Hi, I am a secondary international school maths teacher, teaching outside the UK. I am considering studying for my 'Masters in International Education' with a speciality in leadership whilst working full time through an Australian university who offer online classes. I feel that when I look at senior leadership level job adverts they're all saying that a high level degree is necessary. I presume they mean higher than a masters? But is a masters a good step to the higher level like getting a PHD or Doctorate? I'm getting positive reactions and offered promotions and extra responsibilities quickly once in a job. However, I don't want to limit myself to only getting promoted on the job. I'd like my CV to reflect more of my skills and for me to get interviews eventually for higher level positions like head of departments outside my own school perhaps. I'm thinking long term, I'm only 3 years into teaching. But I do want my CV to look better qualifications wise and long term to be in senior leadership so I thought maybe get a start now? Am I more likely to get a head of department role with such qualifications? Or what are people really looking for on a CV for you to jump up the ladder? All opinions, and experience on this will be much appreciated as I'll have to give up a lot of time studying.
