assessmentsADHD Assessment (Children, Adolescents and Adults)
Comprehensive ADHD Assessment & Diagnostic Services
Attention-Deficit/Hyperactivity Disorder (ADHD) can impact executive functioning, emotional regulation, academic performance, and daily life. Obtaining a clear, formal assessment is the first step toward understanding these challenges and accessing the right support.
At Sydney Psychology Group, we provide thorough, evidence-based ADHD assessments. Our process focuses on identifying specific behavioural patterns and executive functioning challenges to help you or your child find clear pathways forward and provided tailored interventions to address individual needs.
ADHD Assessment Process
The assessment process typically involves three sessions, clinical questionnaires, and a formal letter to confirm the diagnosis if criteria are met.
-
Prior to your first appointment, you will complete a detailed intake form. This form will be sent to you 3–4 weeks before your first scheduled session to gather essential developmental and behavioural history.
-
A 50-minute clinical session to review your completed intake form, gather relevant background information, and determine whether a formal ADHD assessment is appropriate.
-
A range of standardized questionnaires (including gold-standard tools like the Conners 4 to evaluate attention, hyperactivity, executive functioning, and emotional regulation) will be provided for completion by yourself and others close to you (such as parents, partners, or teachers). At this stage, we also request school reports and any relevant collateral information from family members.
-
This session takes between 1.5 to 2 hours. It focuses deeply on the specific clinical symptoms of ADHD to determine whether formal diagnostic criteria are met.
-
Our clinicians review and analyse all gathered data, session notes, and psychometric results.
Standard Inclusion: A formal summary letter is completed to be sent to relevant health professionals as requested. This clinical analysis and letter writing takes approximately 4–6 weeks to complete.
Optional Full Report: If you require a comprehensive, formal psychological report with detailed classroom/workplace recommendations, this can be provided for an additional fee.
-
During this standard-length session, your psychologist will explain the assessment letter, discuss the outcome, and focus on education, support strategies, and planning your next steps.
