Navigating the Central Applications Office (CAO) can feel like a daunting task for Leaving Certificate students, mature applicants, and international students alike. From calculating your final score to understanding the nuances of the Change of Mind window, mastering the CAO system is the first critical step toward securing your place in an Irish university or college.

Whether you are aiming for a highly competitive medical degree, exploring National Tertiary Office courses, or simply trying to figure out how a CAO points calculator works, this comprehensive guide covers everything you need to know about the CAO process, alternative degree routes, and how to maximize your chances of getting your first-choice course.

1. Getting Started: Navigating the CAO System

The CAO is the centralized hub that processes applications for undergraduate courses in Irish Higher Education Institutions (HEIs).

Creating Your Account and Initial Setup

Your journey begins at the CAO login portal. To start your application, you must register your personal details, create a password, and pay the application fee. It is highly recommended to register early to take advantage of discounted rates.

How much is the CAO application fee?

The standard application fee is typically €45. However, if you apply early (usually before January 20th), you can avail of the discounted rate of €30. Late applications incur a higher fee of €60.

Note: If you make a mistake or decide to withdraw your application entirely before the early May deadline, you might wonder how to get a refund on the CAO fee. Refunds are only issued in very specific, limited circumstances (such as accidental duplicate applications), and you must contact the CAO directly via your portal to request one.

Structuring Your Application

When filling out your preferences, a common question is: How many choices do you get on the CAO form?

You get a total of 20 choices, split across two distinct lists:

  • 10 choices for Level 8 (Honours Bachelor Degrees)
  • 10 choices for Level 7/6 (Ordinary Bachelor Degrees and Higher Certificates)

Can you mix Level 7 and Level 8 choices on the CAO?

No, the lists are kept entirely separate. However, they operate independently. This means you can apply for 10 Level 8 courses AND 10 Level 7/6 courses. On offer day, you may receive two offers simultaneously—one from your Level 8 list and one from your Level 7/6 list. You can only accept one.

2. Demystifying the Points System

Your Leaving Certificate results dictate your final score, which universities use to allocate places. To figure out where you stand, most students use a CAO points calculator. Points are calculated based on your six best subjects in one sitting of the Leaving Certificate.

The Basic Calculation

Points are awarded based on the grade you achieve. An H1 (90-100% at Higher Level) yields 100 points, while an O1 (90-100% at Ordinary Level) yields 56 points. Bonus points (25) are awarded for a passing grade (H6 or above) in Higher Level Mathematics.

Factoring in the LCVP

Many students take the Leaving Certificate Vocational Programme (LCVP) as an additional module. How to calculate CAO points with LCVP is a common point of confusion. The LCVP is graded as Distinction (66 points), Merit (46 points), or Pass (28 points). If your LCVP score is higher than your lowest score among your top six subjects, it can replace that sixth subject in your total points calculation.

Target Points for Popular Courses

Points fluctuate annually based on supply and demand, but certain competitive fields remain historically high:

  • How many points for primary teaching? Primary education (B.Ed) courses typically require between 480 and 520 points, alongside specific minimum grade requirements in Leaving Cert Irish.
  • How many CAO points for computer science? Depending on the university, Computer Science ranges from 350 points in regional technical universities to 550+ points in institutions like UCD or Trinity College Dublin.

What Happens in a Tie?

If a course cutoff is exactly 450 points, and you achieve exactly 450 points, you might notice an asterisk (*) next to the points in the CAO handbook. How does the CAO points system work for random selection?

When more applicants have the exact cutoff score than there are places remaining, the CAO assigns a random number to every applicant. Those with the highest randomly generated numbers are offered the remaining places.

3. Critical Deadlines and The Change of Mind Window

The CAO operates on a strict timeline. Missing a deadline can severely limit your educational options for the year.

The Standard and Late Deadlines

The normal application deadline is February 1st. If you miss this, you must rely on the late application window. What is the late CAO application deadline? The late facility opens in early March and closes strictly on May 1st at 5:00 PM.

