SOC code for IT Consultant

Hi
My wife will be applying for a PR in March. She works for IBM and in Business Consulting. Her salary is 54K £/per anum. Can anyone advise what SOC code she should use? Her job title is Managing Consultant and she does work around HR Systems Implementations. We are not sure what SOC code to use to match her salary - any suggestions from those with similar background in IT Consulting

Thanks
