It is also self-proclaimed as “the most robust and reliable” system available, with its greatest benefit to help educators improve their teaching practices. This study critically examined the effects of SAS® EVAAS® as experienced by teachers, in one of the largest, high-needs urban school districts in the nation – the Houston Independent School District (HISD) . Using a multiple methods approach, this study critically analyzed retrospective quantitative and qualitative data to better comprehend and understand the evidence collected from four teachers whose contracts were not renewed in the summer of 2011, in part given their low SAS® EVAAS® scores. This study also suggests some intended and unintended effects that seem to be occurring as a  \nManuscript received: 03/01/2012  \nRevisions received: 03/03/2012  \nAccepted: 03/04/2012  \nEducation Policy Analysis Archives Vol. 20 No. 12 2  \nresult of SAS® EVAAS® implementation in HISD. In addition to issues with reliability, bias, teacher attribution, and validity, high-stakes use of SAS® EVAAS® in this district seems to be exacerbating unintended effects.  \nKeywords: value-added models (VAMs); teacher effectiveness; teacher quality; teacher evaluation; accountability.  \nEl SASSistema de Evaluación de la Educación de Valor Agregado (SAS® EVAAS®): Algunosefectos intencionales y no intencionales en un sistema escolar urbano de gran tamaño.  \nResumen: El SAS Sistema de Evaluación de la Educación de Valor Agregado (SAS® EVAAS®) es el sistema de valor agregado más ampliamente utilizado en el país. También se auto-proclama como el sistema disponible “más robusto y fiable\", siendo su mayor beneficio poder ayudar a los educadoresa mejorar sus prácticas de enseñanza. Las investigadoras de este estudio examinaron los efectos de SAS® EVAAS®, experimentado por docentes, en uno de los distritos escolares urbanos más grandes y con mayores necesidades educativas de la nación: el Distrito Escolar Independiente de Houston (HISD) . A través de evidencias obtenidas con cuatro docentes cuyos contratos no fueron renovados en el verano de 2011, en parte debido a sus bajas puntuaciones en SAS® EVAAS®, sedetallan algunos de los efectos deseados y no deseados que parecen estar ocurriendo como resultadode la aplicación SAS® EVAAS® en HISD. Además de los problemas con la fiabilidad, el sesgo, la atribución docente, la validez, el uso de SAS® EVAAS® con consecuencias severas en este  \ndistrito parece exacerbar los efectos no intencionales.  \nPalabras clave: modelos de valor añadido (VAM); eficacia docente; calidad docente;  \nevaluación docente; rendición de cuentas.  \nO SAS Sistema de Avaliação do Valor Agregado Educativo (SAS® EVAAS®): Alguns efeitos intencionais e não intencionais em um sistema escolar urbano de grande tamanho.
