Although this area of work is open to all graduates, an HND or degree in the following subjects may increase your chances:
accounting and finance;
business studies;
fashion management;
marketing;
retail management.
However, there may be exceptions where the retailer is a specialist in its field and a more relevant HND or degree may be preferred.
A pre-entry postgraduate qualification is not usually required, although a proportion of retail managers do undertake relevant postgraduate study. Search for postgraduate courses in retail management.
