What’s The Difference Between Q1, Q2, Q3, And Q4 Journals?

Q1, Q2, Q3, and Q4 journals are journal ranking categories that show where a journal stands within its subject area. In simple words, Q1 journals are usually placed in the top 25% of journals in a specific field, Q2 journals fall in the next 25%, Q3 journals fall in the third group, and Q4 journals are placed in the lowest 25% of that category.

For postgraduate, MPhil, and PhD scholars, these quartiles matter because supervisors, universities, funding bodies, and promotion committees often use journal quartile rankings to judge the academic strength of a publication. A Q1 or Q2 publication is usually considered stronger because the journal has higher visibility, stronger citation performance, and greater academic recognition within its discipline. However, this does not mean every Q3 or Q4 journal is useless. A lower-quartile journal may still be suitable if it is indexed, peer-reviewed, relevant to the research topic, and accepted by the scholar’s university or research body.

The main problem students face is confusion between journal indexing, impact factor, quartile ranking, Scopus status, Web of Science status, and predatory journal risk. A proper journal selection decision should not be based only on the quartile label. It should consider the journal’s subject scope, indexing database, publication ethics, review process, acceptance difficulty, article processing charges, and institutional requirements.

What exactly do you get from this guide?

This guide explains how Q1, Q2, Q3, and Q4 journals differ, how journal quartiles are calculated, and how researchers can select the right journal for thesis publication, research paper submission, academic promotion, or PhD requirements. It is written for scholars who want to avoid random journal selection and make a supervisor-ready publication decision.

You will learn:

• What Q1 journals mean: How top-quartile journals are usually linked with stronger citation performance, higher academic visibility, and more competitive peer review.
• What Q2 journals mean: Why Q2 journals are often a practical option for scholars who need strong indexing but may not be ready for the highest rejection rates of Q1 journals.
• What Q3 journals mean: How Q3 journals may still be acceptable when the journal is indexed, relevant, ethical, and aligned with university requirements.
• What Q4 journals mean: Why Q4 journals require careful checking because some may be valid but others may have weaker academic influence or limited recognition.
• How quartiles are checked: Why scholars should verify quartile status through trusted indexing sources such as Scopus-based journal metrics, SCImago Journal Rank, or Web of Science Journal Citation Reports where applicable.
• How to avoid wrong journal selection: Why researchers must check journal scope, indexing status, publication ethics, review timeline, APC charges, and supervisor approval before submission.
• How to match the journal with your research level: Why a PhD scholar, MPhil student, or early-career researcher may need different journal strategies depending on institutional expectations and publication goals.

Why should you trust this approach?

Understanding Q1, Q2, Q3, and Q4 journals is important because journal selection directly affects research visibility, supervisor approval, publication credibility, and academic career planning. Many scholars make the mistake of choosing a journal only because it claims to be “international” or “indexed,” without verifying whether it is actually recognized in their field.

A reliable journal selection approach must combine ranking awareness with academic judgment. Quartile ranking is useful, but it should not replace proper evaluation of journal relevance, indexing database, peer-review quality, publication ethics, and university guidelines. This is especially important for PhD and MPhil scholars because a wrong journal choice can waste months of effort, delay thesis completion, or create problems during supervisor review.

The safest approach is to treat journal quartiles as one part of the decision, not the whole decision. A strong publication strategy should match the scholar’s topic, methodology, academic level, target audience, institutional criteria, and realistic publication timeline.

The classification of journal quality within a specific field is determined through a quartile ranking system, which categorizes journals into four tiers: Q1, Q2, Q3, and Q4. These rankings are based on impact factors and citation metrics, which serve as key indicators of a journal’s influence and reach within the academic community. The implementation of this quartile system traces its origins to the Journal Citation Reports (JCR), introduced by the Institute for Scientific Information (ISI) in 1975. Initially designed to evaluate and rank scientific periodicals, the system was later expanded to encompass journals across a broader spectrum of disciplines, including the social sciences and beyond.

