This is the grading criteria that I use as a basis for all of my rubrics assessing students' writing in Spanish. This particular version is very suitable for assessing journal entries; however it could be tweaked to fit a variety of writing assignments.
The criteria included are grammatical accuracy, completion, overall quality of writing, use of class time, and participation in proofreading. Students may be graded as "Needs Improvement," "Developing," or "Exemplary." I typically enter a point value at the top of the rubric for each of these three categories, then add the total possible point value at the bottom of the rubric.
I hope you find this helpful as a starting point for creating your own rubrics! Tweak away to fit your own needs. Please leave comments, feedback, and suggestions! All are greatly appreciated!
