The school experience can be challenging for students with ADHD.
Students usually are identified only after consistently demonstrating a failure to understand or follow rules or to complete required tasks.
Other common reasons for referral include frequent classroom disruptions and poor academic performance.
Studies found that students with ADHD, compared to students without ADHD, had persistent academic difficulties that resulted in the following: lower average marks, more failed grades, more expulsions, increased dropout rates, and a lower rate of college undergraduate completion (Weiss & Hechtman as cited in Johnston, 2002; Ingersoll, 1988).
The disruptive behavior sometimes associated with the disorder may make students with ADHD more susceptible to suspensions and expulsions.

ADHD is one of the most commonly diagnosed conditions of children (Centers for Disease
Control and Prevention, 2015).

In a 2016 Centers for Disease Control and Prevention study, scientists found that 6.1 million children aged 2-17 years living in the U.S. had been diagnosed with attention-deficit/hyperactivity disorder (ADHD), which is similar to previous estimates.

Ages 2-5: Approximately 388,000 children
Ages 6-11: Approximately 2.4 million children
Ages 12-17: Approximately 3.3 million children

The diagnostic term attention deficit/hyperactivity disorder (ADHD) refers to individuals who display patterns of inattention, impulsivity, and overactive behavior that interfere with daily functioning (American Psychiatric Association [APA], 2013).

The goal of behavior management strategies is to help students learn to manage their own
behavior. The following strategies are most effective when used in conjunction with evidence based instructional strategies.


Prevention Strategies
Here are some preventive measures that support students in demonstrating positive
behavior.


Nonverbal Supports: Together with the student, develop inconspicuous,
nonverbal messages such as eye contact, hand gestures, or other signals that teach
students to recognize the conditions that trigger specific behaviors. Once the
system is developed, students can learn to manage their behavioral responses
before they occur.
