The Leaving Cert Is Changing, and Students Need to Know What That Actually Means

By Jane, Guidance Counsellor

Senior Cycle Redevelopment explained: which subjects change when, what the new assessment structures mean, and the questions every student should be asking.

If you are a parent, student or teacher involved in the Leaving Certificate, you have probably heard the phrase "Senior Cycle Redevelopment" quite a lot recently.

But what does it actually mean?

Because from talking to students, I think there is still a lot of confusion.

The Leaving Cert isn't simply being replaced overnight.

The changes are being introduced gradually, with different subjects moving to new specifications and assessment structures at different times.

One of the biggest changes is the increased role of assessment outside the traditional final written examination.

The new Senior Cycle is designed to place more emphasis on things like project work, practical work, oral assessment and other forms of assessment alongside the final examination.

For some subjects, these changes are already being introduced.

For others, they are still coming.

The Department of Education's current rollout means that students starting fifth year in 2026 will see Tranche 2 subjects introduced, including Construction Studies, Engineering, Geography, LCVP and Physical Education. English and Accounting, which were originally expected in this tranche, have been delayed by at least a year.

Then in 2027, Tranche 3 subjects are scheduled to be introduced, including Agricultural Science, Computer Science, DCG, History, Home Economics, Mathematics, Music, Physics and Chemistry.

That's a lot of change.

And I actually think the biggest issue isn't necessarily whether the new system is good or bad.

It's whether students understand what is changing.

Students need to know:

What percentage is the final exam?

What percentage is coursework or additional assessment?

What does the project actually involve?

When is it completed?

Who assesses it?

How will it affect their workload?

Will it affect how they choose their subjects?

These are all perfectly reasonable questions.

And they are especially important because the Leaving Cert isn't just an exam.

For most students, it is also connected to the CAO, so anything that changes how students are assessed can feel quite significant.

The Department of Education has also confirmed that the assessment adjustments introduced in recent years are being gradually phased out as the new curricula and examination formats are introduced.

So I think the message to students should be simple.

Don't panic.

But don't ignore the changes either.

If you're entering senior cycle, make sure you understand what applies to your subjects specifically.

And if you're unsure, ask your teachers and guidance counsellor.

There is no benefit to finding out how your assessment works two weeks before the deadline.

The Leaving Cert is changing.

Our job now is to make sure students aren't left trying to figure out those changes on their own.
