Welcome to the assessment department of the Geology WikiProject! This department focuses on assessing the quality of Wikipedia's articles about Geology. 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 recognizing excellent contributions and identifying topics in need of further work.
The class parameter rates the quality of the article. The possible values can be seen in the "Quality" column of the table at the top of this page. The quality scale is common to the majority of Wikipedia articles. See Wikipedia:Version 1.0 Editorial Team/Assessment#Grades for interpretation of the ratings.
