Built in 1906, it is named for Martin Grove Brumbaugh, the 26th Governor of Pennsylvania and an influential educator who headed Puerto Rico's school programming after the U.S. ousted Spain.

It retains most of its original physical features, including its structure, spatial relationships, proportions, and construction materials.

The Dr. Martin G. Brumbaugh Graded School is of statewide significance under Criterion C for Architecture, as it represents early twentieth-century construction methods for educational facilities in Puerto Rico, harmoniously combining three distinct construction periods.

The property is also significant under Criterion A for Social History as a prime example of the early U.S.-led social initiative in Puerto Rico, which promoted education alongside a political agenda of Americanization and cultural assimilation throughout the island.
