I took the information in the AP course guide that I received at training and developed a teacher-friendly rubric that helps when grading e-mail reply writing practice. I like using this rubric because it is on a 1-5 scale so students can receive feedback on certain aspects of their writing. Also, students can use this rubric in peer grading and self-evaluation.
This is a total time-saver! Save time and use this rubric instead of creating your own :)
