We have a series that is desperately requesting to move from an always required survey (before claiming credit) to a required quarterly survey instead.
We are considering the logistics of this as in the past when we had optional surveys for every session we’d receive less than a handful of completions and had similar results with a paper “required” quarterly survey (attendees would just skip out on claiming credits for that session so as to not complete the form 
)
Is there a way to reference a webform within a series, limit responses to 1 per user, and have it so if the form has been previously completed by the learner they are then able to proceed to the next part of the course? If this is possible, then we could create one survey per quarter and reference the webform it within all of the sessions taking place for that quarter, this way the learner is only requested to complete it once but can’t skip attending the sessions for an entire quarter to forgoe completing the form.
Other than this does anyone have any suggestions?
