When submitting to SCI-indexed journals, researchers often encounter terms like  (Zone 1) or  (Zone 2). But what exactly do these classifications mean? And how do they affect the academic value, recognition, and evaluation outcome of your publication?

This article breaks down the difference between Zone 1 and Zone 2 journals under the SCI system, and how iconf.com helps you navigate your journal selection with clarity and strategy.

What Are SCI Zones?

The SCI zoning system (also known as "quartile ranking") is a way of classifying journals based on their Impact Factor (IF) within specific subject categories. It is typically divided into four levels:

These rankings are determined using Journal Citation Reports (JCR) by Clarivate Analytics.

Main Differences Between SCI Zone 1 and Zone 2

Feature	Zone 1 (Q1)	Zone 2 (Q2)
Impact Factor	Highest in the field	Moderately high
Academic Recognition	Extremely strong; often used for top-tier evaluations	Strong, but slightly less than Zone 1
Publishing Difficulty	Very competitive; low acceptance rate	High-quality, but acceptance is more accessible
Use in Evaluations	Favored in promotions, grants, PhD defense	Still highly valued, especially in applied research
Typical Journals	Flagship journals with global readership	Reputable journals with solid reputations

In general, Zone 1 = elite, while Zone 2 = high-level but not top-tier.

Why Does the SCI Zone Matter?

In many institutions and countries, SCI zones directly influence:

• Grant and funding eligibility

• Graduate thesis recognition (especially for PhD candidates)

• Academic promotions and tenure applications

• International collaboration opportunities

In some cases, a Zone 1 publication may be required to qualify for top-tier programs or research awards.

How Are the Zones Determined?

Zones are based on:

1. Subject category (e.g., Electrical Engineering, Environmental Science, etc.)

2. Journal Impact Factor ranking within that category

For example:
If a journal ranks in the top 25% of “Computer Science – Artificial Intelligence,” it is considered Zone 1 in that subject.

Important: A journal can be Zone 1 in one subject, and Zone 2 or 3 in another, depending on how it is indexed.

Final Thoughts

The difference between SCI Zone 1 and Zone 2 journals lies in impact, difficulty, and recognition. While both are high-quality, Zone 1 journals generally offer greater academic weight. However, Zone 2 journals remain a strategic and respected choice, especially when publishing high-level applied or interdisciplinary work.
