01
Prepare before the appointment
Write one page: what you notice, since when, in which settings, and what it stops your child doing. Add a teacher's note or a copy of the school's SEN record if you have one.
Standard questionnaires such as Conners or SDQ are often requested from both home and school. Asking the school to complete theirs early saves weeks.
02
Who assesses children
A community paediatrician, child psychiatrist or specialist neurodevelopmental team, drawing on parent interview, school information and direct observation.
Assessment also looks for co-occurring conditions — autism, learning difficulties, anxiety, sleep disorders — because these change what support helps.
03
While you wait
Push on school support in parallel: it does not depend on the assessment. Keep the diary going, and keep copies of every letter.
If the wait is long, ask what interim support the service offers and whether a parent programme is available locally.
