Preparing a scientific article for publication consists of a number of important stages, including peer review. It helps to objectively assess the research and influences the editorial decision regarding the acceptance of the work by a journal. In our article, we will consider the key features of peer review and the main stages of this process.

Types of peer review
Peer review – is a process of independent evaluation during which experts assess a scientific article for quality, relevance and compliance with the requirements of the publication. It is usually of the following types:
- Single-blind peer review – is one of the most common peer-review formats, which provides anonymity only for reviewers. Information about the author is open to independent experts in this case.
- Double-blind peer review – is usually used to ensure greater objectivity during the evaluation. Its distinctive feature is that authors and reviewers do not know each other’s names.
- Open peer review – is a format in which the names of authors and reviewers are not concealed.
- Transparent peer review – is a type that involves making the materials of the peer-review process available, including reviewers’ comments, authors’ responses, editorial decisions or the history of manuscript revisions. The scope of the information made available depends on the policy of a particular journal.
- Collaborative review – is a format that involves interaction between reviewers, the editorial office and, in certain cases, authors during the evaluation of a manuscript. This enables participants in the process to discuss controversial points in a scientific article and work on its improvement.
- Post-publication review – is a type of evaluation of a scientific article that takes place after its publication or open dissemination.
How does the peer-review process take place?
1. Submission of an article to a journal
The author must submit their article to the editorial office of the publication. Before doing so, it is necessary to familiarise oneself with the requirements and to check whether the work corresponds to the journal’s scope.
After that, the editorial office conducts an initial screening. If the article has serious shortcomings, it may not be allowed to proceed to external peer review.
2. Appointment of reviewers for expert evaluation of the article
If the article passes the initial screening, the journal editor selects several independent experts who have specialist knowledge in the relevant field. During the evaluation, reviewers must adhere to objectivity, constructiveness and impartiality.
They mainly pay attention to:
- relevance of the topic
- novelty of the research
- correctness of the methodology
- reliability of the results
- logic of the conclusions
- correctness of the formatting of sources
Compliance with the principles of academic integrity is also taken into account. The work must be original, contain appropriate citations, transparent data and well-founded conclusions.
3. Editorial decision
After receiving detailed reviews and recommendations from the reviewers, the editorial office must make a decision regarding the article. The following options are usually possible:
- acceptance – means that the article meets all requirements and is ready for publication
- request for revision – means that the author needs to make certain amendments to their work
- rejection of the work – means that the manuscript has significant shortcomings and does not meet the journal’s standards
Peer review is an important stage for a researcher, as it usually makes it possible to assess the strengths and weaknesses of a scientific article before its publication. The key advantage of this process is receiving an independent expert evaluation, which makes it possible to revise the work and improve its quality.
