File Uploads
If the school has turned on the feature to allow file uploads (images or pdf), you will seen an option to attach files to your submissions.
This is sometimes used if you have printed copy of a competency to allow an evaluator that is not in CompKeepr to evaluate you, you can instead send your competency to a clinical instructor or school account and attach the file. They can then verify the content of the file and complete the evaluation as it appears in the uploaded file.
There is no other option for files to be attached to competency submission, the student must add the file if it is required.
