What is the highest qualification in civil engineering?

The highest academic qualifications in civil engineering are the PhD or EngD (Doctor of Philosophy or Doctor of Engineering in Civil Engineering respectively).

The highest professional qualification depends on the country. In the UK this is Chartered Engineer status and the individual will also be either a Member or Fellow of the Institution of Civil Engineers (MICE / FICE), or Institution of Structural Engineers (MIStrucE / FIStrucE). In the US, a professional engineer will be granted Professional Engineer status (and is entitled to use the post-nominal letters PE).
