IB Social and Cultural Anthropology SL: the mark you need, paper by paper

Session

Grade

In May 2025 TZ3 a 7 overall started at 81 out of 100 scaled marks. On each component:

Component	Out of	Minimum for a 7	As %
Internal assessment	26	22	85%
Paper 1	30	25	83%
Paper 2	30	25	83%

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)	81	70	56	45	29	14	11
May 2021 (non-exam route)	80	66	54	41	29	13	14

What the components say about where to work

In May 2025 TZ3 a 7 needed 85% on Internal assessment and 83% on Paper 1. The component with the lower threshold is the one candidates found hard, and it is usually the one where a few marks are cheapest to gain.

Marked work (internal assessment, orals, written tasks) is assessed against criteria known in advance, so it is the part of the grade under the student’s control before the exam. Which written paper has the lowest threshold changes from session to session, so a past paper should be marked against the boundaries of its own session, not against the latest one.

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 80% in TZ2 and at 81% in TZ3.

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.

The gap between a 6 and a 7

In Social and Cultural Anthropology SL the 6 sits on average 12.8 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 81% or more on full mocks under exam conditions has a 7 in every session on record. A student at 73% has a 7 only on the hardest paper, and should plan for the 6 to 7 gap rather than assume it.

Sources

All 8 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 Social and Cultural Anthropology SL?

81% of the scaled marks in May 2025 TZ3. Over 8 sessions since May 2017 the 7 has started between 73% and 81%, 78.6% 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 Social and Cultural Anthropology SL?

Between 11 and 14 on the 100-mark scale, 12.8 on average. In May 2025 TZ3 it was 12 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.

Which component needs the highest mark for a 7 in Social and Cultural Anthropology SL?

In May 2025 TZ3 Internal assessment needed 22 out of 26 (85%) for a 7, the highest of the components, while Paper 1 needed 25 out of 30 (83%). The overall grade is what counts: a strong component carries a weaker one.

Are Social and Cultural Anthropology SL grade boundaries going up or down?

The May 7 moved from 80% in May 2024 to 81% in May 2025 TZ3. A move of a few points between years is normal and reflects how hard that paper was, not a change in the standard.

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 8 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.
