How people develop across a lifetime, and the four domains development is described in.

What it is
Development is usually described in stages — infancy, early childhood, adolescence, early, middle and later adulthood — across four domains: physical, intellectual, emotional and social, often abbreviated PIES.
Where it applies
GCSE and BTEC health and social care, and child development.
How it works
Development is sequential but not uniform: the order of milestones is broadly consistent, the timing varies widely between individuals, and that variation is normal.
Life events — bereavement, moving, illness, redundancy — affect development and are examined as expected or unexpected.
How to use it in your work
Use PIES as your structure for any "describe the effects of X" question. Four domains, four paragraphs.
Give age-appropriate examples with rough ages, and say that timing varies.
For life events, distinguish expected from unexpected and note that support networks change the impact.
Where to get help
Your teacher and your board's specification — these qualifications vary more between boards than the traditional GCSEs do, and much of the grade is coursework marked against stated criteria.
Revise this with a song
These are ours. We write revision songs because a lot of people remember a tune when they cannot remember a page, and because revising out loud in the kitchen beats staring at a highlighter.
