Assessment Form: Scale

Selecting the Right Assessment Scale for Your Assessment

Choosing the correct assessment scale is a crucial step in creating your assessment. The scale determines the grade based on the candidate's score percentage and the assessment's pass mark.

Setting Up Assessment Scales

The assessment scale will define a grade depending on the percentage the candidates score and the passmark of the assessment scale. Therefor it's important to setup the correct scale + percentage.

Assessment scales are configured in the Admin section under 'Assessment scales. These scales are customizable. As an author, you can select an existing scale and modify the Pass Mark for your Assessment Form. Changes to the Pass Mark will automatically recalibrate the grades before and after it, distributing them evenly.
