My son is a USCGA Scholar's program candidate pending a Medical Waiver for Colorblindness. The Scholar's Handbook indicates a favorable waiver if the candidate passes the Farnsworth exam, which he did. However, we were informed this week that he must take a newly instituted test, Waggoner Computerized Color Vision Test (CCVT). This directive began March 1, 2018. Under the circumstances I feel the goalposts have been moved at the last moment. If my son fails the new test, what chances are there for an appeal and ultimate waiver? Any suggestions for how to advocate for my son?
