Maybe someone could clarify further as I’m on the list but no outstanding certification..
afaik , outstanding cert is that you are on the certified list, ie called in for preemployment. When it expires , I believe you are taken off the list, so you will have to call or email to get back on the list when that happens.
My reference.. I was on outstanding cert, had an issue at preemployment, was removed from list, and had to email and call to get back on the list after resolving my issue.. I’m now waiting for call or email. I currently do not have an outstanding certification. My list number is in the low 1100’s.
