Choosing Your Highers After National 5: The S5 Subject Guide

The move from National 5 to Higher is the most important academic step in Scottish secondary school. It is also the one that catches the most families off guard — because the choices are made months before N5 results are published. Here is how the process works, what decisions you will face, and how to make them well.

When choices happen: the S4 timeline

Subject choices for S5 Highers are made in January or February of S4, as part of your school's senior phase options process. This is months before N5 results are published in August.

That timing matters. When you sit down to choose your Highers, your N5 work is still in progress. You are choosing based on how your studies are going, your teacher's assessment of your progress, and your longer-term plans — not on confirmed results.

A Scottish Government survey carried out in 2019 found that class teachers are the most commonly cited influence on course choice decisions for Scottish pupils. Subject teachers provide written recommendations on your readiness for Higher, and your guidance or pupil support teacher will conduct an individual interview with you in S4 to talk through your options. Both of those conversations are worth taking seriously.

Curriculum for Excellence places an explicit emphasis on personalisation and choice — you have a genuine voice in this process. Use it. Come to your guidance interview with a clear view of what you want, not just a blank sheet waiting to be filled.

How many Highers to take

Most S5 pupils take four or five Highers. Five is the conventional target for university entry, and it is the number that university admissions staff generally expect to see by the end of S5.

Taking fewer than four Highers is possible but limits your options significantly for competitive courses. Taking six is also possible, but the risk of spreading yourself too thin is real — five Highers studied well outperforms six studied poorly in almost every scenario.

For competitive university entry — Medicine, Law at Edinburgh, and Computer Science at Edinburgh, for example — five Highers at high grades by the end of S5 is expected. These are courses where spreading Highers across S5 and S6 is viewed less favourably by admissions staff. If any of those routes are in your sights, five in S5 is the goal.

For the majority of university courses, a mix of S5 and S6 Highers is perfectly acceptable. Many pupils take three or four in S5, add one or two more in S6, and apply to university with a combined portfolio.

Which subjects to carry forward

Pupils typically carry four or five N5 subjects forward into Higher. There is no requirement to turn every N5 into a Higher — that is not what S5 is for. Breadth in S4 narrows to depth in S5.

When deciding which subjects to move forward, ask three questions:

1. Are you genuinely interested in the subject? Motivation drives grades at Higher more than at any earlier level.
2. Does this subject keep doors open for what you want to do after school? Chemistry is non-negotiable for Medicine. English is essential for most university courses. History is useful for Law.
3. What is your teacher telling you? If a subject teacher is recommending against Higher in their subject, that advice is usually based on real evidence of how you are performing at N5.

Dropping a subject you passed at N5 is completely normal and healthy. You are not abandoning it — you are making a deliberate choice to focus elsewhere. The subjects you keep should be the ones you want to invest serious time in.

Crashing a Higher: what it means and why it's risky

"Crashing" a Higher means taking a Higher in a subject you did not sit at National 5 level. Qualifications Scotland (formerly SQA) technically permits this, but it is school-managed — your head teacher and guidance staff decide whether it is allowed in practice.

The pass rate for pupils crashing a Higher is generally poor. Higher-level content assumes National 5 knowledge as a foundation. Without that groundwork, you are covering two years of material in one.

The main exceptions are pupils who have very strong background knowledge from outside school — for example, a first-language speaker of a Modern Language, or a pupil who has studied a subject independently to a high level. If you believe you have that kind of background in a subject, discuss it honestly with the subject teacher. They will tell you whether the plan is realistic.

Do not crash a Higher simply because it sounds useful or looks impressive. A failed or very weak Higher grade is worse than no Higher in that subject at all.

The August review window

N5 results are published in August — after your Higher choices were made in January or February. This creates a window where last-minute adjustments are sometimes necessary.

Most schools hold a formal August review in the first week back. This is your opportunity to meet with your guidance teacher and request a level change if your results came in differently from expectations:

• If your N5 results were lower than predicted, you may want to move from Higher to an N5 resit.
• If your results were better than expected — an A in a subject you were uncertain about — you may be able to move up into a Higher you had not originally planned to take.

These changes become increasingly difficult after that first week. Once timetabling is confirmed and teaching begins in earnest, moving between classes disrupts both you and the class you are joining. Act quickly if you need to make a change, and speak directly to your guidance teacher rather than waiting to see how things go.

Who guides you — and what their advice is worth

Two key people lead your S5 subject choice conversations:

Your guidance or pupil support teacher coordinates the overall process. They know your academic profile across all subjects, your attendance record, and your broader plans for after school. Their interview with you in S4 is a chance to think out loud with someone who has a full picture of where you are.

Your subject teachers provide written recommendations on your readiness for Higher in their specific subject. A teacher who says you are ready for Higher has watched you work at N5 level and believes you can handle the step up. A teacher who expresses reservations is not writing you off — they are flagging a genuine risk worth talking through.

Your own view matters too. Qualifications Scotland's framework gives you a voice in this decision, and the choice is ultimately yours within the options your school can offer.

Tips for parents

Supporting your child through Higher choices does not mean making the decisions for them. The most useful things you can do are:

• Attend the school options evening — every secondary school runs one, and subject teachers are present to answer specific questions about what their Higher involves.
• Ask about prerequisites, not just preferences — find out which specific Higher subjects are required for the university courses your child is considering, before the S4 subject choice interview takes place.
• Read the teacher recommendations carefully — if multiple subject teachers flag concerns about the same subject, that pattern is worth a direct conversation with the guidance teacher.
• Let your child own the choice — they are the one sitting the exams and doing the work. A subject chosen under parental pressure rarely ends well for either of you.