The main idea of the JCR and the quartile ranking system was the idea to have a common way of evaluating the impact and prestige of scholarly journals. Journals in the natural sciences were the major subject of its concern at its inception, signaling the increased emphasis on scientific research, and communication of the same. In the course of time the system shifted to incorporate journals representing a wide range of disciplines thus presenting an effective tool of assessing the scholarly output of various disciplines.

The quartile ranking system is now considered one of the most important criteria measures of researchers, institutions and funders. Q1 journals are the leading 25 percent journals published in a subject or field, which are considered most desired because of the high impact factors and critical spill over of the journals. Such journals tend to be connected with ground-breaking studies, and they are thought to be the gold standard of scholarly journal publishing.

In the meantime, Q2, Q3 and Q4 journals are also important constituents of the academic ecosystem, which offer opportunities to disseminate the results of such specialized research, new areas of research, and early-career researchers to demonstrate their findings.

The quartile system not only aids in the evaluation of journal quality but also serves as a strategic tool for researchers aiming to maximize the visibility and impact of their work. By targeting journals within specific quartiles, researchers can align their publications with the expectations of their field, enhance their academic profiles, and contribute to the advancement of knowledge in meaningful ways.

To conclude, the quartile ranking system, which is based on the pioneer by the JCR and ISI, is a necessary element of the academic environment. It offers a disciplined interface of evaluating journal quality, excellence in research, and advocating spread of knowledge in multiple fields.

These are quartile rankings assigned to academic journals based on their impact factor or citation metrics. They are used to categorize journals within specific subject areas:

• Q1 Journals: The most prominent, considered among top 25 percent of the journals in the field. 
• Q2 Journals: Has the second quarter, still quite reputable: 
• Q3 Journals: The central 50 percent, has a reputation but not much impact on the sector. 
• Q4 Journals: The least, below the average and the last 25 percent of the journals, are often weak influence in their fields.

Q1, Q2, Q3, and Q4 Journals Compared

Q1, Q2, Q3, and Q4 represent four quartile groups used to indicate a journal’s relative position within a particular subject category and ranking database. Q1 journals occupy the highest 25 percent, while Q2 journals generally fall between the twenty-fifth and fiftieth percentiles within their assigned category. Q3 journals occupy the third quartile, whereas Q4 journals appear within the lowest 25 percent according to the selected ranking system. However, these classifications may differ across JCR, CiteScore, and SCImago because each system uses different citation data, calculations, subject categories, and reporting periods.

Journal Quartile	Approximate Position	General Meaning	Publication Competition	Suitable Research Profile
Q1	Top 25%	Highest-ranked journals within a subject category	Usually very high	Original research with strong methodology, clear contribution, and broad academic relevance
Q2	25% to 50%	Strong second-quartile journals within their category	High	Sound research with clear contribution, appropriate analysis, and good journal-scope alignment
Q3	50% to 75%	Moderate-ranked journals within their category	Moderate	Specialised, regional, applied, or developing research with acceptable methodological quality
Q4	75% to 100%	Lower-ranked journals within their category	Varies considerably	Niche, regional, early-stage, or narrowly focused research meeting legitimate journal requirements

Why Do Journal Quartiles Matter for Researchers?

Journal quartiles help researchers compare journals within a subject category and identify publication outlets that match their academic goals, institutional requirements, and intended readership. Universities, funding bodies, and promotion committees may consider journal rankings when assessing research output, although their requirements differ across institutions and disciplines. Q1 and Q2 journals generally provide greater citation visibility and wider academic reach, while legitimate Q3 and Q4 journals may suit specialised or regional research. Researchers should therefore consider quartile ranking alongside journal scope, current indexing status, peer-review standards, publication charges, and acceptance under their university’s policy.

