What is the difference between a nursing assistant and a Level 3 nursing assistant?

A nursing assistant gives daily patient care and basic health support. A Level 3 nursing assistant has studied wider care topics, such as safeguarding, infection control, communication, medication awareness, and record keeping. In the UK, Level 3 does not equal NHS Band 3 or a regulated nursing qualification.
