3. Arizona: Public Schools
According to a study conducted by personal finance website WalletHub, Arizona is the worst state in which to be a teacher. The state has extremely low public-school spending per student, low teacher salaries, and a high pupil-to-teacher ratio. Because of that, there is a high teacher turnover rate, which further minimizes the effectiveness of Arizona's public schools. Arizona falls No. 49 on the list for the worst school systems in the U.S.

In contrast, the best states for teachers include North Dakota, Pennsylvania, Wyoming, New Jersey, and Connecticut.
