Publication in a peer-reviewed journal is one of the key indicators of a scholar's academic activity. It is peer review that provides an independent expert evaluation of a paper prior to publication: without this procedure, most serious journals' editorial teams do not consider submitted materials.
What is a peer review of a scientific article?
Peer review is a written assessment by a specialist in the relevant subject area, evaluating the scientific validity, relevance, and quality of the submitted material. The reviewer analyses the work independently and submits their assessment to the editorial team, which then decides whether to accept the article, return it for revision, or reject it. Peer review is applied in journals indexed in Scopus and Web of Science, as well as in publications included in the HAC list and national academic citation databases.
Why peer review is needed: key functions
Peer review performs several interrelated tasks that maintain the quality of published materials:
- verification of scientific validity – the reviewer checks whether the conclusions are supported by a sound evidential basis and appropriate methodology
- assessment of relevance – whether the topic fits the current academic discourse is determined
- identification of errors – factual, methodological, or logical inaccuracies are established
- confirmation of scientific novelty – whether the work makes an independent contribution to the field of knowledge is assessed
- compliance with the journal's scope – how closely the article's subject matter corresponds to the journal is evaluated
Accordingly, peer review not only filters out weak material, but also helps the author to improve their work prior to publication.
Who writes a peer review of a scientific article?
The reviewer is a scholar with relevant experience and publications in the corresponding field. As a rule, specialists holding an academic degree – Candidate of Sciences or Doctor of Sciences – are engaged. The reviewer must be independent and unaffiliated with the author: co-authorship or a direct conflict of interest constitutes grounds for declining to review. The final selection of the reviewer remains with the editorial team. The reviewer observes confidentiality: the content of the manuscript is not disclosed prior to completion of the procedure.
Criteria for evaluating a scientific article by a reviewer
The content of the review is determined by the requirements of the specific journal; however, in most cases the reviewer assesses:
- Correspondence of the article's subject matter to the journal's scope.
- Relevance of the scientific problem under consideration.
- Methodological soundness of the research conducted.
- Reliability and validity of the data used.
- Logical coherence of the structure and the argumentation in the text.
- Scientific novelty and practical significance of the results.
- Accuracy of the bibliography and compliance with publication ethics requirements.
Following peer review, the editorial team accepts the article, sends it for revision, or rejects it. In the event of a revision, the author receives substantiated comments.
How does peer review affect the publication of a scientific article?
A positive reviewer assessment does not guarantee automatic publication – the final decision is taken by the editorial board, taking into account all submitted evaluations. It is the review that forms the basis for this decision. Where serious methodological shortcomings are identified, the article is sent for revision; in the case of minor comments, the author is asked to make amendments without undergoing a further round of review.
Types of peer review for scientific articles
Depending on the editorial policy, one of the following formats is applied:
- single-blind peer review – the reviewer knows who the author is, whilst remaining anonymous themselves
- double-blind peer review – neither the author nor the reviewer knows who the other party is; the most widely used format in academic circles
- open peer review – both parties are known to each other; in a number of journals, reviews are published alongside the article
The specific format is determined by the journal's editorial policy and the conventions of the discipline.
Peer review is a standard procedure that ensures the reliability and quality of academic publications. Understanding what a reviewer assesses allows an author to prepare their article for submission and reduce the risk of rejection.
