CAO order of preference, explained with an offer-day example

Meet Niamh and her four choices

Niamh is interested in business and law. She has compared first-year modules, assessment, travel and entry requirements, and she has four Level 8 courses she would honestly be happy to study. She also knows that last year’s points are only a guide. She writes the courses in this order:

Now change one detail: suppose Niamh moved Commerce to number 1 because she thought she had a better chance of getting it. If she received that Commerce offer, she would not then receive an offer for Law and Business or Law lower down the same Level 8 list. That is why “play it safe by putting the easier course first” can work against what you actually want. The official CAO 2027 handbook explains this in its Order of Preference and Offer Stage sections.

What “preference” means on offer day

CAO’s ranking rule is not a prediction of your exam results. It is an instruction about which offer you would rather receive. Within each list, a course in position 1 is preferred to every course below it. If you are eligible for several courses and an offer can be made for more than one, the higher preference takes priority.

In the example, Niamh’s place on the Commerce course does not mean College A and College B were pointless choices. It means those options were not offered to her in that round. If a higher-preference offer becomes available later, she may receive it. Her fourth preference will not replace the third-preference offer just because it also has places.

Where two courses are genuinely close, find something concrete to break the tie: first-year compulsory modules, how you are assessed, placement, travel time, cost of living, or whether a specialist subject begins immediately. The list should reflect an informed preference, not a points ladder.

Points are only one gate

Imagine Niamh gets a points score above last year’s figure for a course, but misses a required Maths grade. She cannot treat the points score as a replacement for that subject requirement. The CAO handbook says the system first checks whether applicants meet the minimum entry requirements, then calculates points for eligible courses. Colleges may specify particular grades, subjects, tests or other conditions.

That is a crucial distinction when you use a course search tool. A filter showing courses around your estimated points is a discovery tool. It cannot certify that you are eligible or guarantee an offer. Open the current college course page and check the course-specific requirements and general matriculation rules. If a requirement is unclear, ask the college admissions office or your guidance counsellor before relying on the course as a fallback.

Previous points are useful context, but they are not a fixed entry price for 2027. Demand and the number of places may change, and ties can involve random selection. A sound shortlist includes options you genuinely want at a range of past points, while keeping the order based on preference.

Two separate lists: Level 8 and Level 7/6

This is easy to miss if you have only been looking at honours degrees. The CAO application has one Level 8 list and a separate Level 7/6 list. The 2027 handbook says you may enter up to ten choices on each; choices on one list do not change the ranking on the other. You can receive an offer from each list and then choose between them.

A Level 7 course is not automatically a worse choice. Look at what you will study, award level, progression possibilities and the particular institution. If it is a course you would seriously consider, research it with the same care as your Level 8 choices. Leaving this list empty because you only know the names of universities narrows your options unnecessarily; adding a course you would never attend is not helpful either.

Can you change your CAO course order later?

For the 2027 cycle, the CAO handbook lists a free Change of Mind period expected to open on 5 May 2027 and close on 1 July 2027 at 5pm. You can add, remove or reorder eligible course choices during that window, and the handbook advises checking both the acknowledgement email and your updated application. Always check CAO’s current handbook and important dates before acting, as dates can change.

There is an important exception: a restricted course may require a portfolio, interview or other assessment and normally cannot be introduced for the first time through the May–July Change of Mind facility. The 2027 handbook sets earlier application and amendment deadlines for these courses and describes a narrow exception for shared assessment procedures. If you are considering one, read its official entry and deadline information early; do not assume July is enough time.

Changing your mind should reflect new information. After an open day, you might learn that a compulsory module is very different from what you expected. Or you might discover that a particular journey is not realistic every week. Those are good reasons to reassess the list. A mock-exam result on its own is not a reason to put a less-preferred course above your favourite.

A five-minute list check before you submit

Use this as a small audit of your own draft; you do not need a complicated spreadsheet to get the order right.

1. Start with courses, not cut-offs.

   From CAO Finder, save courses that interest you across at least a couple of colleges or subject areas. The shortlist is for research; your final application belongs on CAO.

2. Test each pair.

   For the courses in positions 1 and 2, ask which you would attend if both were offered. Repeat down the list. If you cannot answer, compare the official modules and day-to-day practicalities.

3. Check eligibility separately.

   Record required subjects, levels, grades, tests and deadlines from the college’s current page. Mark an unanswered requirement as “check” rather than guessing.

4. Review the second list.

   Consider genuine Level 7/6 options if they interest you, and rank that list on its own merits.

5. Read it back as an offer.

   Imagine the highest option available to you on each list being offered. Would you rather have any course below it? If yes, fix the order before you submit, then check the CAO acknowledgement.

Try doing the first draft without looking at points. Afterwards, use your estimated score and last year’s figures to see whether you want to research more options—not to reorder favourites into “safe” and “risky” positions.
