Rubrics can be one of the trickiest things that a teacher needs to create. Sometimes it helps to start with a template, or use a site that helps you build your own rubric. Take a look at these sites for help in creating rubrics.
Rubrics4Teachers offers a LOT of pre-made rubrics covering a variety of subjects that are available for your use. You can search by subject matter or by term. This is a great site with a lot of free content, though the focus is on already created rubrics, not make-your-own.
Rubistar is an easy to use online rubric makers that also offers accounts (so you can store and access the rubrics you make), templates, and pre-made rubrics for a variety of subjects. Everything on the site is free.
iRubric is a pretty great tool. Like the others we’ve mentioned, it offers rubric building tools, and a searchable database of pre-existing rubrics from other teachers. It also offers an easy way to grade via the rubric: “just pull up a rubric from the gradebook, click, click, and you’re done. Rubric scores are automatically adjusted to the coursework grading scale and posted on the gradebook.” You even have the option to send a copy of the graded rubric to the students securely. Teachers and students can use the site for free, but if a whole school or district wants to set up a larger scale account, they offer paid options, too.
