I imagine it is a very natural part of ADHD research to work with children, either as a counselor, teacher, or a supporting teacher.

It may not be the case here, but Laboratory Schools are pretty common in early childhood development programs. Basically normal elementary classrooms located on college campuses for researchers to observe.

>A laboratory school or demonstration school is an elementary or secondary school operated in association with a university, college, or other teacher education institution and used for the training of future teachers, educational experimentation, educational research, and professional development....Some lab schools are only for preschool or kindergarten children, some are preschool through fifth or sixth grade, and some continue through high school...Laboratory school classrooms may be observed by university professors to assess the student-teacher, but it is desired that the observation be done without the students or student-teachers aware of the observation, thereby avoiding creating a distraction or disruption of classroom activities.

University researcher would be my guess. These are pretty common, you know.
