Physics in US secondary school. Middle school (Grades 6–8) and high school physical science follow the Next Generation Science Standards (NGSS); the advanced tier is AP Physics — the College Board courses that colleges give credit for, and the closest US equivalent to A-level.
NGSS writes high-school physical science by core idea rather than by year, so the high-school courses below are organized that way (forces, energy, waves, matter & nuclear), each gathering the standards from across Grades 9–12.
