I'm having the exact same debate! I've applied to both International education development and masters in development programs and I am not sure which type is best given my career goals.
My background- I studied international studies undergrad and then went into teaching through TFA. I taught immigrants in Houston for 3 years, did a teacher exchange in Uganda and now for the past year and half I have been teaching Cambodia. I've seen how access to quality education programs affects many different aspects of development- health, gender equality, human rights etc...
I'm interested in working in the NGO world on the larger impact of education programs (UNCIEF, UN, Save the Children). So I"m not sure if a international education vs international development program is a better fit. I've noticed the Education programs are a year long where as the development ones are two years- trying to also weigh the pros/cons of both.
I've been accepted to SAIS, Georgetown GHD, Trinity Dublin- Development practice, Columbia TC, and UPENN International edu devp and they all seem to have a good reputation, good faculty and good alumni outcomes.
Any advice/insights on what you've heard or decided and from those who've gone through the programs with similar career aspirations would be greatly appreciated!
