If you want to work at the top of your profession you will usually need a Professional Qualification.
Professional qualifications aim to develop knowledge and skills required for specific jobs in different fields and industries. They are normally promoted by professional bodies and are subject to European directives.
Professional qualification courses can last from a few weeks to a couple of years, depending on the level of qualification and the time spent working on it - part time or full time. Also, a mix of studying and working in the field is often required when getting a professional qualification.
