I applied to WLU online part-time, MSW advanced standing (I already have a BSW) for September 2020 start and was waitlisted today. I was notified by email. There are approx 43 spots on the waitlist and they will not let you know where you are on the waitlist. Response is required by May 29 if I accept or decline a spot on the waitlist. Waitlist will stay open until August 31, 2020. I just checked LORIS and there is no update, it still shows my application details. I will be declining to go on the waitlist as I've accepted a spot elsewhere.
Posting this for any future applicants who obsess and read through old posts like I did.
Good luck to everyone.
