The opening of the Wesleyan University-Philippines Graduate School was the brainchild of Dr. Roxy Lefforge, the institution’s third President. It was conceived shortly after she assumed office in 1952 in collaboration with some Methodist members who saw the need to offer an advance course in Education. Operation of the Graduate School started during the second semester of A.Y. 1952-1953 with thirty students. Today, the School of Leadership and Advanced Studies (SOLAS) stands as a hallmark of higher education in this part of Central Luzon and is the oldest Graduate School in Region III.
In A.Y. 2021-2022, WU-P implemented a verticalization of its degree programs. Hence, several programs at the Graduate School were transferred to various Colleges. At this time, SOLAS focuses on leadership, administration, and other innovative degree programs that seek to equip responsible citizens who play important regional, national, or global roles.
