Michael,
I think we are interpreting the word "challenge" differently. I was suggesting that the stated requirements are open to LEGAL challenge (as in, the technical standards are discriminatory in the way they are written). You have to find a way to work with your colleagues from that department to try to get them to recognize the inflexibility of their policies (and the impact), while still being straightforward with the student about the uphill battle he/she may face within your institution because of those existing (restrictive) technical standards.
