ADHD in Kids: Signs, Assessment, and What to Do Next

Is your child finding it hard to concentrate, always on the move, or acting without thinking? Maybe their teacher has mentioned concerns, or you’ve noticed they struggle to follow instructions, finish tasks, or stay seated for long. If this sounds familiar, you might be wondering whether ADHD could be the reason for your child’s concentration issues.

ADHD (Attention Deficit Hyperactivity Disorder) is a common neurodevelopmental condition that affects children’s ability to focus, regulate impulses, and manage their energy levels. While all kids can be inattentive or active at times, ADHD symptoms tend to be more persistent, noticeable, and impact daily life.

As a parent, it’s natural to wonder whether your child’s behaviour is simply a part of growing up or something more. Understanding ADHD and getting the right assessment can provide clarity and help your child access the support they need.

ADHD or Just Typical Behaviour?

All kids get distracted, interrupt, or fidget from time to time. But for children with ADHD, these behaviours are:

  • More frequent and intense than their peers
  • Ongoing, rather than just occasional phases
  • Present across multiple settings, like home, school, and social situations
  • Interfering with learning, friendships, or daily life

Some parents say their child is bright and full of ideas but struggles to get things done. Others describe children who are constantly on the move, acting before thinking, or feeling overwhelmed by emotions.

So how do you know when it’s time to seek help?

Signs of ADHD in Kids

ADHD symptoms vary from child to child, but they often fall into three main types:

Inattentive ADHD

  • Gets easily distracted and struggles to focus
  • Often forgets things – homework, lunchboxes, school bags
  • Finds it hard to follow multi-step instructions
  • Struggles to complete tasks, even ones they enjoy

Hyperactive-Impulsive ADHD

  • Always moving – fidgeting, tapping, unable to sit still
  • Interrupts conversations or blurts out answers
  • Acts without thinking about consequences
  • Struggles with turn-taking and waiting

Combined ADHD (the most common type)

  • A mix of both inattention and hyperactivity, making it harder to focus, follow instructions, stay organised, and regulate emotions.
  • Girls with ADHD are more likely to have inattentive symptoms, which can go unnoticed because they may not be disruptive in class.
  • Boys with ADHD are often diagnosed earlier, as their hyperactive-impulsive traits may be more noticeable.

If your child shows these signs regularly and it’s affecting school, home life, or friendships, an ADHD assessment with a child psychologist can provide clarity.

When Should a Child Be Assessed for ADHD?

Many parents wonder: Is my child too young for an ADHD diagnosis?

The answer depends on how persistent and disruptive the symptoms are.

Preschool-age children (under 5) may show ADHD-like behaviour because they’re still developing self-regulation. However, if their challenges are extreme compared to peers, it may be worth discussing concerns with a professional.

School-aged children (6+) are usually the best candidates for an ADHD assessment because they are expected to focus for longer, follow routines, and manage learning independently.

If your child’s difficulties are impacting their ability to learn, socialise, or function at home, seeking an assessment can be a turning point in getting the right support.

What Happens in an ADHD Assessment?

Diagnosing ADHD isn’t about ticking off a checklist – it requires a detailed look at your child’s behaviour, attention, and learning profile.

A comprehensive ADHD assessment typically includes:

  • Parent & teacher questionnaires – Observing behaviour across home and school
  • Developmental history – Understanding milestones, past behaviours, and family history
  • Cognitive & academic testing – Using tools like the WISC and WIAT to assess attention, working memory, and executive function
  • Observational tasks – Evaluating focus, impulsivity, and hyperactivity in structured settings
  • A full diagnostic report – Providing a clear diagnosis and practical recommendations

For many families, an ADHD assessment is the first step in accessing support at school and at home. It can also help child’s GP or paediatrician to better understand their behavioural and learning needs.

Why Getting an ADHD Diagnosis Can Make a Difference

Some parents worry that a diagnosis will label their child. But in reality, understanding how your child’s brain works can be incredibly empowering.

  • Access school support – Adjustments and strategies can help them focus and succeed.
  • Build confidence – Kids with ADHD often thrive once they get the right support.
  • Improve family relationships – Parents gain tools to manage behaviour in a positive way.
  • Find the right strategies – Knowing what helps (and what doesn’t) makes life easier for everyone.

With early intervention and the right support, kids with ADHD can learn, grow, and reach their potential – at school, at home, and in life.

What’s Next?

If you’ve been wondering about ADHD, now is the time to find out more.

  • Speak with your child’s teachers – If your child struggles with attention and concentration, their classroom or specialist learning support/diverse learning staff may be able to assist.
  • Talk to a professional – A paediatrician or child psychologist can assess your child’s strengths and challenges.
  • Consider an ADHD assessment – If symptoms are persistent, getting a diagnosis can open doors to support.
