This rubric was specifically designed for use with third grade ELA standards. I use this as a body of evidence for standards-based grading. Students write sentences using third grade level spelling and vocabulary words. Below is a list of essential skills/learning targets in student-friendly language that are included on the rubric:
COMPLETE SENTENCES: I can show that I know how to write sentences correctly.
CAPITAL LETTERS: I can capitalize words in titles and proper nouns.
PUNCTUATION: I can use correct punctuation within a sentence.
SPELLING: I can spell commonly used words correctly.
