Which information sources are typically integrated in ADHD assessment in a school setting, and what pitfalls should be avoided?

• A. Behavior rating scales alone, with no clinical interview or observation.
• B. Only teacher ratings are used, with no other data collected.
• C. Rely on a single testing source and ignore cultural context.
• D. Behavior rating scales (teacher and parent), clinical interview, observation, academic achievement, processing measures; avoid over-reliance on a single source, consider cultural/familial context, ensure age-appropriate norms, assess impairment across settings.

Answer: (D)

ADHD assessment in school relies on gathering information from multiple sources and through multiple methods to build a complete picture of symptoms and how they affect daily functioning. Behavior rating scales from both teachers and parents help document how often and how severely symptoms show up across settings, while a structured clinical interview provides developmental history, context, and rule-outs that scales alone can miss. Classroom or systematic observations show how the child behaves in real instructional tasks, and academic achievement tests reveal whether learning in the classroom is being impacted. Processing measures add detail about cognitive factors that can accompany or mimic ADHD symptoms, such as working memory or processing speed, which helps differentiate ADHD from other concerns.

The key is to avoid relying on a single data source or method, and to consider cultural and familial context, age-appropriate norms, and functioning across settings. This multi-method, multi-informant approach reduces bias, improves accuracy, and supports appropriate planning and interventions.
