The most common route in Kazakhstan is a medical college with a Nursing program. You can enroll after grade 9 or grade 11, and the program lasts a few years with plenty of practice in hospitals and clinics. After college, graduates pass a qualification exam and can start working as nurses.
There is also a university route: a bachelor's degree in nursing at a medical university, where admission is based on the UNT with biology and chemistry. This degree opens the way to senior nurse positions, teaching and managing nursing services. Many people work for a while after college and then continue their studies at university.
