Here's the honest, reassuring answer.*\n\n## In short\nOppositional Defiant Disorder (ODD) isn't split into named *types* — instead, clinicians describe it by **severity** and by **clusters of behaviour**. Severity is graded as **mild, moderate or severe**, based on how many settings the behaviour shows up in (home, school, with peers). The behaviours themselves fall into three recognised groups: an **angry/irritable mood**, **argumentative/defiant behaviour**, and **vindictiveness**. None of this is a label on your child's character — it's simply a way to understand the pattern and shape the right support.\n\n## The levels (severity)\nClinical frameworks describe ODD by how widely the behaviour spreads, not by a child's worth:\n- **Mild** — the behaviours occur mainly in **one setting**, usually at home.\n- **Moderate** — the behaviours appear in **at least two settings**, for example home and school.\n- **Severe** — the behaviours show up in **three or more settings** or across most of the child's day.\n\nThis matters because the same child can look very different at home versus the classroom, and that pattern guides how and where support is offered.\n\n## The clusters (behaviour groups)\nRather than separate \"types\", the behaviours of ODD are understood in three overlapping groups:\n- **Angry or irritable mood** — frequently losing temper, easily annoyed, often resentful.\n- **Argumentative or defiant behaviour** — arguing with adults, refusing rules, deliberately annoying others, blaming others.\n- **Vindictiveness** — being spiteful or seeking to \"get back\" at others.\n\nMany children show a mix. The pattern, frequency and how out-of-step it is for the child's age all matter far more than any single incident — every child argues sometimes.\n\n## The Pinnacle way\nAbilityScore® is part of Pinnacle’s developmental assessment.
