Guide to Leaving Cert Subjects

Subject Choice for LC

Towards the end of Third Year (or Transition Year if you are taking it), students will be asked to choose which subjects they would like to study for their Leaving Cert.

First you must consider which Leaving Cert programme you will take. This will depend largely on what is offered in your school. Explore The Three Leaving Certs here.

There are usually more subject options available for Leaving Cert than Junior Cycle, which means you can focus your studies more on the areas you are interested in.

Your choice of subjects in the Leaving Cert may effect what courses or employment options are available to you after you leave school, so it is important to take the time to choose carefully.

What subjects did you take in school and how have these influenced your career path?

For my Leaving Cert, my eight subjects were English, Irish, Maths, German, French, Business, Physics and Applied Maths. Looking back now I think I had a really broad list of subjects and this theme resonates today. I can get quite impatient and bored quite quickly so I really enjoy the different aspects of subjects. This is linked to the ability to get involved in different things at work, which keep things interesting.

Engineering, Technical Drawing and Construction/Woodwork have influenced my decision. I enjoyed these subjects as they have a practical aspect which keeps them interesting.

What subjects did you take in school and how have these influenced your career path?

In secondary school, for my Leaving Certificate I chose Biology as one of my optional subjects, and that’s the one that really stood to me for my career, along with the compulsory subjects like English and Maths. Looking back, I think Agricultural Science would also have been a good choice because it overlaps with what I do now. If I had the chance again, I’d also consider Computer Science, because a lot of statistical software involves coding, or Geography, which links closely with the environmental work I do. These subjects would all have been very relevant for the type of job I have today.
