This category contains articles that have been rated as Portal-Class according to the WP 1.0 Assessment Scale by WikiProject Schools. Articles are automatically placed in this category when the corresponding rating is given as the value of the |class= parameter in the project template; see the Assessment Dept. for more information.
Note: You should not assign any A-, FA-, FL-, FM- or GA-Class assessments on your own. Those article assessments must be approved through the Wikipedia policies governing quality control and require a formal peer review prior to assigning them.
