Pegging

Pegging schemes are used to map the internal scores maintained in Chalk & Wire database to external scores such as percentages and letter grades. Once a pegging scheme has been created and linked to a rubric, assessments can be done using external scores. In addition, reports in CWReporter can use either internal scores or the pegged external scale.

Create a Pegging Scheme

When creating a pegging scheme, use a descriptive title that describes the relationship between the internal and external score, rather than a title that references 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.

Click the 'Pegging' option on the Admin drop-down menu.

On the 'Pegging' page, click on the 'Add Pegging Scheme' link.

Give your pegging scheme a descriptive label. Keep in mind that you may apply a generic pegging scheme to more than one rubric.

Setting Values

Set the high internal score to equal the high internal score of the rubric that you chose. If you chose multiple rubrics, they must all have the same high internal score.

Set the high and low external scores to equal the high and low scores on your external scale. The system will calculate the in-between scores in equal increments. If you specify alternative pegs, the system will configure the in-between scores in corresponding uneven increments.

You may also choose to use letter grades as pegs. In this case, each level should be assigned a letter grade.