• Research Quality: It is often the case that Q1 and Q2 journals are of high quality because they are subject to peer review.
• Citation Impact: This can be advantageous for an author owing to his enhanced research visibility.
• Academic Reputation: This helps to improve researchifying author’s reputation.
• Career Advancement: It may be helpful in securing job promotions and tenure.
• Funding Opportunities: A number of funding bodies have their bias towards researches published in journals of impact factor.

Does a Higher Journal Quartile Mean Better Research?

Research quality is assessed through the originality of the study, appropriateness of its methodology, reliability of the data, ethical compliance, and clarity of the conclusions. A journal’s quartile indicates its relative citation position within a subject category, but it cannot confirm the quality or reliability of every published article. Researchers should therefore evaluate individual studies according to their design and evidence rather than treating journal ranking as the only measure of quality.

• Originality: New ideas and improvements.
• Rigor: Proper methodology and data checking.
• Impact: Major effects for a sector.
• Citation Count: The number of references to a single piece of research work.
• Peer Review Process: Read and screened by competent people.

What Do Q1 and Q2 Journals Usually Expect from a Manuscript?

Q1 and Q2 journals generally expect manuscripts to present an original research problem, appropriate methodology, reliable evidence, ethical compliance, and a clearly explained scholarly contribution. Authors must also follow the journal’s scope, article structure, referencing style, reporting standards, and instructions for presenting tables, figures, data, and supplementary materials. These expectations vary across disciplines and journals, so researchers should examine the target journal’s recent publications and author guidelines before preparing their submission.

• Original Research: Creation of new ways of thinking.
• Strong Methodology: Research design and data evaluation are adequately met.
• Clear Writing: Content is organized logically for ease of comprehension.
• Significant Impact: Advancement of knowledge and possible ways of applying it in practice.
• Adherence to Ethical Guidelines: Ethical behavior and adherence to the rules.
• High-Quality Figures and Tables: Graphics that help comprehension.
• Comprehensive Literature Review: Appropriate researches are all discussed.
• Robust Discussion: Reasonable interpretation of the findings and their consequences

Can a Journal’s Quartile Change Over Time? 

A journal’s quartile may change between reporting years because citation performance, database coverage, subject classifications, and the rankings of competing journals can change. The same journal may also receive different quartiles across subject categories or ranking systems, including Journal Citation Reports, CiteScore, and SCImago SJR. Researchers should therefore verify the journal’s current quartile, indexing status, subject category, and reporting year near submission rather than relying on older lists.

• Journal Rankings: Journal rankings can change over the years. A journal which was ranked Q1 last time, may be ranked Q2 or Q3 the succeeding time.
• Impact Factor: A crucial factor employed for determining how much influence a journal has. Universally, the higher the impact factor the more reputable the journal.
• Peer Review Process: The cream of the crop journals possess a wider range of peer-review processes which include several rounds of review and constructive criticism.
• Submission Guidelines: Q1 and Q2 journals generally have a great degree of submission guidelines, for instance, formatting and word count requirements.
• Acceptance Rates: These kinds of journals usually have fewer acceptance rates which tends to make publishing in them more competitive.
• For the most reliable and current access of ranking information, impact factors, and submission information:-
• Scopus: This is a rich source for literature that has been peer reviewed.
• Web of Science: Yet, another foremost official database for scientific information and academic research.
• Journal web pages: View the requirements and particulars of your chosen journal on its website, especially its submission guidelines, peer review process and the impact factor.

These kinds of factors you need to keep in your mind and the best research and writing guidelines which will enable you to publish in the journals of high standard..

How Do Journal Editors Evaluate Manuscripts Submitted to Ranked Journals?

Journal editors initially examine whether a manuscript matches the journal’s scope, article type, readership, submission requirements, and expected level of scholarly contribution. They also consider originality, methodological suitability, ethical compliance, data presentation, academic writing quality, and the relevance of findings before initiating external peer review. A journal’s Q1, Q2, Q3, or Q4 status does not replace this evaluation because editors assess each submission according to their publication standards.

