nformation for nurses
Please check that your training in your home country matches our requirements. These are that you should have completed a three year full time course or a course totalling 4600 hours at post secondary level leading to registration as a general nurse. At least half of this course, 2,300 hours, must be in clinical or practical training, and at least one third, 1,533 hours, must be theoretical training.
The course must include theoretical and practical instruction in general and specialist medicine, general and specialist surgery, childcare and paediatrics, maternity (obstetric) care, mental health and psychiatry, care of the elderly, community or primary care nursing.
If you trained in the USA and have an associate in science degree in nursing (ASDN) that was below three full time years in length, you will not meet our requirements for registration. We will consider your application if your programme was three full time years or more, and if you undertook a bachelor of science degree in nursing (BSN).
If your application meets our minimum standards, you will have to complete an overseas nursing programme. The programme sets out common entry standards, a compulsory 20-day period of protected learning and, where appropriate, a period of supervised practice. We strongly recommend that you secure your place on a programme before travelling to the UK.
you may find that agencies will not employ you until you have done the 20 day training period
