Abstract The Minnesota Marking Attitude Scale was administered to 33 regular education and 20 special education teachers. Results showed that regular educators believed that marks have a positive influence on students while special educators believed marks have neither a positive nor a negative influence ( p < .005). Special educators believed to a greater extent than did regular educators that marks should be manipulated in order to influence student behavior ( p < .05) and that different standards should be used to evaluate different students ( p < .001). Teachers also marked students' written short answers to two typical school questions. No significant differences were found between the marks assigned by the two groups of teachers to either set of answers. Assigned marks, attitude scores, and years of teaching experience were not significantly correlated with each other. Results are discussed in terms of implications for mainstreaming.
