What Does a Psychologist Do During ADHD Evaluation?

Posted October 13, 2025 Updated October 13, 2025 Author: Avery Lombardi, MSc Reviewed by: Dr. Rebecca Fernandez, MBBS

A psychologist ADHD evaluation involves several key steps to determine whether an individual meets the criteria for ADHD. The goal is to build a full picture of how symptoms affect every day functioning, using a mix of structured tools and personal insights. Psychologists are specially trained to carry out these evaluations, often using a combination of clinical interviews, behavioural assessments, and standardised questionnaires.

The process typically begins with a clinical interview, where the psychologist asks detailed questions about the individual’s history, including early development, school performance, family dynamics, and current difficulties. This helps identify patterns consistent with ADHD, as well as any other conditions that might explain the symptoms.

Next, the psychologist may use behavioural assessments to evaluate how attention, organisation, and impulse control function in different settings such as home, work, or school. These assessments often include rating scales completed by the individual and people close to them (like parents, teachers, or partners), along with cognitive testing in some cases.

What to Expect in an ADHD Evaluation

Here’s what a psychologist typically includes in an ADHD evaluation:

Clinical Interview

A detailed conversation exploring medical, psychological, educational, and social history.

Standardised Questionnaires

Tools like the ASRS or Conners Scale are used to measure the frequency and severity of ADHD symptoms.

Behavioural Assessment

Observations or reports about behaviour in daily life, focusing on attention, impulse control, and hyperactivity.

In conclusion, a thorough psychologist ADHD evaluation ensures that the diagnosis is accurate and that appropriate support strategies can be recommended.