Among the many criteria employed by journal editors to assess the quality and impact of received submissions include the Q1, Q2, Q3, and Q 4 journal categories. Here is how they do it:

Key Criteria Used During Editorial Screening

Editors examine whether the manuscript fits the journal’s scope, addresses a relevant research problem, and offers an identifiable contribution to its intended readership. They also assess methodological suitability, ethical compliance, data transparency, writing quality, article organisation, and adherence to the journal’s submission instructions. Manuscripts failing these preliminary checks may receive a desk rejection before external reviewers examine their arguments, methods, findings, or scholarly contribution.

• Impact Factor: The editors consider the impact factor of the journal i.e. the measures of how frequently the average article of the journal has been cited. Q1 journals on the contrary will always be of higher impact factor meaning that they will be more visible and prominent.
• Citation Metrics: This is a record of the frequency of a journal. The number of citations to a journal is a significant measure of the rank in equivalence. While, Q1 journals are cited more than Q2, Q3, and Q4 journals.
• Peer Review Quality: The peer review can also be a key part that should be well and sound. Greater surveillance exists on the process of peer review that regulates quality of research in Q1 journals.
• Research Relevance: Needless to say, the topicality of researches to a certain region and their significance is an accent. Q1 journals mainly publish original and intentional pieces of research.

How Are Q1, Q2, Q3, and Q4 Journal Quartiles Calculated?

Journal quartiles are generally calculated by ranking journals within a defined subject category according to citation-based indicators used by the selected ranking system. The ranked journals are then divided into four approximate groups, with Q1 representing the highest-ranked 25 percent and Q4 representing the lowest-ranked 25 percent. JCR, CiteScore, and SCImago use different datasets and calculation methods, so one journal may receive different quartiles across databases, categories, or reporting years.

Regarding the journal norms of each specific category (Q1, Q2, Q3, Q4), this can usually include a metric comprised of quartiles in the rankings in which journals are positioned according to their impact factors and so forth.

• Q1 (Top Quartile): Journals in this category have the highest impact factors and are regarded as most reputable and of utmost influence in their area of specialization.
• Q2: This category comprises journals that are still important, but to a lesser degree than those in Q1, since their impact factors are low when compared with those of Q1 journals.
• Q3: These journals are recognized as having moderate impact factors and impact in the area.
• Q4: With respect to other quartile journals, journals in this group have the lowest impact factors and are considered to have less influence.

What Do Q1 and Q2 Journals Usually Expect from a Manuscript?

Q1 and Q2 journals generally expect manuscripts to address a clearly defined research problem and make a meaningful contribution within the journal’s disciplinary scope. Although expectations differ across fields, editors usually examine originality, methodological suitability, ethical compliance, data quality, writing clarity, and alignment with author instructions.

• High Impact Factor: Many citations relative to the number of published articles.
• Rigorous Peer Review: The research undergoes a rigorous and effective peer review process to guarantee quality and correctness.
• Reputation and Prestige: Substantial reputation in the academic circles, many submissions and reputable authors.

Relevance and Novelty 

A manuscript should address a question relevant to the journal’s readership and explain how the study extends, challenges, or applies existing academic knowledge. Novelty does not always require a completely new theory because original evidence, methodology, interpretation, context, or practical application may provide a valuable contribution

• Relevance to the Audience: The most relevant focus of the journal paper must be a publication of an important field of research.
• Novelty: The expectation is based on the fact that research should address new, unpublished insights, theories, or data.

Research Design and Data Quality

The research design should match the study objectives, research questions, theoretical framework, data type, and accepted methodological practices within the relevant discipline. Authors should explain their sample, instruments, procedures, analytical methods, validity measures, and limitations clearly enough for reviewers to assess the study’s reliability. Where applicable, the manuscript should provide sufficient information about datasets, experimental conditions, statistical assumptions, coding procedures, or qualitative interpretation methods.

