Psychological tests are valuable tools used in psychodiagnostics to assess intelligence, personality, aptitude, emotional functioning, cognitive abilities, interests, and mental health conditions. Since the results of these tests influence important decisions related to education, employment, clinical treatment, and legal matters, psychologists must follow strict ethical principles while administering, scoring, interpreting, and reporting psychological tests. Ethical testing protects the dignity, rights, and welfare of individuals while ensuring the validity and reliability of assessment outcomes. One of the most important ethical principles is informed consent. Before conducting a psychological test, the examiner should explain the purpose, nature, procedures, possible benefits, and limitations of the assessment. Individuals should voluntarily agree to participate without coercion. In the case of minors or individuals with impaired decision-making capacity, consent should be obtained from parents or legal guardians while also seeking the individual's assent whenever possible. Confidentiality is another fundamental principle. Test scores, responses, reports, and personal information must be kept confidential and shared only with authorized persons or with the individual's permission. Confidentiality may be breached only under legally or ethically justified circumstances, such as when there is a risk of serious harm
