For M28 students: IB exams in May 2028, after starting DP1 in August 2026.
Yes, you can ask for an IB retest, but your school and teacher decide whether one is available. For an ordinary DP1 classroom test, the IB does not operate a universal retest policy, so you are not automatically entitled to another attempt.
Students often use “IB retest” to describe different processes. A classroom reassessment in DP1, an official examination retake after final results, and a request for an official remark have separate rules.
Is a DP1 retest controlled by the IB or your school?
Most DP1 tests are created, administered, and marked by your school. These may include topic tests, essays, practical tests, quizzes, unit examinations, and end-of-term assessments.
Your school determines whether these assessments can be retaken. Its policy may permit reassessment after an approved absence, impose conditions, cap the replacement grade, record both attempts, or prohibit retesting. Departments may also have rules within the wider school assessment policy.
The IB does not require schools to provide another attempt at every classroom assessment. Saying that the IB permits official examination retakes does not establish a right to retake a first-term DP1 test.
Before asking, check:
- Your school assessment or grading policy
- Your course handbook and assessment instructions
- Department rules about absence and reassessment
- Guidance from your teacher or DP coordinator
If the written policy is unclear, request clarification rather than claiming that the grade is unfair.
What do your first IB grades mean?
Your first IB grades may feel unusually low because IB-style markschemes reward precise evidence of achievement. A long answer can lose marks if it lacks subject terminology, analysis, working, evaluation, evidence, or direct engagement with the command term.
Most early IB grades in DP1 are school-reported indicators, not final grades awarded by the IB. They still matter because teachers use assessment evidence to monitor progress, write reports, identify support needs, and eventually form predicted grades according to school procedures.
One disappointing result is not a reliable forecast of your May 2028 outcome. Treat it as evidence about your current knowledge and skills. Ask what the assessment shows you need to learn, not only how to remove the mark.
RevisionDojo’s guides to starting DP1 strongly and the first month of the IB Diploma explain how to respond to early gaps constructively.
When is asking for an IB retest reasonable?
A polite request is particularly reasonable when an identifiable circumstance affected the validity of the result. Examples include:
- An approved or documented absence
- Illness or an emergency during the assessment
- A technical problem during a digital test
- An administrative error in the paper or conditions
- A school policy that explicitly permits reassessment
- An invitation from the teacher to demonstrate improvement
You may ask after ordinary underperformance, but disliking the mark does not create an entitlement to another attempt. Retesting changes the evidence used for grading, so teachers must consider consistency and fairness across the class.
Some schools require corrections, support sessions, or additional practice before a retest. These are local conditions, not universal IB rules.
How to ask your teacher politely
Review the paper before making your request and identify why marks were lost. This shows that your priority is learning rather than negotiating for points.
A concise request could say:
I reviewed my test and noticed that I struggled with the evaluation questions and did not use evidence consistently. Does our assessment policy allow a retest or another way to demonstrate improvement? I understand if the original grade must remain, but I would appreciate guidance about what to practise.
Include three elements:
- Ownership: Acknowledge your preparation or performance honestly.
- Evidence: Identify the concepts or assessment skills that caused difficulty.
- A practical request: Ask about the policy, corrections, a retest, or another permitted task.
Do not demand a retest, compare yourself with classmates, or argue that effort alone deserves a higher grade. Grades normally represent demonstrated achievement against assessment expectations.
What if the teacher says no?
A refusal means the original result remains under the school’s policy, not that improvement is impossible. Ask which weaknesses cost the most marks, whether you misunderstood content or command terms, and whether you may complete corrections for feedback.
Create an error log containing the question topic, reason for the lost mark, and a rule for future responses. For example: “For evaluate questions, discuss supported strengths and limitations before reaching a justified conclusion.”
Use targeted practice instead of repeating an entire unit. Revision strategies that avoid burnout can help you rebuild missing knowledge, while the guide to learning from difficult IB papers shows how to turn errors into specific revision tasks.
If you believe the policy was applied incorrectly, speak calmly with the teacher first. If the procedural issue remains unresolved, consult the head of department or DP coordinator through the school’s normal process.
Classroom retests, official retakes, and remarks
These terms are not interchangeable.
| Process | When it happens | Who controls it? | Purpose |
|---|---|---|---|
| DP1 classroom retest | During the school course | School or teacher | Reassesses learning under local policy |
| Official IB examination retake | After an IB examination session | IB procedures and a registering IB World School | Allows a candidate to sit an examination again |
| Enquiry upon results | After official results | Requested through the DP coordinator | Provides an available results service, potentially including re-marking |
The IB states that candidates may retake examinations, but schools have their own admissions policies and are not obliged to accept retake candidates. The IB assessment and results FAQ explains that an enquiry upon results must be discussed with and submitted through the DP coordinator.
Neither process applies to an ordinary DP1 test. Official retakes concern candidates who have completed an IB examination session. RevisionDojo’s IB Diploma retake overview explains this later process.
Conclusion
You may ask for an IB retest, but DP1 classroom reassessment is determined by school policy rather than guaranteed by the IB. Ask respectfully, show that you have analysed your mistakes, and accept that the original result may remain.
