The “best” degree is the one that helps you to prepare for the career you desire.  1. A bachelor’s degree in education usually suffices for a beginning teacher, though many do go on to earn a master’s degree to increase their knowledge and salary.  2. Principals typically hold an MEd in education leadership or education administration.  3. Instructional coordinators benefit from a master’s in curriculum and instruction.  4. School counselors need a master’s in school counseling.  5. A master’s in library science or information studies looks good on an aspiring librarian’s resume.
