My apologies in advance as this is not precisely a Stata question.
Though I'm quite sure I can use Stata to help answer it.

I'm estimating an ordered logit -ologit - in Stata, since my dependent
variable is final class letter grade. I realize the strong proportional
odds assumption of the model, ie parallel regressions, and test for
those using Long and Freese's -brant- test. I also use Wolfe and Gould's

See especially this handout on interpreting results, especially the section that starts on slide 10:
