The Ethical Principles for Psychologists and Code of Conduct has been recently revised. The organization of the code changed, and the language was made more specific. A number of points relevant to school psychology are explicitly stated in the code. A clear advantage of including these items in the code is the assistance to school psychologists negotiating ethical dilemmas in their work setting. This article provides an overview of the revisions in the code most applicable to school psychologists and a detailed analysis of three areas of the code: psychological assessment, the implications and application of the modifiers in the code that guide ethical decision making and correct conduct, and diversity issues.
