Employment data were collected from personnel files of 43 teachers of students with serious emotional disturbances from a large suburban school district. The 43 records were sorted into groups by level of college education and type of teaching endorsement. The groups were then compared for differences in duration of employment and summative evaluation scores on the Texas Teacher Appraisal System using a non-parametric one-way analysis of variance. At a .05 probability level, no significant differences were found between groups.
