## Overview San Diego State University (SDSU) is a major public research university located in San Diego, California, recognized for its academic breadth, research impact, and vibrant campus life. As the oldest higher education institution in San Diego, SDSU is classified as an R1 research university—the highest distinction for doctoral institutions in the Carnegie Classification—and is also designated as both a Hispanic-Serving Institution and an Asian American and Native American Pacific Islander-Serving Institution (AANAPISI)[3]. ## History Founded on March 13, 1897, as the San Diego Normal School, SDSU initially focused on training elementary school teachers, opening its doors in 1898 with just 135 students[1][2]. It evolved into San Diego State Teachers College in 1921, began granting degrees, and moved to its current Mission Valley campus in 1931[1][2]. The institution was renamed San Diego State College in 1935 and, by the late 1950s, had become the fourth largest state institution in California[1]. On January 1, 1974, it became San Diego State University, reflecting its expanded academic mission[1][2]. The university’s enrollment peaked at nearly 36,000 by 1987, making it the largest university in California and the tenth largest in the nation at the time[1]. ## Key Achievements SDSU is distinguished by its rapid growth and academic evolution. It was among the first in the California State University system to establish professional schools and achieve accreditation in fields such as business, engineering, and health sciences[1]. The university is known for its international emphasis, direct faculty-student engagement, and a curriculum that prepares students for global careers[3]. SDSU’s research portfolio includes significant contributions in areas like public health, environmental science, and technology, supported by its R1 status[3]. ## Current Status Today, SDSU serves more than 39,000
