TLDR: If I appeal a grade, should the assessor be able to uphold my appeal but then give other reasons to not pass me?
I'm studying at the moment. I've submitted four pieces of c/w so far. I passed the first one. The second and third I was referred, which means they wanted me to resubmit with some changes. I appealed both of these (the second on the grounds the info they wanted wasn't a requirement in the assessment criteria and the third on the grounds the info they needed HAD been included in the appendix). Both my appeals were upheld and I passed.
So onto my fourth, with waning confidence in the competence of the assessors. I was referred again. The thing they wanted, again, was not in the assessment criteria. I appealed on these grounds. The appeal was not upheld and the assessor just reiterated that x y and z was needed. I appealed again asking that they direct me to the content where this was set out as a requirement. This time the assessor agreed that it wasn't set out in the assessment criteria but then came up with something else, completely different, I needed to do to pass.
AIBU to think if I appeal a grade the assessor should not be upholding my appeal and then coming up with secondary reasons for me to not pass? I've checked the very brief appeals policy and there is no mention of this.
