Reports concerning children's behavior written by teachers contain the char
acteristics of the children as well as the implicit theories of the writers
. Therefore the reports may be marked as "portraits" with unclear validity.
In this study a content analysis of 66 reports describing mentally retarde
d children is carried out. These reports were written by expert teachers in
special education. A cluster analysis of the most frequent statements yiel
ded three different clusters, describing three levels of mental retardation
: mild, moderate, and severe or profound. Checkable data like age, school c
areer, medical diagnosis, and (in some respect) IQ confirm this conclusion.
The mildly retarded children are portrayed as relatively well adapted. The
reports of the moderately retarded children contain some specific restrict
ions. The portraits of the severely and profoundly retarded children emphas
ize the lack of self care. Conclusions concerning the procedures of educati
onal assessment are discussed.
