These refer to quartiles — a ranking system used to assess the relative importance of scientific journals in their respective subject categories.

📊 Quartile Classification (Q1 to Q4)

Journals are ranked into 4 quartiles based on impact and citation metrics:

QuartileDescriptionQ1Top 25% of journals in the fieldQ225%–50% rangeQ350%–75% rangeQ4Bottom 25%

This ranking is typically based on metrics like:

• CiteScore (from Scopus)
• Impact Factor (from Web of Science)
• SJR – SCImago Journal Rank

🧠 Example: In a category like "Management," if there are 100 journals, the top 25 by SJR/CiteScore would be Q1, the next 25 are Q2, and so on.

🔍 What Is Scopus Indexing?

📚 Scopus is a large abstract and citation database run by Elsevier, covering peer-reviewed literature: journals, books, and conference proceedings.

If a journal is "Scopus indexed," it means:

• It is included in the Scopus database
• It has met quality criteria, such as peer review, regular publishing schedule, and international relevance
• Its content is tracked for citations and metrics like CiteScore, SJR, SNIP, etc.

🔗 Scopus-indexed journals are considered reputable and are often required for academic promotions, Ph.D. submissions, and UGC CARE recognition (in India, for example).
