In brief... header image

Chemistry exists everywhere, not just in laboratories, but in every living thing on land and sea and in our bodies. Chemistry is often described as 'the central science' containing a lot of formulas. So, if you enjoyed Junior Cert Science and have done well in it, and in Maths, you should be a good candidate for Leaving Cert Chemistry.

Why Study this?header image

Why Study Chemistry

This subject aims to provide a relevant course for students who will complete their study of chemistry at this level while, at the same time, providing a foundation course for those who will continue to study chemistry or related subjects following completion of their Leaving Certificate. Chemistry is considered most useful for careers in Pharmacy, Ag Science, Medicine, Engineering, General Sciences and Biotechnology. 

 What kind of student would Chemistry suit?

  • If you enjoyed Junior Cert Science and you have done well in this and in Maths, you should be a good candidate for Leaving Cert Chemistry.
  • If you apply attention to detail and are able to describe the procedures of experiments and understand vocabulary.
  • Students considering a career in any scientific discipline, such as chemistry, biology, environmental science, medicine, pharmacology, or material science.


  • It is recommended that a student undertaking the chemistry course has a good understanding of Junior Cert Science at higher level.
  • Each student should have an aptitude for and an interest in laboratory work.
  • A student would be expected to have a reasonable level of Junior Cert Maths, either at higher or ordinary level.

Software Engineer - Karl Stanley
Karl Stanley, Smart FuturesFor my Leaving Cert. I took Maths - higher, Applied Maths - higher,  Physics - higher, Chemistry - higher, Music - higher, English - higher, German - higher, Irish - ordinary As you can see my abilities and interests were more in the maths+science sphere than anything else.

I was very lucky that at the time Mt. Temple had very capable maths+science teachers, which certainly made things easier for me. To be honest, in school I didn't really think about 3rd level or careers or anything until I was in 6th year (by which stage I'd already picked my subjects). I just picked the subjects I enjoyed and felt I had a natural knack for.

For the career I'm in now I don't think I could have picked better school subjects. It might have helped me to know a bit more about business-related subjects, but I had no interest in accountancy or commerce at the time.

I am considering taking an evening course in the legal+financial aspects to running a business to make up for this. However, as a teenager I think I was better off studying subjects that I had a genuine interest in, otherwise I would have found it very hard to motivate myself to study.

Design Engineer  - Tracey Roche
Tracey Roche, Analog Devices

My Leaving Cert subjects were as follows: English, Irish, Maths, French (obligatory subjects). My choice subjects were: Accounting, Physics & Chemistry. I did all honours subjects and I think doing honours Maths and English especially really help.

English is not immediately obvious when one thinks of a career in Engineering, but from the point of view of report writing and corresponding with team members and even customers via email etc, it is a very important skill to master.

I was not 100% sure of my career path at the time of choosing the above mentioned "choice-subjects". My way of thinking was, one business subject, one science and another one that I thought I might like or be good at. Physics, Chemistry and Accounting all have a common theme of maths and problem solving, this was my link into Electronic Engineering... In hindsight, had some form of technology or electronics courses been available in my school, I think these might have been helpful. I'm not sure which subject I would have replaced though!

Computer Programmer - Jason Ruane
Jason Ruane, Intel

In secondary school I took Physics and Chemistry since I loved science. I also took Business Organisation but that was for the life skills it teaches rather than an intrinsic desire. I would gladly have enjoyed doing all the science subjects, to the complete detriment of all others but in hind-sight I am glad I took a subject such as Biz. Org. as it gave a rounding aspect to my secondary schooling.

I would have liked to have done Technical Drawing possibly but had to make a choice. I was only mediocre in German and Irish but again am glad I did them for at least secondary school as it challenged me and I did not get too narrowly focused on the technical subjects (there was plenty of time for that in third-level). In hindsight I realise that Maths was more important than I imagined and the two science subjects stood me in good stead. The choices I made for the subject selection was made by my passion for the sciences. Luckily I was afforded this leeway as the points for my intended course were not particularly high at the time.

Consulting Engineer - Peter LaComber
Peter LaComber, CRH plc

I chose Physics, Chemistry and Technical Drawing as my optional subjects for the Leaving Certificate with a view to choosing an engineering course at third level.

These subjects certainly helped with first year in college as I had a foundation in those subjects to build on.

In hindsight, I would have chosen Applied Maths over Technical Drawing as the engineering course had a significant Applied Maths content.

Overall, I feel my subject choices were appropriate for my career choice.

