The Chicago Hip-Hop History Project: Wikipedia grading methodology
Wikipedia Article Grading Distribution Analysis is a study examining the relationship between internal article quality and Wikipedia's established Content grading system. The analysis explores how grading correlates with prioritization of research, and how articles without Wikipedia counterparts may represent the most valuable opportunities for content development.
Overview
The study analyzed 170 articles, 104 of which have corresponding Wikipedia pages. The grading distribution among these Wikipedia-supported articles approximates a normal distribution.
Given that only approximately 0.0961% of Wikipedia articles are Featured Articles and 0.584% are Good Articles, the presence of two Good Article–graded entries among the 104 studied represents a relatively strong performance.
Key Takeaways
- Articles graded lower (e.g., C or Start-Class) are considered higher priority for research and improvement.
- The 66 articles without a corresponding Wikipedia page are of particular importance since they represent unique contributions to public knowledge.
- Outlier cases, such as the article on 2hollis—which ranks 5th in Wikipedia pageviews yet retains a Start-Class grade—highlight discrepancies between audience demand and research depth.
- Articles often plateau in quality improvement between C and B grades, suggesting that progression to GA or FA levels usually results from extra editorial investment rather than inherent topic notability.

Wikipedia Grading Methodology
Wikipedia utilizes a comprehensive quality scale to assess the maturity, accuracy, and completeness of its articles. The following summarizes key criteria:
Featured Article (FA)
An article that has passed an in-depth review via Featured article candidates. It must be:
- Well-written and professional in tone
- Comprehensive and well-researched
- Neutral and verifiable
- Stable and free of edit wars
- Properly formatted and cited
- Accompanied by relevant, properly licensed media
Featured List (FL)
Articles that comprehensively list items within a defined scope, meeting professional writing standards and accessibility requirements.
Featured Media (FM)
Images, videos, or animations judged among Wikipedia’s best, based on technical quality, encyclopedic value, and licensing.
Good Article (GA)
Articles that meet the Good article criteria, characterized by clear writing, reliable sourcing, neutrality, and stability.
A-Class
Well-organized, comprehensive articles nearing FA standards but not yet nominated.
B-Class
Substantially complete articles that meet most criteria for a Good Article but require improvement in structure, sourcing, or style.
C-Class
Substantial content that may lack important details or sources; requires significant cleanup.
Start-Class
Developing articles with meaningful but incomplete content.
Stub-Class
Very short entries that provide only minimal descriptive information.
List-Class
Articles that are primarily composed of lists or indexes.
Analysis and Implications
The data indicate that grading serves as an effective prioritization mechanism. Articles with lower grades—particularly those without existing Wikipedia counterparts—represent high-value opportunities for original research and knowledge expansion.
The study also identifies a structural bottleneck between C- and B-Class development, implying that many articles require targeted editorial engagement rather than solely increased public attention to achieve higher quality levels.
