Is changing from HL to SL free?

Not necessarily, because a school's approval process does not automatically involve a charge. However, you should not assume that an HL-to-SL move is free at every school. Ask whether there is an administration charge or an examination-entry consequence. You must also retain at least three HL subjects for the normal diploma combination. Obtain written confirmation of both the approved levels and any cost before changing classes.

How late can I change an IB subject in DP1?

There is no single school subject-change deadline that applies to all DP1 students. Your school sets its own deadline based on its teaching arrangements and approval process. It may distinguish between changing subjects and changing levels within a subject. An examination-registration deadline is not the same as permission to join a different class. Ask your coordinator for the deadline that applies specifically to your proposed change.

Can my school refuse an IB subject change?

Yes, a change can be refused even if you are willing to pay any associated costs. The new class may be full or clash with another required subject. Teachers may also judge that the missed work cannot realistically be recovered. Another problem is a proposed combination that does not meet diploma requirements. Ask whether a different level or another available subject would address your concern.

Does the IB itself charge for every subject change?

An early school timetable adjustment is different from changing an examination registration. Do not assume that every classroom switch creates an IB charge. If an examination entry must be amended, the coordinator needs to check the applicable session procedures and fees. Your school should explain whether any quoted amount comes from the IB or its own policy. This article does not provide a verified May 2028 amendment tariff.

Does ESS count as both a Group 3 and Group 4 subject?

ESS can satisfy the subject-group requirements for both individuals and societies and sciences. However, it is still only one of your six diploma subjects. This flexibility can create room for another permitted subject in your combination. ESS is now offered by the IB at both SL and HL, although your school may not teach both. Ask your coordinator to check the entire proposed combination before dropping another science or humanities course.

How should I catch up after an approved DP1 switch?

Start by asking the new teacher which topics and assessed skills you have missed. Separate essential foundations from material that can wait until later in the term. Agree manageable weekly tasks alongside your current classwork. Use short practice sets to check understanding rather than measuring progress only by hours spent. Review the plan with your teacher so that mistakes do not become permanent gaps.

For M28 students: IB exams in May 2028, started DP1 in August 2026.

There is no single fee to change IB subject that applies to every DP1 student: whether you pay depends on your school's policy and whether examination-registration changes are involved. Ask your DP coordinator to confirm any charge before you agree to the switch.

An early IB subject change is a school-approved academic decision, not simply a payment transaction. This guide explains possible costs, who approves a change, and how to protect your diploma combination before moving subjects or levels.

When could a fee to change IB subject apply?

Separate the cost of changing classes from the cost of changing an examination entry. These are different processes, even when your school handles both.

Situation	What to check
Early DP1 subject or level change	Whether the school charges an administration fee or allows changes without charge
New course materials	Whether you need replacement textbooks, equipment or a different digital resource
A change after examination registration	Whether an IB registration amendment or late charge applies under the procedures for your session
Leaving a separately paid course	Whether an external provider's cancellation or refund terms apply

These are possible costs, not charges every student must pay. A school might approve a change without an administration fee while still requiring you to obtain the new textbook.

There is no verified May 2028 fee amount provided here. If your school quotes a charge, ask whether it is a school fee, a materials cost or an IB examination-registration charge, and request the amount and refund conditions in writing.

Who approves a DP1 switch, and when?

Your school approves subject and level changes and sets its own deadlines. The DP coordinator will usually need to consider teacher advice, class capacity, timetable compatibility and whether you can catch up. A subject appearing in the IB curriculum does not mean your school offers it or has a place available.

Do not assume that another school's change window applies to you. Nor should you treat a later examination-registration deadline as permission to switch classes until that date: your school's academic deadline can be much earlier.

For a new DP1 student, raising the issue promptly gives teachers more opportunity to assess the practical consequences. Continue attending your current lessons until the school confirms the change.

Check that your new combination meets diploma rules

The official IB Diploma Programme curriculum overview is the starting point for checking subject choices. In the usual six-subject diploma structure, students cover Groups 1-5 and take an arts subject or an allowed alternative.

Group	Subject area
Group 1	Studies in language and literature
Group 2	Language acquisition
Group 3	Individuals and societies
Group 4	Sciences
Group 5	Mathematics
Group 6	The arts, or an allowed replacement subject

The general rule is one subject from each of Groups 1-5, with permitted arrangements such as studying two Group 1 languages instead of a Group 2 language. The sixth subject can be an arts course or an additional permitted language, individuals and societies, or science course. Have your coordinator check the complete combination rather than judging one change in isolation.

Keep at least three HL subjects

The IB requires three or four higher level subjects, with the remaining subjects at standard level. If you have three HLs and move one to SL, you cannot simply finish with two HLs in a normal diploma combination. You would need another approved adjustment.

HL and SL also differ in scope, so moving up is not just changing the label on your timetable. Ask what additional content, skills and assessment preparation you have missed.

ESS can satisfy Groups 3 and 4

Environmental systems and societies (ESS) is interdisciplinary and can satisfy both Group 3 and Group 4 requirements. It remains one subject, not two, so you still need six subjects overall.

The IB's current ESS course information confirms that it is offered at both SL and HL. Advice describing ESS as SL-only is outdated for this cohort. Your school may nevertheless offer only one level, so confirm local availability.

Decide whether changing is academically sensible

A difficult opening topic does not necessarily mean you chose the wrong subject. Before requesting a switch, distinguish between a temporary adjustment problem and a sustained mismatch in content, assessment style or future requirements.

Ask the prospective teacher for the topics already covered and an example of normal classwork. Browse the relevant course through RevisionDojo's IB subject resources, then compare what you would actually study rather than relying on a subject's reputation for being easier.

For example, inspect Biology practice questions or Digital Society practice questions if either is a realistic option. Early practice should identify unfamiliar skills, not predict your final grade.

Also check university prerequisites before dropping a subject or moving it to SL. A combination can satisfy IB diploma rules but still fail the entry requirements of a particular degree.

What to ask your DP coordinator

Take your current and proposed six-subject lists, including levels, to the conversation. Ask:

What is our deadline for subject changes and for HL/SL changes?
Is there space in the class, and does it fit my timetable?
Does the proposed combination meet diploma requirements?
Is there any fee, materials cost or examination-registration consequence?
What work must I catch up on, and by when?

A useful message is: “I would like to discuss changing from [subject and level] to [subject and level]. Could you confirm the deadline, timetable availability, approval process and any fees, and help me check my full diploma combination?”

After approval, agree a short catch-up plan with the new teacher. List missed topics, required tasks and a review date. The approach in RevisionDojo's guide to using an IB question bank can help turn that list into focused practice rather than indiscriminate revision.

Conclusion

A DP1 switch may be possible without a change fee, but neither the cost nor approval is universal. Your school must confirm its deadline, timetable availability and charges, while your new combination must preserve diploma requirements and relevant university options.

Next step: create a free RevisionDojo account, check the free-plan features, and use your approved subject's Questionbank to plan one missed topic at a time and track completed practice.
