La práctica de la evaluación psicodiagnóstica plantea a los profesionales una variedad de interrogantes metodológicos, teóricos y éticos. El acercamiento a la misma puede realizarse desde una diversidad de teorías psicológicas que complejizan el objeto de estudio. Por lo tanto debemos leer en la praxis de cada profesional un determinado sistema ético y en cada una de sus intervenciones una teoría ética y filosófica que expresa, a su vez, una teoría de valores y una visión particular del mundo. Este trabajo propone reflexionar sobre las cuestiones normativas que sostienen la práctica de la evaluación psicodiagnóstica. Se considerarán los conceptos de Psicoética y Deontología Profesional para poder definir espacios de reflexión e incumbencias . Palabras clave: ética- psicodiagnósticonormas- praxis. Palabras clave Ética, Psicodiagnóstico, Normas, Praxis Abstract ETHICS AND PSYCHODIAGNOSTIC The psychodiagnostic assessment practice practitioners raises a variety of questions methodological, theoretical and ethical.The approach to it may be made from a variety of psychological theories that complicate the study object.
