Wikipedia:WikiProject Dinosaurs/Assessment

Welcome to the assessment department of WikiProject Dinosaurs! This department focuses on assessing the quality of Wikipedia's Dinosaur articles. While much of the work is done in conjunction with the WP:1.0 program, the article ratings are also used within the project itself to aid in recognising excellent contributions and identifying topics in need of further work.

Frequently asked questions

 * How can I get my article rated? : Please list it in the section for assessment requests below.
 * Who can assess articles? : Any member of WikiProject Dinosaurs is free to add—or change—the rating of an article. Please add your name to the list of participants if you wish to assess articles on a regular basis.
