The Conners-3 and the AbilityScore answer different questions. The Conners-3 is a focused rating-scale tool that screens for ADHD and related behaviours in children aged about 6–18, using parent, teacher and self-report forms. The AbilityScore is a broader clinician-administered developmental assessment that maps a child's whole profile against their own baseline. They are complementary, not rivals, and neither is a diagnosis on its own.

*When you're weighing up which assessment will truly help your child, it helps to know what each one is actually built to do.*

## In short
The [Conners 3rd Edition](/conners-3) and the AbilityScore® answer different questions. The Conners-3 is a focused rating-scale tool that screens for ADHD and related behaviours (like defiance or learning difficulty) in children roughly 6–18 years, using parent, teacher and self-report forms. The AbilityScore® is a broader, clinician-administered developmental assessment that maps your child's whole profile — communication, behaviour, learning, motor and more — against their own baseline. They're complementary, not rivals: one is a targeted lens, the other a full developmental picture.

## How the two compare

**What each measures**
- **Conners-3** — a standardised behaviour-rating questionnaire focused on attention, hyperactivity/impulsivity, and associated areas such as oppositional behaviour and executive function. It's filled in by parents, teachers and (for older children) the child themselves, then scored against age and gender norms.
- **AbilityScore®** — a clinician-administered structured assessment that looks across multiple developmental domains, not just attention. It's designed to establish where your child is today and to track meaningful change over time.

**Age range**
- Conners-3 is validated for school-aged children and teens (about 6–18 years).
- AbilityScore® supports a wider developmental span, including younger children where ADHD-style tools aren't yet appropriate.

**What you get**
- Conners-3 gives a focused snapshot useful as part of an ADHD evaluation.
- AbilityScore® gives a whole-child baseline that turns into a practical therapy plan and a way to measure progress.

**The honest bottom line:** neither tool, on its own, is a diagnosis. The Conners-3 is best thought of as one valuable input; the AbilityScore® is the structured developmental measure our clinicians use to plan and track care.

## When each is used
If attention, restlessness or impulsivity at school is the main concern, a clinician may use a Conners-3 rating set as part of a wider evaluation. If you want a complete developmental picture — speech, behaviour, learning, motor and social skills together — the AbilityScore® is the broader starting point. Often a clinician uses both: the wide-angle map first, then targeted tools where they add detail.

## The Pinnacle way
Developmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional., under the care of a qualified clinician — never from an online form or a single questionnaire. Our AbilityScore® is a clinician-administered structured assessment that measures your child against *their own* baseline, backed by 2.5 billion+ data points and 25 million+ therapy sessions across 70+ centres. Where attention and behaviour need support, our clinicians pair it with [behavioural therapy](/behavioural-therapy).

This is general information, not a diagnosis — individual assessment and diagnosis require an appropriately qualified healthcare professional.
