Screening versus Assessment

What is ADHD screening?

ADHD screening aims to identify individuals who may show signs of ADHD and decide whether a more detailed evaluation is needed. It typically involves questionnaires, interviews, and behavioural observations.

Screening can't give a diagnosis — it just helps professionals like psychologists or paediatricians decide if it's worth looking deeper.

Screening and assessment

What is an ADHD assessment?

An ADHD assessment, on the other hand, is a thorough process done by a trained professional. It includes detailed interviews, observations, working directly with the child, and using standardised tests and checklists. The aim of an assessment is to find out whether a child meets the criteria for a diagnosis of ADHD. If they do, it leads to a formal diagnosis along with a detailed report full of recommendations, support strategies, and ideas to help the child thrive.
