Practitioner-members of the National Association of School Psychologists (N = 208) completed questionnaires regarding their ethics training, preparedness, the types of ethical transgressions and dilemmas encountered in the previous year, and the strategies used to solve problems. Respondents who received multilevel training in ethics (ethics coursework, ethics instruction in multiple classes, ethics addressed in practicum/internship) perceived themselves to be better prepared to tackle difficult challenges and were more likely to use a systematic problem-solving strategy when faced with an ethical dilemma than respondents who did not receive multilevel training. Assessmentrelated ethical transgressions and failure to follow up on interventions were the two most commonly witnessed types of ethics code violations; troublesome dilemmas included whether to suspect child abuse, whether to tell parents about their child's risky behavior, and how to handle administrative pressure to engage in unethical actions. Implications for ethics training are discussed. C 2011 Wiley Periodicals, Inc.School psychology practitioners are likely to encounter two types of ethically challenging situations: ethical dilemmas and transgressions. Dilemmas occur when "there are good but contradictory ethical reasons to take conflicting and incompatible courses of action" (Knauss, 2001, p. 231; also Beauchamp & Childress, 2001). Some ethical dilemmas are quickly and easily resolved; others are troubling and time-consuming (Sinclair, 1998). Ethical transgressions or violations are those acts that go against professional expectations for ethical conduct and violate enforceable ethics codes. Ethical transgressions can result in harm to students or other clients and create a problematic situation for colleagues who must decide whether and how to confront the misconduct.Several methods for gathering information about ethical dilemmas and transgressions encountered by psychologists have been developed. The critical incident technique (Flanagan, 1954) is a set of procedures for collecting reports from real-life settings of particular types of problem situations, with the goal of describing the types of problems encountered in "real world" practice settings. An advantage of this approach is that it allows the respondent, rather than the researcher, to identify the types of situations that create ethical challenges for practitioners. A second advantage is that respondents are likely to describe situations that capture the complexities of contemporary practice. A disadvantage of this approach is that it characteristically results in a low return rate, and respondents may be most likely to describe situations that were particularly troublesome rather than the ethical problems they frequently encounter.Another approach to studying real-world ethical challenges is to use a structured questionnaire to ask practitioners whether they have experienced or witnessed various types of ethical dilemmas and transgressions. One advantage of a structured questionnair...
