What do I need

IB Design Technology SL: the mark you need, paper by paper

Session

Grade

In May 2025 TZ2 a 7 overall started at 71 out of 100 scaled marks. On each component:

Component	Out of	Minimum for a 7	As %
Internal assessment (practical work)	36	27	75%
Paper 1A (multiple choice)	30	23	77%
Paper 2	50	33	66%

Component grades come straight from the IB document for that session. The overall grade is on a 100-mark scale built from the components with the weightings in the subject guide, so it is not computed here: a strong component carries a weaker one, and the table shows how much room each one leaves.

Non-examination route, 2021 and 2022

Sessions in which schools that could not sit written examinations were graded on coursework and predicted evidence. The IB issued a separate boundaries document for that route.
Session	7	6	5	4	3	2	Gap 6 to 7
May 2022 (non-exam route)	66	53	42	32	22	10	13
May 2021 (non-exam route)	56	48	42	32	22	10	8

Timezones: the same session, different papers

In May the IB sets different papers for different parts of the world, and each gets its own boundaries. In May 2025 the 7 started at 71% in TZ2 and at 71% in TZ1.

A gap between timezones is not an advantage for one of them: the boundary follows the paper. The useful reading is the range across all timezones and sessions, which is what the first table shows.

May against November

On record the 7 in Design Technology SL has averaged 68% in May and 70% in November. The two sessions are set to the same standard; the difference is the papers, not the season.

The gap between a 6 and a 7

In Design Technology SL the 6 sits on average 10.5 marks below the 7 on the 100-mark scale. That is roughly one question answered fully instead of half-answered, or the marks lost to misread instructions across a whole paper.

Use the range, not the last session. A student scoring 75% or more on full mocks under exam conditions has a 7 in every session on record. A student at 46% has a 7 only on the hardest paper, and should plan for the 6 to 7 gap rather than assume it.

Sources

All 10 sessions were read from the grade boundaries document the IB issues to Diploma Programme coordinators after each session (one document per session; 2021 and 2022 have an examination-route and a non-examination-route document). The full dataset for every IB subject is on the grade boundaries overview, as CSV and JSON.

Frequently asked questions

What percentage do you need for a 7 in IB Design Technology SL?

69% of the scaled marks in November 2025. Over 10 sessions since May 2017 the 7 has started between 46% and 75%, 68.3% on average. There is no fixed figure: the IB sets the boundaries after each session, once the papers have been marked.

How many marks separate a 6 from a 7 in Design Technology SL?

Between 7 and 12 on the 100-mark scale, 10.5 on average. In November 2025 it was 11 marks. That is the size of one question answered fully instead of half-answered, which is why exam technique moves this grade more than new content.

Are Design Technology SL grade boundaries going up or down?

The May 7 moved from 71% in May 2024 TZ2 to 71% in May 2025 TZ2. A move of a few points between years is normal and reflects how hard that paper was, not a change in the standard.

Is November easier than May in Design Technology SL?

Not in the boundaries: the 7 has averaged 68% in May sessions and 70% in November sessions on record. The IB sets both to the same standard, so a difference of a point or two reflects the papers of those sessions, not a softer session.

Where do these numbers come from?

Every row on this page was read from the grade boundaries document the IB issues to Diploma Programme coordinators after each session, for all 10 sessions shown. The document lists, for every subject and level, the minimum raw mark for each grade on each component and the minimum scaled mark out of 100 for the overall grade.
