What Behavioural Signs in Class Indicate ADHD? 

ADHD classroom behaviour often includes a tendency to fidget, move around excessively, or talk out of turn. These actions are frequently mistaken for misbehaviour, but they are more accurately understood as symptoms of an underlying difficulty in maintaining focus or controlling impulses. Common signs include disruptive behaviour, difficulty following instructions, and struggles with staying seated or focused for extended periods. 

Common Symptoms 

ADHD classroom behaviour often exhibits a tendency to fidget, move around excessively, or talk out of turn. These actions are often mistaken for misbehaviour, but they are more likely a result of an underlying inability to maintain focus or control impulses. Disruptive behaviour can include talking excessively, interrupting the teacher or other students, or having difficulty waiting for their turn in activities. This impulsivity makes it hard for the child to follow social norms within the classroom. 

Teachers often observe that the child frequently changes tasks or becomes easily distracted by external stimuli in the classroom. Teacher observations are crucial in identifying potential ADHD symptoms. Teachers who recognise patterns of inattention, impulsivity, or hyperactivity in students can help prompt a more thorough evaluation. Early intervention and tailored strategies, such as providing a quiet workspace or breaking tasks into smaller steps, can significantly improve the child’s classroom experience.
