How to Start Your CAO Application: A Beginner’s Guide

Starting your CAO (Central Applications Office) application can feel overwhelming, especially if it’s your first time applying to college. But with a clear plan and the right resources, the process can be straightforward and stress-free. This guide will walk you through the key steps to get started.

1. Understand What the CAO Is

The CAO is the system used to apply to most undergraduate courses in Ireland, including universities, institutes of technology, and some private colleges. Your CAO application allows you to list your course preferences in order of priority, which the admissions system uses to allocate places based on points, entry requirements, and availability.

2. Research Courses and Colleges

Before starting your application, spend time exploring your options. Consider:

• Course content and modules

• College location and facilities

• Entry requirements (including Leaving Cert subjects and points)

• Career opportunities after graduation

Use Whichcollege.ie to browse thousands of full-time, part-time, and PLC courses. The site allows you to filter by subject, level, location, and type of study, helping you find courses that match your interests and goals.

3. Create a CAO Account

Once you know which courses you want to apply for, visit the CAO website and register for a new account. Make sure you have:

• Personal details (name, date of birth, PPS number)

• Educational information (Leaving Cert or equivalent results)

• Payment method for the application fee

Keep your login details safe, as you will need them to track your application and make changes before the closing date.

4. Choose Your Course Preferences

You can list up to 10 Level 8 courses (honours degree) and 10 Level 7/6 courses (ordinary degree, higher certificate) on your main application. Remember:

• List courses in order of preference

• Be realistic about points requirements

• Include a mix of “dream” and “safe” options

Whichcollege.ie is a great tool to compare course content and requirements to help you make informed choices.

5. Submit Your Application

Before submitting, double-check:

• Your personal and educational details are accurate

• Your course preferences are correct

• You’ve paid the application fee

The CAO application window typically opens in November and closes in February for most applicants. Late applications may be accepted but can incur extra fees.

6. After Submitting

Once your application is submitted, keep track of:

• Change of mind period: usually in May–July, where you can reorder your preferences

• Offer rounds: usually in August, when places are allocated based on points

It’s also a good time to explore additional preparatory courses, bridging programmes, or part-time options on Whichcollege.ie to strengthen your academic profile.

Key Tips for Success

• Start early to give yourself plenty of time to research

• Keep a checklist to avoid missing important deadlines

• Use Whichcollege.ie to explore alternative courses if your first choices don’t work out

• Don’t hesitate to seek advice from teachers, guidance counsellors, or college advisors

Starting your CAO application doesn’t have to be stressful. With careful planning, research, and support, you can approach it confidently and make the best choices for your future.
