Relations between parents of children with developmental disabilities and o
ther community members on agency boards can be difficult to negotiate. In t
his comparative study of the boards of three community agencies, we examine
d the forces that influence the quality of parent-community member relation
s. The results suggest that when differences between groups are acknowledge
d and respected at the same time that similarities are recognized and value
d, board operations are more likely to be successful and focused on providi
ng effective services. The case descriptions included here suggest that an
organization's ability to manage the tension between intergroup differences
and similarities is influenced by (a) organizational history of intergroup
relations, (b) group identification, and (c) organizational practices that
bridge group differences. Action implications are discussed.
