I would suggest learning as much as you can on the job and asking your employer to pay for quals as part of your continued personal development.If you are interested in a general project management role, then Prince 2 would be a good choice. Also suitable for project management roles outside of consultancy. ITIL is a popular choice for the IT Service Management industry.I believe some of the big 4 still ask their consultants to work towards the ACA, i guess good if you want to transfer into audit/accountacy later in life!Dependent on what your speciality area is, other quals could include chartership or diplomas in specialist areas (e.g CIPD, CIPS, Six Sigma MBB, etc).
