Simplified guides have a lot of value for students, as they offer information on the fly.

EIT has decades of experience to assist students, and have published an online and in-depth list of abbreviations students will need to know while completing an engineering course. You can access our Acronym Master list here.

The beauty of engineering acronyms is that they are universally understood, and a good way to be in touch with fellow engineers.

As a refresher, here are some common acronyms you’ll see often while completing a course in engineering.

A simple guide to engineering accords

• EIT have three accords.

• One of the accords which is the Dublin accord only deals with Advanced Diploma courses.

• At the moment EIT has only three courses accredited under the Dublin accord which are the DEE, DIA and the DME courses.

• EIT has applied for the DEP and the DCS courses to be added under the Dublin accord.  

• The second accord which is the Sydney accord, deals with the Bachelor’s programmes.

• The third accord deals with your Masters’s courses or post-graduate which is the Washington Accord.

Country Acronyms

The thrilling part of engineering is that information comes from each nation on the planet, and it’s always worthwhile to know how different countries are abbreviated.

A standard form of country abbreviations is two-letter acronyms and three-letter acronyms.
