Choice in American education remains one of the more important and cer
tainly more controversial issues in education reform movements. This a
rticle analyzes two types of choice programs located in the Milwaukee
metropolitan area. Numerous research issues are involved in the debate
s over educational choice. Two of the most important sets of issues ar
e who chooses and why, and what are the effects on educational outcome
s' This article is concerned with the first set of questions. The them
e of the article is that who chooses is a function of the type and des
ign of the choice program itself Although there are some similarities
in the characteristics of students and families in the Milwaukee Paren
tal Choice program (a private-school voucher program) and the Chapter
220 program (an inter-district public-school choice program), the cont
rasts are sharp and consistent across key variables. That result may n
ot be welcomed by those seeking simple and decisive conclusions concer
ning some general theory of educational choice. We, however, view it s
omewhat positively because the mes sage is that policymakers have the
ability to create different choice programs to address different probl
ems with appropriate effects on diverse student populations.
