Our ADHD Assessments have 5-6 stages:
Stage 1. Pre-Assessment Admin. This includes a screen to check if an assessment is warranted.
Stage 2. Eight formal assessment tools/ questionnaires. Six are self-report and two are for observers: someone who currently knows you well, and someone who knew you in childhood.
Stage 3. At least two hours (to 2.5 hours) of clinical interviews with a qualified and experienced Psychologist.
Stage 4. (optional) QB Check: Recommended to clients who may have an inconclusive outcome or for clients who would like an objective assessment of their ADHD symptoms. This is a specialised QB check software and has an additional fee of £100.
Stage 5. 30-minute feedback session to discuss the findings of the assessment. If you wish to consider medication, we have a partnership pathway agreement with Malvern Hills Private Practice which means a seamless service from diagnosis through to treatment.
Stage 6. A detailed Clinical Report will be provided (around 20 pages) plus a personal summary, as well as letters for reasonable adjustments for study and work (no extra fee).
