Se presentan los resultados del análisis comparativo de datos obtenidos en la aplicación del instrumento "Valué Survey" que mide el Perfil Valórico -adaptado por Brinkmann et al. (1999) para Chile- a veinte alumnos de la Carrera de Obstetricia y Puericultura al ingreso y al término de su formación profesional; ejercicio para el que se utilizó la prueba t de student para grupos relacionados. Durante la trayectoria académica un 75% de los componentes de los Perfiles Valóricos reducen su importancia como elementos de influencia para el comportamiento y las decisiones que organizan la vida cotidiana de los alumnos.<br>We present comparative data obtained under the application of an instrument called "Valué Survey", employed to detect valoric profile levéis, adapted to Chle by Brinkman et al.
