Promoting ethical practices in assessment is considered to be a very important goal of the organizations involved in assessment. Codes are intended to increase the awareness of ethical practice among their memberships and to promote ethical uses of assessment in various contexts such as teaching, counseling, evaluation, and research. The level of enforcement that each organization takes is directly tied to the character of membership in the organization, whether it is voluntary or tied to a credential or designation. The more stringent the requirements are for membership in an organization, the easier it is for that organization to establish a more formal means of discipline and enforcement. Educating others to understand and to engage in ethical practices is a critical goal. Illustrations of good and bad practice within realistic assessment contexts and discussions of ethical dilemmas are excellent ways of promoting ethically responsible practice in assessment. (JBJ)
