'Education Administrator' is just a fancy phrase for a head teacher or a principal. This is someone who's been working on the front line of teaching for years, and displayed sufficient aptitude for it to be given a school of their own to run. Sometimes, they may even preside over a whole range of schools in an area. They'll still have excellent teaching and communication skills, but they must also understand business.
All schools have a budget. How are you going to make yours run efficiently? How will you set the timetable, and make sure each department has the resources it needs? Most education administrators have a master's in leadership or education, and sometimes both. The role is part educator, part accountancy and part politician. It's also very stressful. No wonder it pays so well! It's not all stress and strain though - it's a role in which you can make a material difference to the future of children.
