This handbook provides an overview of the consultation role for the school psychologist and distinguishes between consultation and other forms of school psychological services. Three major consultation models in school psychology are reviewed: (1) mental health consultation; (2) organization-development consultation; and (3) behavioral consultation. The characteristics of behavioral consultation are defined and discussed, and its historical and theoretical background are examined. The materials identify stages and verbalizations in behavioral consultation and provide examples of practice exercises. Problem identification and analysis are discussed and suggestions are given for implementation. Problem evaluation and its importance to accountability are discussed. Examples of interview forms are included along with practice exercises throughout the document. (JAC)
