If you’re an experienced engineer with the skills to demonstrate a high level of professional competency, becoming an Associate could be for you.

Recent changes to the Associate grade open this option up to members from all around the world to demonstrate professional competency. Now you can become a professional member of the Institution, gain the AIStructE designation, and register as a Chartered Engineer (CEng) by passing the Professional Review Interview.

Eligible members will be registered as an 'Associate of the Institution of Structural Engineers'. Please note that you will not be able to use the title 'Chartered Structural Engineer' as this is only avaialble to those who have also passed the Chartered Membership Exam or equivalent.

If you are already professionally registered with an Institution-approved body, you may be eligible to apply for the Associate grade. Details can be found further down the page.

Meet IStructE members in your area through our Regional Groups and events, and get insight into the structural engineering community.
