I just called financial aid. The person who answered was extremely kind and helpful; she said Wake Forest is not using IDOC. She confessed she is new to the job so she confirmed with someone above her, and they are not using IDOC. So according to her, our financial aid responsibilities are done following submission of FAFSA and CSS. She even took the time to confirm that they received my CSS profile, which I told her was unnecessary, but it was still nice to have confirmation that they see it on their end.
For anyone working on CSS for Wake Forest: according to their financial aid office (March 7), they are not using IDOC this year for incoming students. CSS mentions that Wake Forest is not participating in document upload, but Wake Forest's website contradicts that at at least one location. I am deferred post interview myself, but this should be helpful for the March 15th financial aid "deadline."
