When you have added a diagnostic assessment to a pathway (see Create a Diagnostic Assessment if you're unsure how to do this), you will be given the opportunity to create a Stand-alone Assessment by ticking the Stand-alone Assessment box.
You can create a stand-alone assessment to assign to Users without building a pathway which allows you to register Users onto the assessment only.
Tick the Stand-alone Assessment checkbox and click on the Save Diagnostic at the bottom of the list of activities.
If you do not tick this box, the diagnostic assessment will be included as part of the pathway and Users will be directed to complete it prior to any activities within the pathway (although they can click on a button to skip the assessment and take them straight to the learning if they prefer).
If the results of the diagnostic assessment identify a learning need, Users will be directed to the related learning.
