AbstractThe Gabaldon school buildings represent one of the important contributions of the Americans to the Philippines, the education system. These school buildings were named after the assemblyman from Nueva Ecija, Rosario Gabaldon, who authored the law that sets aside funds to construct school buildings throughout the country. Some of these Gabaldon school buildings survived after more than a hundred years when the law was passed in 1907. Records of the Department of Education indicate that the total number of Gabaldon school buildings constructed throughout the Philippines is 1, 852. However, there is no clear basis for classifying a Gabaldon school building. The current list presents a wide spectrum of types in terms of materials, planning, and design. The study seeks to develop a guideline for proper identification of Gabaldon school buildings by classifying typologies and relating them to historical context. Existing Gabaldon school buildings on the island of Cebu will be evaluated to determine patterns for which the Gabaldon school building may be defined. The result will be useful in assessing the significance of existing school buildings which were built during the American colonial period.
