IB Diploma Programme Physics Standard Level is a two-year group-4 science in the International Baccalaureate Diploma. The 2025 guide (first assessment May 2025) replaces the old core-plus-options model with five interconnected themes studied by all students: A – Space, time and motion; B – The particulate nature of matter; C – Wave behaviour; D – Fields; and E – Nuclear and quantum physics. SL covers the standard-level content of each theme alongside a 40-hour practical programme. Assessment is two external examination papers plus an internally assessed scientific investigation, graded on the IB 1-7 scale.
