IS THIS THE RIGHT STEP?

Who may benefit from an ADHD assessment?

If any of these situations sound familiar, an ADHD assessment can provide clarity, identify strengths and challenges, and help determine whether ADHD or other factors may be contributing to difficulties with attention, executive functioning, organization, or everyday responsibilities.

Difficulty Paying Attention

Difficulty sustaining attention during school, work, conversations, reading, or everyday tasks, even when trying to focus.

Organization & Time Management Challenges

Frequently losing items, missing deadlines, forgetting appointments, or struggling to organize tasks and complete projects.

Hyperactivity or Restlessness

Feeling constantly on the go, frequently fidgeting, having difficulty sitting still, or experiencing an ongoing sense of inner restlessness.

Impulsivity

Interrupting conversations, acting before thinking, making impulsive decisions, or finding it difficult to pause before responding.

Executive Functioning Difficulties

Challenges with organization, planning, prioritizing, time management, remembering information, starting tasks, or following through on responsibilities.

Emotional Regulation

Difficulty managing frustration, emotional reactions, stress, or mood changes that may be affecting relationships or daily life.

UNDERSTANDING THE ASSESSMENT

What is an ADHD assessment?

An ADHD assessment is a focused psychological evaluation that examines difficulties with attention, organization, executive functioning, impulse control, hyperactivity, and emotional regulation. It helps clarify how these challenges may be affecting learning, work, relationships, and everyday responsibilities.

The assessment looks beyond a checklist of symptoms. Depending on the individual’s needs, it may include clinical interviews, standardized measures, questionnaires, behavioural observations, and a review of relevant developmental, educational, medical, and psychological history.

The goal is to determine whether diagnostic criteria for ADHD are met, identify individual strengths, and consider other factors that may be contributing to current concerns. The findings are used to develop practical, evidence-informed recommendations for school, post-secondary education, the workplace, relationships, and daily life.

ADHD can occur on its own or alongside learning difficulties. When reading, writing, mathematics, memory, or academic achievement are also significant concerns, a psychoeducational assessment may be recommended. When concerns extend across multiple areas of learning, attention, development, behaviour, or emotional functioning, a Neurodevelopmental & Learning Assessment may provide the more comprehensive evaluation required. Our team will help determine which assessment best fits your needs.

At Chisholm Centre, each ADHD assessment is completed through a collaborative process and reviewed by a senior psychologist before the results are shared. Children, teens, adults, and families receive a feedback consultation and a written report outlining the findings, diagnostic conclusions where appropriate, recommendations, and practical next steps.
