Before you decide what parts of the ILO you are focusing on when choosing a rubric, you must also decide what TYPE of rubric you need. The TYPE of rubric can be decided by asking: What do I plan to use the rubric for? There are multiple varieties of rubrics that you may use to evaluate students. The two main types of rubrics in practical use at universities are Scoring / Assignment Rubrics and Developmental / Assessment Rubrics.
For instance Lincoln University uses Developmental / Assessment Rubrics to assess student development from novice to master (1-4) in the ILO areas, and this is the rubric used for assessment. You may use a rubric for assignments in your 100 level course, however, they likely will not developmentally "master" the ILO until a 300 or 400 level course.
