We had the situation of teachers/etc inexperienced with gateway’s requirements. We ended up helping out by gathering hard copies from most and mailing in one package via Fed Ex. That extra effort on our part gave peace of mind but also appreciated the added effort requested of teachers.
Regarding the dangerous minds of teachers bias? Ironically for you, the environment at most private schools celebrate their teachers ability to influence the dialogue with their students. That pedagogy is exactly what you are buying into. Hope you decide to celebrate that too.
