Today, it would not be possible because of school entry age requirements, however in 1970, I passed State Boards in Pennsylvania (long before N-CLEX) when I was 19 years old. I was one of the youngest RNs in the state at that time. I entered my 3 year diploma program at age 16. During my freshman year, the State Board of Nursing eliminated the age requirement to sit for Boards, so I was able to take them without a problem.
