Employers could ask for varying qualifications and experience. You may have an advantage with a BTEC HNC/HND or degree in supply chain management, logistics or business studies, but this is not essential if you have relevant work experience.
You could start as an administrator or assistant in a company's purchasing department, and work your way up to manager as you gain experience and professional qualifications from the Chartered Institute of Purchasing and Supply (CIPS).
In fashion retail, employers may prefer you to have qualifications and technical knowledge. .
You may be able to join some large companies through a management training scheme.
You will usually need a degree (in any subject) to get onto this type of scheme, although some employers will recruit people with A levels or similar qualifications. Most employers expect purchasing managers to have or be working towards membership of CIPS.
If you do not have an accredited degree in supply chain management, you can study for CIPS professional qualifications while you are working in a purchasing department. See the CIPS website for a list of accredited degrees and postgraduate courses, and more details about their qualifications and membership.
