Which of the following is considered a violation of professional standards?

The violation of professional standards is primarily associated with any form of sexual misconduct by licensed professionals. Sexual misconduct undermines the ethical principles of the psychological profession, which emphasize the importance of maintaining professional boundaries and the trust that is essential for effective therapeutic relationships. Such misconduct not only harms the affected individuals but also damages the integrity of the profession as a whole.

Professional standards require psychologists to uphold a code of ethics that prioritizes the well-being of clients and protects them from exploitation and harm. Engaging in sexual misconduct is a serious breach of these standards, as it exploits the power differential inherent in the therapist-client relationship and can have lasting negative effects on the client.

In contrast, maintaining client confidentiality, using evidence-based practices, and participating in continuous education are all considered ethical and professional behaviors that uphold the integrity of the practice. They contribute positively to client care and improve the effectiveness of psychological services. Thus, the only option that represents a clear violation of professional standards is sexual misconduct by licensed professionals.
