RESUMEN: Los tests o instrumentos de medida estandarizados se han convertido en una herramienta indispensable en las ciencias sociales, tales como la Psicología, la Sociología y la Educación. Por ello es primordial que los profesionales que los emplean se aseguren de que estos instrumentos funcionan del mismo modo en los distintos grupos existentes en función de variables socio-demográficas como el sexo, la cultura, la etnia, etc. Cuando alguno de los ítems funciona diferencialmente para los distintos grupos se habla de funcionamiento diferencial del ítem (DIF). Precisamente el objetivo del presente trabajo se centra en presentar una breve introducción al concepto de DIF y a los métodos existentes para su detección.