​Iterative Nature of Resources

• Research Design: Use of the detailed structured research design that is relevant to the aims of the study.
• Data Quality: Use of reliable and valid data collection tools and analysis techniques.
• Ethical Standards: Ethical codes in relation to the research goals in the undertaking of the research and presentation of report.

Clarity and Organization

Clear academic writing allows editors and reviewers to understand the research problem, methodological choices, findings, and contribution without unnecessary repetition or ambiguous terminology. Each section should follow a logical sequence, while the abstract, introduction, methodology, results, discussion, and conclusion should remain consistent with one another.

• Clear Writing: The written paper must be well prepared including well-expressed and reduced language to the editor’s requirements.
• Logical Flow: An ordered framework of the paper that responds logically to the presented concepts.
• Effective Communication: The capability to relay intricate ideas and results in a manner that is understood by readers.

Ethical Compliance and Transparent Reporting

Authors must report ethical approval, informed consent, funding sources, competing interests, authorship contributions, and data availability whenever these declarations apply to their research. Medical, experimental, and observational studies should follow appropriate reporting guidelines, while all manuscripts must present data honestly and avoid fabrication, manipulation, plagiarism, or misleading interpretation.

• Impact Factor: The likelihood of the research attracting a lot of citations and being in the top rank of the research field.
• Generalizability: The degree of the findings that could be extrapolated to other areas or other people.
• Practical Implications: Aspects and relevance of the research work in practice for the sector or industry.

Case of Q1 Journals-

• Higher Impact: It is in the criterion of Q1 journals where work is selected which has the potential of high citation and is of wide impact.
• Groundbreaking Research: Research that breaks the rules or contributes fresh insights that improve the existing turbulence.
• Stringent Review Process: Having more strict quality checks that are peer reviewed so as to accept paper writing of the highest quality.
• Interdisciplinary Relevance: Papers that have an impact in several disciplines or areas of work.

Tables, Figures, and References

Tables and figures should communicate relevant findings clearly, use accurate labels, and follow the formatting and resolution requirements specified by the target journal. References should remain relevant, accurately formatted, and sufficiently current, while every cited source must appear in the reference list and support the associated statement.

Scholarly Contribution and Practical Relevance

A publishable manuscript should explain what the findings contribute to existing literature and why the research matters within its academic or professional context. Authors should connect their results with previous studies, explain agreements or differences, acknowledge limitations, and identify reasonable theoretical, methodological, policy, or practical implications.

Compliance with Journal Requirements

Even a strong manuscript may receive desk rejection when its topic, article type, word count, structure, or referencing style conflicts with the journal’s requirements. Researchers should examine the journal’s aims, scope, recent publications, author instructions, submission checklist, and ethical policies before preparing the final manuscript.

Specific Considerations for Q2 Journals-

• Sturdy Research: Q2 journals are looking for convincing research that is beneficial for the body of knowledge.
• Methodological Soundness: Studies that were well designed and well implemented.
• Niche Topics: Areas of research which may be more specific or narrow scope but are nevertheless important to the scientific community.

How Should Researchers Choose Between Q1, Q2, Q3, and Q4 Journals?

Choosing an appropriate journal requires more than selecting the highest available quartile because the journal must match the manuscript’s subject, methodology, audience, and academic purpose. Q1 and Q2 journals generally offer greater citation visibility and wider academic recognition, although they may apply stricter editorial screening and receive larger submission volumes. Q3 and Q4 journals may remain suitable for specialised, regional, applied, or emerging research when they maintain legitimate indexing and appropriate peer-review standards.

A lower quartile does not automatically indicate poor quality, just as a Q1 position cannot guarantee the reliability of every article published within that journal. Researchers should examine the ranking database, subject category, reporting year, journal scope, publication charges, ethical policies, and institutional acceptance before making their final selection.

The most suitable journal is one that matches the manuscript’s contribution while meeting the researcher’s university, funding, promotion, or degree-completion requirements. Researchers should verify every journal near the submission date because quartile rankings and indexing records may change between reporting periods.
