  • Apply appropriate theoretical and practical methods to design, develop, manufacture, construct, commission, operate, maintain, decommission, and re-cycle engineering processes, systems and products.
  • Prove technical and commercial management.
  • Demonstrate effective communication and interpersonal skills.
  • Demonstrate a personal commitment to professional standards, recognising obligations to society, the profession and the environment.
  • Once registered, you must maintain your status through meeting continuing professional development requirements each year

Guidance on supporters
For all levels of registration, you are required to provide two supporters. These supporters must be able to verify the information in your application. Sometimes it may be necessary to provide the details of a third supporter however this is optional. While it is preferable if your supporter is themselves professionally registered it is not mandatory.

Areas to consider when choosing your supporters:

First supporter:  this must be someone who knows you or has known you professionally, working at a senior level to you and with direct knowledge of your role and responsibilities.  This could be fulfilled by your current line manager, employer, head of department or faculty, head teacher or training scheme mentor.

Second supporter: a supporter who knows or has known you professionally at a relevant point in your career. 

Optional third supporter: a third supporter may be necessary if your application covers periods spent at several different organisations or you undertake consultancy work.

Please ensure that between them, your supporters are willing and able to verify your experience. They should be contactable by email for several months after you submit your application. Supporters will be sent links to the form they need to complete online via a generic IOP email address. Please ask your supporters to provide an email address that doesn’t have a high firewall as this can delay your application.
