Conners 3 Assessment
The Conners 3 is one of the most comprehensive ADHD tests available. It doesn’t just identify behaviours associated with ADHD, it also checks whether the responses themselves are reliable. This makes it an invaluable part of our Gold Standard ADHD assessment. At Global Education Testing, we combine Conners 3 results with objective attention, cognitive and academic testing to understand not only what a student is experiencing, but why.
The Conners 3 is a standardised behavioural rating scale designed for children and young people aged 6 to 18 years. It gathers information from parents, teachers and, where appropriate, the student themselves to build a detailed picture of behaviour across different settings.
Because it measures far more than just ADHD symptoms, the Conners 3 helps us understand how attention difficulties affect learning, organisation, behaviour and everyday school life.
Why the Conners 3 Matters
No single questionnaire can diagnose ADHD.
However, the Conners 3 provides one of the most detailed behavioural profiles available and includes an important feature many other questionnaires lack: validity checks.
These built-in measures help identify responses that are inconsistent, unusually negative or unusually positive. This improves confidence that the questionnaire accurately reflects the student’s day-to-day functioning rather than a moment of frustration, misunderstanding or over-reporting.
For our Educational Psychologists, this additional level of quality control provides valuable context when interpreting the assessment as a whole.
What Does the Conners 3 Measure?
The Conners 3 looks beyond the core symptoms of ADHD to build a much broader understanding of how a student functions.
It assesses:
Inattention
- Difficulty concentrating
- Easily distracted
- Forgetfulness
- Losing track of tasks
Hyperactivity and Impulsivity
- Restlessness
- Excessive movement
- Acting without thinking
- Difficulty waiting or taking turns
Executive Functioning
- Organisation
- Planning
- Starting tasks
- Managing time
- Completing work independently
Learning Problems
- Classroom performance
- Academic confidence
- Difficulties that may indicate an underlying learning disorder
Defiance and Aggression
- Emotional regulation
- Challenging behaviour
- Conflict with adults
Peer Relations
- Friendships
- Social interaction
- Relationships with classmates
Together, these scales provide a much richer picture of a student’s strengths and challenges than ADHD symptom counts alone.
Why the Conners 3 Cannot Diagnose ADHD by Itself
The Conners 3 records what people observe. It cannot determine what is causing those behaviours. For example, elevated attention scores may reflect:
- Dyslexia
- Dyscalculia
- Working memory difficulties
- Anxiety
- Autism
- Learning through an additional language
- Exceptionally high ability leading to boredom in class
Many of these students appear inattentive, but each requires a different diagnosis and a different support plan.
This is why behavioural questionnaires are only one part of our comprehensive psychoeducational assessment.
How the Conners 3 Fits Into Our Gold Standard Assessment
The Conners 3 provides detailed behavioural information. Our other assessments explain why those behaviours are occurring.
For example:
- SNAP-IV confirms whether ADHD behaviours are seen consistently across home and school.
- MOXO Continuous Performance Test objectively measures attention, impulsivity, timing and hyperactivity under standardised conditions.
- WISC-V or WAIS-IV evaluates cognitive ability, including working memory and processing speed.
- WIAT-III assesses academic attainment to identify learning disorders that may explain classroom difficulties.
When these assessments all point in the same direction, we can reach a diagnosis with far greater confidence than any questionnaire could provide on its own.
Why the Student’s Voice Matters
As children grow older, they often experience difficulties that adults simply cannot see.
They may work twice as hard to achieve average results, spend enormous mental effort staying focused or experience constant internal distraction despite appearing calm in class.
For students aged 8 years and above, the Conners 3 includes a self-report questionnaire that captures these experiences directly.
Comparing student, parent and teacher perspectives often provides valuable clinical insight, particularly when different people observe different aspects of the student’s behaviour.
Why Expert Interpretation Is Essential
Completing the Conners 3 is straightforward. Interpreting it correctly requires specialist clinical expertise.
A score should never be viewed in isolation. Educational Psychologists consider the student’s age, educational setting, academic expectations and the results of every other assessment before reaching any conclusions.
For example, a teacher in a highly selective international school may rate attention differently from a teacher in another educational setting. Similarly, differences between parent and teacher ratings often reveal important diagnostic information rather than a problem with the questionnaire itself.
At Global Education Testing, every Conners 3 assessment is interpreted by an HCPC-registered Educational Psychologist and considered alongside objective cognitive, academic and attention testing before any diagnosis is made.
Every Global Education Testing assessment includes the Conners 3 completed by parents, by school and, where age appropriate, by the student, with content scales, DSM-5-TR symptom scales and validity indices reported.
The report interprets those ratings against objective attention data, cognitive ability and academic attainment, states the diagnosis, and specifies the examination accommodations the findings support.
It sets out immediately actionable recommendations for school and home, is delivered within 7 days, and is backed by our Exam Board Acceptance Guarantee.
