For the Naval Academy this is a hard waiver to get, at USMA and USAFA it's not as tricky but due to naval service requirements it's tough. The number of waivers given from year to year varies, but there is always a cap (and you won't know what it is) on how many color blind or deficient students will be admitted and they are competing against each other in terms of grades and qualifications for one of very few waivers. Ball park I have been told it's about 10 (give or take) waivers a year for this condition. Also, anecdotally it seems that the waivers are often given to college re-applicants or students who have already completed a year of college and demonstrated success in higher learning and are a "safe bet" to give the waiver to. DS was turned down medically due to color deficiency for the class of 2026 but was encouraged to re-apply this cycle by the medical department with hopefully better odds of getting the waiver...although we still realize this is an uphill battle. It's a hard pill to swallow since he would most likely be at the USNA right now if it weren't something that he has no control over and doesn't really even affect him in his day to day life. But since his long term engineering goals are best met with the Navy he has decided to give it another go and see what happens.
