I have been offered a Ph.D. position in the USA where the offer says 'the admission comes with an 11 month per year teaching assistantship that carries a $2,000/month stipend, health insurance, and a scholarship to cover your tuition. My question is why do they mention 11 months? Does that mean theythat I will not pay me anotherget payed for the 12th month? I am an international student so I am very confused about the offer. Should I ask the program coordinator regarding this?
