how much pension you can collect during retirement drectly related to your salary of your working years. For administrator, such as a superintentant, their salary is generally above 200k, and their pension is of course, high. for average teacher, the number is not pretty. This is data available: average NY teacher pension: 38924. Still, a few persons got more than 200k annual pension. If your kids has a choice, and no special interest as a teacher, never choose this profession.
