The aim of the present study was to examine the attitudes of Greek school teachers on the inclusion of students with special educational needs as well as the factors that may influence their attitudes (positive or negative). The sample of the survey consists of 120 (48 male and 72 female teachers) school teachers (Kindergarten and primary schools) from rural and urban areas of Northwest Greece. Research data was selected using the Greek version of ATIE scale, developed by Wilczenski (1992; 1995) and standardized in Greek by Tsakiridou & Polyzopoulou (2014). The results of the survey showed that school teachers generally are in favor of including students with SENs, although their perceptions differ significantly based on some demographic factors.
