If your aim is to take up a professional career in psychology, you will need to be prepared to undertake further study which requires independent but supervised research in the area which interests you e.g. neuroscience, developmental psychology, psychiatry or pharmacology.  About a quarter of our graduates go on to take postgraduate degrees (a taught masters or a doctorate) either here at Oxford, Cambridge or other institutions within the United Kingdom or overseas.   

After completing a taught masters or doctorate, post-doctoral students may then develop a research career in universities, or in applied laboratories in government agencies or industrial companies and consultancies.

A doctorate in Clinical Psychology is a popular option, with good career prospects.  It requires a three-year period of postgraduate training (DClinPsy) which is usually preceded by gaining some practical experience in a job related to mental health. Educational and Occupational Psychology are other fields with their own postgraduate training requirements.                                           

There are also careers which although not strictly psychology, are closely related and benefit from psychological training: for example personnel, probation and social work.

You should realise, however, psychology degrees give you a general training in systematic analysis of questions about human beings, including numeracy, literacy, and IT skills.  As such, they are widely regarded as excellent training for a very wide range of careers in commerce, government, industry, media, and the professions.
