Today in education rubrics are one of the most important tools teachers have to grade assignments. With data collection rules and authentic assessments rubrics allow teachers to grade assignments easily and transparently. They also give the students the information they need to succeed at the assignment. No longer do they need to ask themselves what the teacher wants the rubric tells them.
Rcampus (http://www.rcampus.com/indexrubric.cfm) is a website that teachers create rubrics on. This site has thousands of rubrics that are created by teachers all over the world. Just a quick search can give you access to these rubrics
For example a search for a writing assignment rubric gave me this one (http://www.rcampus.com/rubricshowc.cfm?code=X3X3X8&sp=yes). You can use this rubric as is or you can create an account and edit it to make it your own.
If you create an account you can also make rubrics from scratch and share them with the world.
Another advantage of making your rubrics online with this site or others like it is you can embed your rubric on your personal website or share the link with your students so they can access it online without having to print out copies for everyone.
