Emotional or behavior disorder means an established pattern of one or more of the following emotional or behavioral responses:
- withdrawal or anxiety, depression, problems with mood, or feelings of self-worth.
- disordered though processes with unusual behavior patterns and atypical communication styles; or
- aggression, hyperactivity, or impulsivity.
The established pattern of emotional or behavioral responses must adversely affect educational or developmental performance, including intrapersonal, academic, vocational, or social skills; be significantly different from appropriate age cultural, or ethnic norms; and be more than temporary, expected responses to stressful events in the environment. The emotional or behavioral responses must be consistently exhibited in at least three different settings, two of which must be educational settings, and one other setting in either the home, child care, or community. The response must not be primarily the result of intellectual, sensory, or acute or chronic physical health conditions.