The Change of Mind Facility

Perhaps the most crucial period of the CAO cycle is the Change of Mind window. Opening in early May, this facility allows you to add, remove, or completely reorder your course choices for free.

  • CAO change of mind deadline: The absolute final cutoff for changing your course preferences is July 1st at 5:00 PM.

Can you change CAO courses after the deadline?

Generally, no. Once the July 1st deadline passes, your course choices are locked in. The system strictly adheres to your order of preference.

How to apply for an exceptionally late CAO change of mind:

In incredibly rare circumstances—usually relating to a severe, documented medical emergency or a sudden, catastrophic change in personal circumstances—you can contact the CAO directly. However, “exceptionally late” changes are almost never granted for simple indecision.

4. Navigating Offers and Available Places

August brings Leaving Cert Results Day, quickly followed by Round 1 of CAO offers.

Managing Your Offers

When offers are issued, you must act quickly. If you receive an offer for your 2nd preference on your Level 8 list, preferences 3 through 10 are permanently deleted from your profile.

  • Can I accept a lower CAO preference later? No. You can never move down your list. However, you can move up. If you accept your 2nd preference in Round 1, you may still be offered your 1st preference in Round 2 if points drop.
  • How to defer a CAO college place: If you receive an offer but wish to take a gap year, do not accept the offer on the CAO login portal. Instead, immediately contact the admissions office of the specific university in writing (or via email) requesting a deferral. If granted, they will instruct the CAO to hold your place for the following year.

The Available Places Facility

What happens if I don’t get any CAO offers?

If Round 1 and Round 2 pass without an offer, do not panic. You have access to the CAO available places listings. This is a portal where universities advertise courses that have not been completely filled.

  • CAO available places entry requirements: To apply for an available place, you must still meet the minimum matriculation requirements for that specific course (e.g., passing Maths or English), but you do not need to meet the original points cutoff. Anyone can add an available place to their CAO application, even if they didn’t apply for it originally.

5. Alternative Degree Routes (Outside the Standard CAO)

The traditional CAO points race is not the only way to earn a Level 8 degree. The Irish education landscape has evolved significantly to include direct-entry, tertiary, and international pathways.

The National Tertiary Office

A massive shift in Irish education is the introduction of National Tertiary Office courses. These programs allow students to begin their degree in a Further Education (FET) college and automatically transition to a Higher Education university to complete their Level 8 degree—without relying on Leaving Cert points.

  • Tertiary degree nursing Ireland: You can now begin a nursing degree through a local FET center and seamlessly progress to a partnered university to finish your clinicals and graduate with a BSc in Nursing.
  • Tertiary degree business courses Ireland: Similar pathways exist for business, engineering, and IT, providing a stress-free alternative to the points race.

Direct Entry vs. CAO

You may encounter degrees outside the CAO system, particularly from private colleges (like Griffith College or DBS) or specialized international programs.

  • Difference between direct entry and CAO courses: Direct entry means you apply straight through the college’s own website, completely bypassing the CAO points system. While these are often fee-paying private programs, they provide an excellent backup option.

Non-Standard Applications

  • Mature student CAO applications: If you are over 23 years of age by January 1st of the year of entry, you are classified as a mature student. Your application is generally assessed on your life experience, work history, and an interview or aptitude test (like the MSAP), rather than Leaving Cert points. Mature applicants must apply by the February 1st deadline.
  • How to link your UK UCAS application to the Irish CAO: If you are a Northern Irish or UK student applying through both UCAS and the CAO, you must ensure your A-Level results are translated into the CAO points system. While the systems don’t digitally “link,” you will need to submit your certified A-Level statements to the CAO via post before the summer deadlines to ensure your points are calculated accurately.

Summary and Next Steps

Securing your ideal college place in Ireland requires strategic planning. By understanding how a CAO points calculator evaluates your grades, strictly observing the CAO change of mind deadline, and keeping your mind open to National Tertiary Office courses or CAO available places listings, you can navigate the system with confidence.

Take the time to explore each of these topics deeply. Map out your top 20 choices, prepare your fallback options, and ensure your CAO login portal details are secure ahead of the fast-approaching deadlines.
