The impact of Dunn's article was enhanced by the prevailing sentiment
of the 1960s in favor of the environmental position and the press for
civil rights. The adoption of resource specialist services in place of
special day classes that was noted in the 1970s had profound curricul
ar implications, which are examined. The dramatic changes in the numbe
r of EMR students and the behavioral characteristics of those currentl
y identified render many of Dunn's assertions invalid for the current
situation. The current role of advocacy in policy formulation is discu
ssed as an unfortunate legacy of Dunn's influential paper.
