The charter school movement gained considerable momentum during the ea
rly 1990s in the United States. This paper provides an overview of the
charter school phenomenon and begins with a consideration of the basi
c design of these schools. The government's role in education is discu
ssed and various school choice options are identified. The paper then
focuses on the degree of overall autonomy granted to charter schools b
y examining the basic features of various state legislative provisions
that permit charter schools. The limited empirical work available is
reviewed to present a clearer picture of charter schools with regard t
o school autonomy and innovation, teacher and student characteristics,
and parental contracts and involvement. Several concerns are presente
d about charter schools relating to autonomy and regulation, market ac
countability, and at-risk students. Copyright (C) 1997 Elsevier Scienc
