The first step to medical career training is the education itself and this means going to school. This would mean having to read books, getting familiar with the theories involved and putting these knowledge into practice by actually performing the tasks called for depending on the situation in question.
The medical field is very broad and how each field or skill is taught would really vary depending on the school and the course. There is always the choice of going for a vocational school or even a trade school where courses including chemistry, math, science, physiology, anatomy, infection control and getting familiar with medical terminology.
After the basic courses are completed, only then can the student go forward for the advanced courses. Once the advanced courses are completed, the student will then be given a hands-on training that will involve practicing all of the theories that had been studied. Making a mistake on the theories and final task can mean the life and death of patients. This is the time where many of the students fail and are dropped from the roster. It can be very brutal way of weeding out the potential medical practitioner from those who only aspire to the career.
Despite the rigidity of the medical career training that causes some shortages in some sectors, there are still plenty of degree holders who are finding a hard time finding jobs. If this is the case, they have another recourse to fall back on: to work overseas. This is the reason why there are so many in the nursing and technical fields are applying for jobs overseas for if one country has a surfeit of graduates and professionals, another country has a shortage of them. This may mean having to take additional tests, but it is worth the efforts.
