You ask a great question that has somewhat of a loaded answer. The title "nurse" can be applied broadly depending the level of educational preparation and the license a nurse possess. The National Council of State Boards of Nursing (NCSBN) identifies 3 levels of nursing which I've listed in order of least amount of education to greatest: Licensed Practical or Vocational Nurse (LPN/LVN), Registered Nurse (RN), and Advanced Practice Registered Nurse (APRN) (https://www.ncsbn.org/nursing-terms.htm). LPN/LVN nurses typically complete a program that is 1 year of full-time coursework and receive a certificate of completion which then would qualify the student to take the NCLEX-PN. RNs typically have a least an associates degree in nursing science or a bachelors of science in nursing in order for the student to qualify to take the NCLEX-RN. There are some diploma programs that are usually hospital or facility based that offer a certificate of completion, similar to an LVN/LPN arrangement though these are not common. Finally, APRNs have a minimum of a masters of science in nursing or a doctorate of nursing practice or PhD. APRNs have different certification exams depending on the specialty the APRN selects. NursingCAS.org has a fantastic chart that details all of this further (https://www.nursingcas.org/wp-content/uploads/2018/08/Nursing-Degree-Comparison-Updated.pdf).

Hope you get what you are looking from. With new NEP 2020 getting announced in India, things may slowly start chasing but I believe existing would continue
