Pegging schemes are used to map the internal scores maintained in the database with external scores, such as percentages or letter grades. Once a pegging scheme has been created and attached to a rubric, assessments will be done using the external scale. Reports are available in the external (pegged) or internal scale in CWReporter by toggling the ‘Report Using Pegged External Scores’ option on the Options drop-down menu.
Assigning letter grade pegs - You may also choose to use letter grades as pegs. In this case, each level must have an assigned letter grade (not just the high and low levels).
Creating a new pegging scheme - Choose ‘Pegging’ from the ‘Admin’ drop-down list. Click the ‘Add New Pegging Scheme’ link on the ‘Pegging’ screen. Name your pegging scheme, keeping in mind that you may want to use it for other rubrics in the future (see ‘Things to consider about pegging’ ).
Click the ‘Add Peg’ button and enter a lower limit for the external score. Add another peg and enter the high internal score. Set the high internal peg score to match the high score of the rubric(s) that you have chosen. This is the high score on the existing rubric to which you will be applying the pegging scheme (peg map).
If you choose multiple rubrics, they must all have the same high internal score. Leave the low internal score set at zero. The system will assign the intermediary scores to correspond to pegs at equal intervals of 0.5. You may alternatively choose to set pegs at unequal intervals.
Deleting a pegging scheme - To delete a pegging scheme, you must first unlink all rubrics that have been assigned to it. To delete a pegging scheme, click the 'Delete' option in the 'Actions' drop-down menu.
Assessor view of pegging - When a pegging scheme is applied to a rubric, the assessor sees the external scale during assessment.
Things to consider about pegging - When creating a pegging scheme, use a descriptive title that describes the relationship between the internal and external score, rather than describing the rubric or the department of the rubric to which you are applying the scheme. In this way you will be able to use the same pegging scheme for multiple rubrics, where applicable.
