experienced, the permanence of your published contribution, and the skills you developed in preparing your manuscript for external evaluation.

A high school student who completes a rigorous submission process, responds to peer reviewer comments, and publishes original research in a credible, indexed journal has demonstrated something meaningful. That is a verifiable scholarly contribution, regardless of whether the journal carries a Clarivate impact factor.

How to Evaluate a Student Journal Without an Impact Factor

Ask these questions before you submit your work anywhere.

• Is the peer review process blind? Reviewers should not know your name, school, or country. Blind review is the only way to ensure your work is evaluated on merit alone.

• Does the journal assign DOIs? Permanent identifiers are non-negotiable for work you want to remain citable.

• Is the journal indexed? Google Scholar indexing is a baseline. EBSCO or similar database inclusion adds further credibility.

• Is the journal open access? Open access publishing ensures your work reaches the widest possible audience without paywalls blocking access.

• Does the journal publish across disciplines? Journals that accept work across STEM, humanities, social sciences, and interdisciplinary fields tend to have broader reach and more diverse editorial expertise.

• What does the editorial feedback look like? Ask to see examples of reviewer comments or talk to students who have published there. Substantive feedback signals a journal that takes research development seriously.

What This Means for Your Research Journey

If you are conducting original research as a high school student, whether a controlled experiment, a qualitative study, a meta-analysis, or a theoretical analysis, your primary goal is to produce work that meets a genuine scholarly standard. The publication venue matters, but the right standard to apply is not impact factor. It is rigor, transparency, and discoverability.

The question of what is an impact factor for student journals ultimately resolves into a more useful question: is this journal credible, is the review process legitimate, and will my published work be permanently accessible and findable? Those three criteria will serve you better than chasing a metric that does not yet apply to the pre-collegiate publishing space.

If you are exploring different study designs for your research, resources on what a longitudinal study is and whether a student can run one or what a meta-analysis involves for high school students can help you match your methodology to your research question before you reach the submission stage.

Academic integrity is equally non-negotiable. Understanding what counts as academic dishonesty in student research ensures that the work you submit reflects your genuine contribution and meets the ethical standards that any credible journal will enforce.

The Bottom Line

What is an impact factor, and does it matter for student journals? It is a citation-based metric developed for professional academic journals, and for pre-collegiate publications, it is not the right lens. Impact factor measures something real in the professional publishing world, but it is a poor proxy for quality even there, and it is entirely inapplicable to journals that have not yet accumulated the publication history required for the metric to exist.

What matters for student researchers is whether the journal conducts rigorous blind peer review, assigns DOIs, maintains indexing for discoverability, and delivers substantive feedback that makes you a better scholar. Those are the standards that exceptional student research deserves, and they are the standards worth holding any publication venue to.
