Astin received his A.B. degree in Music from Gettysburg College in 1953 and his Master of Arts and Ph.D. in Psychology from the University of Maryland in 1958. Astin has been director of research for both the American Council on Education (1965–1973) and the National Merit Scholarship Corporation (1960–1965).

He has also been elected to membership in the National Academy of Education (NAEd), a fellow at the Center for Advanced Study in the Behavioral Sciences at Stanford University, and a recipient of eleven honorary degrees. A 1990 study in the Journal of Higher Education identified Astin as the most frequently-cited author in the field of higher education. A 2010 study in the same journal also identified him as the author most cited by others in the field of higher education. In 1985 readers of Change magazine selected Astin as the person "most admired for creative, insightful thinking" in the field of higher education. His latest book is Are You Smart Enough? How Colleges' Obsession with Smartness Shortchanges Students (Stylus, 2016).

Astin was born in Washington, D.C. to the late Margaret Linnie Mackenzie and Allen V.

After retiring from active teaching in 2002, they coauthored a major national study on spirituality in higher education, which became available in book form in 2011.^[5] The Astins have two sons, John Alexander (Doctor of Psychology) and Paul Allen (Doctor of Education), and three granddaughters, Erin, Amalia and Ila.^{[citation needed]}
