This study examines placement patterns in New York, Louisiana and New
Jersey to determine why these states place nearly half of their studen
ts with disabilities in separate classrooms, when most states place th
e vast majority of students with disabilities in general classrooms. U
sing regression analysis and interviews, several factors were examined
including the influence of the states' prior practices and policies,
economic and social variables, the consequences of state-finding formu
las, and the effectiveness of federal monitoring. New York Louisiana,
and New Jersey have maintained a high proportion of separate placement
s regardless of disability for longer than most states. Each of these
states has a large percentage of African American students and of stud
ents from poor families. Each of these stares provides fiscal incentiv
es for segregated placements. Federal monitoring is ineffective; the U
.S. Department of Education is slow to act on placement variability ac
ross the states.
