The qualification

International Baccalaureate Diploma Programme Physics

IB DP Physics develops an understanding of the fundamental concepts and principles of physics through five topics (space/time/motion, particulate nature of matter, wave behaviour, fields, and nuclear/quantum physics), combining theory with a self-directed scientific investigation, at Standard Level (SL) and Higher Level (HL). — International Baccalaureate, official syllabus page

First assessments 2025. This record and its matching assessment record are sourced from the full subject guide (physics-guide.pdf), originally accessed under a 2026-08-22 owner licensing confirmation, cross-verified against a current (Aug 2026) published school IB Physics resource for the exact SL/HL paper mark totals -- see the matching assessment record's own notes for the full sourcing chain. Owner decision 2026-09-05 retired that licensing framing -- no formal IB license is claimed or required. Five topics (A-E, with HL-only sub-topics within several) plus an internal assessment (individual scientific investigation).

Specifications change between examination series. Always confirm the current syllabus and assessment structure on the International Baccalaureate syllabus page for your examination year.

Source: official International Baccalaureate specification, verified 2026-08-28. This record is sourced from the full subject guide (physics-guide.pdf), originally accessed under a 2026-08-22 owner licensing confirmation. The guide's own 'Assessment outline -- SL/HL' tables (pages 62-63 of 65) could not be fully extracted through available fetch tooling in this session -- two independent mirrors of the identical PDF (ibo.org direct and a bradfieldcollege.org.uk copy) both truncated at the same point, before reaching the assessment section, which is a tool-side extraction cap rather than a source problem (confirmed by matching truncation length on unrelated hosts). The component structure, durations and weightings below are taken from that guide's earlier, successfully-extracted 'Curriculum model overview' and assessment-summary prose, and the exact mark totals were cross-verified against a current (checked 2026-08-28), actively-maintained school IB Physics resource (Concordian International School Thailand LibGuide, 'External assessment' and 'Internal assessment' pages) that transcribes the same official table in detail; both sources agree. SL: Paper 1 (multiple-choice with short data-based questions, 90min, 45 marks, 36%, calculator and data booklet permitted); Paper 2 (short-and-extended-response questions, 90min, 50 marks, 44%, calculator and data booklet permitted); Internal Assessment (individual scientific investigation marked against 4 criteria worth 6 marks each = 24 marks, no fixed sitting duration, 20%, internally assessed and externally moderated). HL sits the same two paper types at greater length and mark total (Paper 1: 120min/60 marks/36%; Paper 2: 150min/90 marks/44%) plus the same-weighted internal-assessment investigation (24 marks, 20%). 'DP Physics' is used as this record's own `code`. First assessed 2025 per the guide's own title page -- the most recently first-examined DP science course. This is one of only two IB DP subjects (with Economics) originally sourced from the full guide under that 2026-08-22 confirmation; a separate owner decision, also 2026-09-05, retired the licensing framing entirely -- no formal IB license is claimed or required. See the Economics DP record above for how the licensing-scope limitation was, independently, also narrowed once IB's own freely public specimen exam papers were confirmed sufficient as a primary source for other DP subjects. The site's 5 IB Middle Years Programme subjects are a separate case, resolved 2026-09-04: MYP's own assessment structure is genuinely criterion-referenced (no fixed exam papers with raw marks for most students), so the freely public subject briefs ARE sufficient to model it correctly -- see the 5 IB Middle Years Programme records below.
