Not meeting the social, emotional, behavioural and educational needs of students with ADHD in the short-term can lead to a greater likelihood of falling academically behind their non-ADHD peers in their year, suspension, or expulsion. In the longer term, it can contribute to higher rates of suicide, depression, anxiety, drug use and criminality.
Conversely, meeting these needs can result in many benefits for you as their teacher. For example, it can make your job less stressful and more satisfying. Additionally, the benefits for students with ADHD (and the rest of your class) can be life-changing and enable them to focus on strengths such as creativity and problem-solving, giving many highly successful people their drive and edge.
