This article examines interactions between the policy environment and schoo
ls as institutions to understand how eight middle and high schools in Calif
ornia responded to demands to improve student reading. The authors argue th
at school-level reading programs were shaped by the broader institutional e
nvironment: institutional norms that govern conceptions of appropriate role
s and responsibilities, technical components of the middle and high school
curriculum, and the limitations posed by resource constraints. The authors
consider the state curriculum policy an impetus for schools to focus on rea
ding development but insufficient to overcome these other important constra
ints. At the same time, the authors contend that the organization and alloc
ation of resources to support instruction made important contributions to r
eading development. This article uses data from case studies of eight middl
e and high schools located in six school districts in California.
