Biography
Professor (by courtesy) of Education
An accomplished clinical teacher and litigator, William Koski (PhD ’03) is the founder and director of the law school’s Youth and Education Law Project (YELP). He and the students in the law project have represented hundreds of disadvantaged children and their families in educational equity, disability rights, and school reform matters. Professor Koski and YELP are currently representing more than 60 students from across California in the pathbreaking Robles-Wong v. California lawsuit that seeks to reform California's dysfunctional and insufficient K-12 public school finance system.
Reflecting his multidisciplinary background as a lawyer and social scientist, Professor Koski’s scholarly work focuses on the related issues of educational accountability, equity, and adequacy; the politics of educational policy reform; and judicial decision making in educational policy reform litigation. Professor Koski’s current research concentrates on the normative case for and policy implications of ensuring equality of educational opportunity in the current context of educational standards, adequacy, and accountability.
Before joining the Stanford Law School faculty in 2001, Professor Koski was a lecturer in law at Stanford and a supervising attorney at the law school’s East Palo Alto Community Law Project. He was also an associate at Orrick, Herrington & Sutcliffe and then Alden, Aronovsky & Sax.
Professor Koski has an appointment (by courtesy) with the Stanford School of Education.
