I used the Narrative Rubric from the ReadyGEN 2016 program and broke it down. Now I can assess students only on the areas they have had thorough instruction and practice. Ultimately they will be assessed on all components of the rubric, but until they are ready for that, this works great! These rubrics include the components as follows:
1. Focus & conventions (narrative)
2. Focus, organization & conventions (pourquoi tale)
3. Focus, organization & conventions (tall tale)
4. Focus, organization, development, conventions (tall tale)
These are EDITABLE to suit your needs. The language in thr rubrics changes slightly according to which type of narrative it is- marked in parentheses.
