Teachers should recognize the limits of their expertise in dealing with students with chronic behavioral problems and make appropriate referrals. Before referring students outside the classroom, teachers must document intervention strategies attempted. Initial referrals may be made to parents, with a call, email or letter describing the problem, interventions tried, and proposed plan. For some students, their behavior resists all modification attempts and is a response to negative environmental influences like failure in and out of school. When meeting with parents, conferences should avoid blame and focus on collaboratively helping the student regulate their behavior. Referrals to specialized assistance may be needed for problems unresponsive to classroom treatment or beyond a teacher's expertise.
