The Mexican Secretariat of Public Education (in Spanish Secretaría de Educación Pública, SEP) is a federal government authority with Cabinet representation and responsibility for overseeing the development and implementation of national educational policy and school standards in Mexico. The Secretariat has several buildings distributed all over the country but its main offices, initially confined to the Old Dominican Convent of the Holy Incarnation in the oldest borough of Mexico City, have extended to the House of the Marquess of Villamayor (also known as the Casa de los adelantados de Nueva Galicia, built in 1530), the Old House of don Cristóbal de Oñate, a three-times Governor and General Captain of New Galicia (also built in 1530) and the Old Royal Customs House (built in 1730-31).