Electronic Engineer - Shane Callanan
Shane Callanan, Smart FuturesWhen in I was in school I didn’t really have a definite career plan. However I did prefer the Science subjects in general over languages or Business type subjects. Along with the obligatory subjects, I continued with Physics, Chemistry and Honours Maths for my leaving certificate, not so much as a conscious career choice but because I liked them. However as it turned out these all helped me during my course, and they tied in with my career choice.

Horticulturist - Paul Dowling
Paul Dowling, TeagascBiology and Chemistry were my favorites. Another which I found useful was Woodwork. Unfortunately, I gave up Woodwork, which is a good practical subject too early. The subjects I really enjoyed the most were Biology and Chemistry. Other practical subjects like Metalwork or Orienteering have been helpful. Biology is most important for anyone going into Horticulture as it covers propagation and helps with the identification of plant names, species and families through the universal use of Latin. Chemistry is also helpful as the use of various chemicals is a constant in horticulture. The chemical content and dangers of fertilizers, herbicides and insecticides in use in Amenity Horticulture needs to be understood anyone going into this business.

Ambulance / Paramedic - Keith Hayes
Keith Hayes, Health Service ExecutiveIn school there was very poor attention given to, or ‘guidance’ towards suitable careers. I was lucky I knew what I wanted to do. This, looking back was disappointing because I had no drive to go to third level college. I knew all I needed to be a Paramedic was the Leaving Cert.

In the Leaving Cert I took English, Irish, Maths, French, Biology, Chemistry and History pretty much the standard, they didn’t really have much influence on my career choice. That said, Biology and Chemistry are a great foundation for studying medicine as a Paramedic.

Dancer - Megan McEvoy
Megan McEvoy, Languages ConnectAside from English, Irish and maths I did music, French, art and chemistry. I did business studies until the Junior Cert but dropped it then. Although I didn't enjoy business studies I really wish I had kept it on as had I known that I'd be self-employed in the future it would have helped me greatly in terms of tax, loans, self-marketing and starting a business.

Essentially I am now running a small business by being self-employed. While I didn't use French and ended up living in Spain for 4 years I do feel having had a second language in school made picking up Spanish easier for me and I was really willing to learn it. Music of course has helped greatly in my career as there is nothing worse than a dancer who has no sense of musicality. Music has always played a big part in my life and many teachers have commented on my strong sense of musicality through dance.

Energy Manager - Jonathan Pugsley
Jonathan Pugsley, Sustainable Energy Authority

Science Subjects: Maths, Physics, Biology, Tech drawing, Chemistry  - I loved these and they are very applicable for my current career path.

Data analysis and problem solving - it's all about number crunching at the end of the day when working on technical problems.

Arts, English, English Literature and French are subjects I was never really interested in at school, but have become more interested in the last 10 years, as they are very useful for communication purposes, and that is now a very big part of my job.

Course Overview header image

The subject aims to provide a relevant course for students who will complete their study of chemistry at this level while, at the same time, providing a foundation course for those who will continue to study chemistry or related subjects following completion of their Leaving Certificate.

The Leaving Cert. course follows on directly from Junior Cert Science, and deals with more topics in a lot more depth. The course includes 28 mandatory practical experiments which must be completed in the lab, as well as a written paper including questions on the experiments and examining the theory and applications of chemistry. There are an amount of calculations involved. Chemistry has been the second most popular science subject for some time now.

Quick facts

  • There is no element of continuous assessment but experimental copies must be available for inspection by State Examinations Commission

Course Contentheader image

The syllabus consists of approximately 70% pure chemistry; the remaining 30% deals with the social and applied aspects of chemistry.

The syllabus is comprised of all the essential and relevant topics within general chemistry. The major topics involved include the following:

  1. Atomic structure
  2. Volumetric analysis
  3. Organic chemistry
  4. Water chemistry
  5. Reaction mechanisms.

There also is an option to be taken as part of the course which involves the study of atmospheric and industrial chemistry or the study of materials and electrochemistry.

Experimental investigations are an essential part of the leaving certificate course. Each student must complete at least 28 experiments over the duration of the course.

Experimental work is examined as part of the leaving cert exam and forms the basis for a minimum of three questions on the exam paper.

Exam Structure header image

The leaving cert exam is three hours in duration. Each candidate must answer at least two questions from Section A (experimental section) and a maximum of six questions from Section B.

There are eleven questions in total on the exam paper, each carrying 50 marks.

There is no element of continuous assessment but experimental copies must be available for inspection by the State Examinations Commission. Students taking chemistry have to memorize the chemical components of a series of prescribed experiments. They will need to present the elements of four such experiments in their exam.
