Understanding WoS Q1, Q2, Q3, and Q4 Journals: A Complete Guide
For researchers and academicians, publishing in high-quality journals is not just a milestone—it’s a validation of their hard work and contribution to their field. One of the most respected and widely recognized journal indexing services is the Web of Science (WoS). If you're new to research publishing, you've likely heard about Q1, Q2, Q3, and Q4 journals. But what do these quartile rankings mean? And how do they affect your research career?
In this complete guide, we will break down the concept of WoS journal quartiles, how they're determined, and why they matter.
What is Web of Science (WoS)?
Web of Science (WoS) is a trusted database maintained by Clarivate Analytics, indexing high-impact scientific and scholarly journals across various disciplines. It includes citation indexes and provides tools for tracking citation data, impact factors, and research influence.
What are Quartiles (Q1–Q4) in WoS?
Journals indexed in WoS are ranked into four quartiles based on their Impact Factor (IF) within a specific category:
| Quartile | Rank Range in Category | Description |
|---|---|---|
| Q1 | Top 25% | Highest ranked, most reputed journals |
| Q2 | 25%–50% | High quality, solid journals |
| Q3 | 50%–75% | Moderate impact journals |
| Q4 | Bottom 25% | Lower-ranked journals |
