TL;DR
The 2026 SEAB Physics syllabus keeps the Planning/MMO/PDO/ACE framework (Section 4, SEAB 2026 syllabus).
Consistent moderation hinges on shared descriptors, calibration datasets, and tight apparatus management.
Use this toolkit to align department mark schemes, run moderation meetings, and keep your documentation SEC-ready as MOE/SEAB roll out the Secondary Education Certificate from 2027 (MOE press release; SEAB SEC page).

1 | Pre-moderation setup
- Share descriptors: Circulate the SEAB Planning/MMO/PDO/ACE bullet points with annotated clarifications for your school context.\
- Select baseline tasks: Choose 3–4 experiments covering mechanics, thermal, electricity, and optics. Ensure they mirror the 18 SEAB-listed tasks.\
- Prepare reference data: Collect “gold standard” tables/graphs (anonymous student samples or teacher exemplars) with known grades.\
- Log apparatus status: Note calibration dates, serial numbers, and any quirks (e.g. power supply drift) in a shared spreadsheet.
2 | Running a moderation meeting
- Anchor discussion: Start with one exemplar script per grade band (A/B/C). Highlight where Planning/MMO/PDO/ACE evidence appears.\
- Blind marking round: Have each teacher grade two new scripts independently.\
- Compare & discuss: Surface differences, referencing specific criteria (“PDO column units missing, hence deduction”).\
- Update mark scheme: Amend internal rubrics or checklist phrasing so future marking references a single source of truth.\
- Record decisions: Capture action items (e.g. “Require explicit uncertainty statement for full ACE mark”) in a moderation log.
