* Country: Educational requirements differ widely across the globe.
* Level of education taught: Teaching preschool requires less education than teaching at the university level.
* Subject matter: Some specialized subjects (like engineering or advanced mathematics) may require higher levels of expertise and thus advanced degrees.
* Specific school/institution: Some prestigious private schools or universities might prefer or require candidates with doctorates (PhDs) even for K-12 teaching positions.
While a bachelor's degree is generally the *minimum* requirement for most K-12 teaching positions in many countries, some teachers pursue master's degrees, and some even doctorates (PhDs) to advance their careers or specialize in a particular area. A doctorate might be necessary for positions like university professorships or certain highly specialized roles in education.
