They are referring to the NJ DCA Checklist. You can log in and it has a list of all of your documents (fees, application status, references etc) and the dates they were received. I check this like a madman waiting for approval to sit. Rumor has it, sometimes they might input your pass into the system so it shows up in the checklist even before you are notified by NCEES/the State itself. It seems like it's random draw and there's no science to it.
It took them weeks, even a month or so after I got my pass email to update it for me.
