Quartile (Q) is one of the main indicators in the world of academic research. It evaluates the quality of a scientific publication based on citation metrics. Ranking by quartile is carried out with the determination of four categories: Q1, Q2, Q3, Q4. Such an approach is used by the most authoritative databases, including Scopus and Web of Science.

What does Q1, Q2, Q3, Q4 mean in journals?
To determine the quartile (Q) of a journal, its impact factor or CiteScore is used, which reflects how many times articles from that journal have been cited in other scientific publications over a certain period of time. The classification of journals by quartile (Q) is based on the impact factor.
- Q1 includes the most prestigious journals in the field with the highest number of citations.
- Q2 covers journals with slightly lower impact factors, but still of high quality.
- Q3 are fairly ranking and influential publications that are suitable for achieving almost all scientific goals.
- Q4 includes journals with lower impact factors, often those that have recently been included in the database.
The quartile (Q) of a journal can be found by viewing its impact factor and number of citations on the journal's official website or in databases such as Web of Science or Scopus. Some researchers and scholars also compile their own journal rankings, which can help determine the quartile of a journal. However, the most up-to-date information is still posted in bibliographic databases.

How to determine if a journal is in Q1?
To determine if a journal is in Q1, you need to check its impact factor or CiteScore. The impact factor reflects how many times articles from the journal have been cited in other scientific publications over a certain period of time. A journal's Q1 is determined by its impact factor. To be classified as Q1, a journal's impact factor must be in the highest quartile (the top 25%) among journals publishing in the same field of science. In other words, if the impact factor of a journal is in the top quartile based on its value, then the journal is in Q1. The impact factor of a Q1 journal is typically very high. To determine if a journal is in Q1, you need to check its impact factor in bibliographic databases such as Web of Science or Scopus.
How to determine Q1 or Q2?
To determine if a journal is in Q1 or Q2, you need to check its impact factor or CiteScore.
- To be classified as Q1, a journal's impact factor must be in the highest quartile (the top 25%) among journals publishing in the same field of science.
- To be classified as Q2, a journal's impact factor must be in the upper half (the top 50%) of journals publishing in the same field of science.
To determine whether a journal belongs to the Q1 or Q2 category, you need to check its impact factor in bibliographic databases such as Web of Science or Scopus.
Is it worth publishing in Q3 or Q4 journals?
Publishing in journals included in Q3 or Q4 may have its advantages:
- Such journals are more accessible to authors in terms of pricing policy.
- They are perfect for publishing their first works.
- They may be more specialized and relevant.
- They are suitable for achieving basic scientific goals.
If you want to publish in Q3 or Q4 journals, it is important to assess which journals are most suitable for your work and which journals are most suitable for your target audience. It is also important to ensure that the journal has a good reputation in your field and is not predatory, trying to make money from publications without real peer review.
Finally, it should be noted that publishing in a Q3 or Q4 journal does not necessarily mean that your work is not valuable or will go unnoticed. If your work contains new and important results, it can attract attention even from less prestigious journals and become a starting point for future research and publications.
