In answer to this, and hopefully to add a bit of additional insight, I was asked to send in my WICHE certification as part of the secondary, but it was not a prerequisite to receiving or submitting said secondary. Furthermore, though I have been verified through my state certification office, the secondary still says "incomplete" in that section (and I have an upcoming interview at Utah). I had been in contact with Utah regarding the certification before submitting my secondary, and I followed up with them this week. They told me that, though the secondary may not update to reflect that my certification component is "complete," I was good to go. Obviously I would check directly with them for your individual case though. Hope this helps.
