SPS Superintendent Anne Wilson confirmed the resignation of Brooke Patterson but would not go into further detail.
"I don't usually comment (when faculty members leave)," she said.
Wilson said the position is already filled.
A former SPS teacher who wished not to be named said Patterson gave just a one-week notice.
A message left for Curtis Principal Stephen Lambert was not immediately returned.
A message left for Patterson was also not immediately returned.
JFK Principal Brian Daniels announced Patterson's hiring in an October online newsletter to Hudson parents.
Patterson also spent 10 years at Perkins School.
