The proficiency with which teachers of students with emotional and behavioural disorders (EBD) plan for, provide instructional activities, and address the challenging behaviour of their students is influenced by the nature of their preservice teacher preparation. The purpose of this study was to examine educators' perceptions of the importance of preservice field-based experiences. Results indicate that educators of students with EBD consider student teaching of both students with EBD and students without disabilities very important experience. Educators with more than 10 years experience also indicated that the observation of police, parole, and judicial services concerned with students with EBD was an important preservice experience. Limitations of the study and implications for preservice teacher preparation are discussed.
