There are two steps to importing rubrics. In Step 1, you create a new rubric to import using the Rubric 'Form Builder' tool (Assessment Instruments > Import Instruments). The new rubric is saved on your computer as a tab delimited text file. In Step 2, the rubric is uploaded and appears in the list of rubrics on the 'Assessment Instrument' screen, where you can add performance level descriptors, if desired.
