This First Look report presents selected findings about student financial aid during the 2017--18 academic year. These findings are based on data from the 2017-18 National Postsecondary Student Aid Study, Administrative Collection (NPSAS:18-AC). NPSAS:18-AC is a national study of undergraduate and graduate students enrolled any time between July 1, 2017 and June 30, 2018 in institutions that can participate in federal financial aid programs. It is also a special Administrative Collection that was conducted in 2017-18 in which only administrative data from the U.S. Department of Education's data systems, institution student records, and other national administrative data sources were compiled to yield state representative data. Data were collected between July 2018 and September 2019. The main purpose of NPSAS:18-AC is to measure how students and their families pay for postsecondary education. Specific focus is placed on federal student aid given through Title IV of the Higher Education Act. Data used in this report are from about 245,600 undergraduate and 21,300 graduate students attending 1,900 institutions in the 50 states, the District of Columbia, and Puerto Rico. The sample represents about 16.6 million undergraduate and 3.6 million graduate students enrolled at Title IV eligible institutions at any time between July 1, 2017 and June 30, 2018.
