Model Gender impact assessments have been required by law in the Basque Country since 2005, in the framework of the Equal opportunities between women and men Act. Furthermore, the province of Gipuzkoa, within the Basque Country, has also developed its own gender Equality Act, which regulates in detail the gender impact assessment process. Gender impact assessment was applied for the rst time in 2007 by the Basque government, when the assessment procedure was established. Since then, reports have been issued on more than 500 decrees and laws. After 7 years, gender impact assessment is a consolidated practice very strongly embedded within the Basque regional government. Subsequently, the Diputación Foral de Gipuzkoa (government of the Basque province of Gipuzkoa) developed a more tailored procedure for gender impact assessments, which was approved at the senior political level in 2011. Since then, gender impact assessments have also been carried out at this regional level. Model Actors involved Guidelines Strenghts and weaknesses
