The purpose of the present study was to compare Thai and Korean college students on their perceptions of the roles and functions of school psychologists. One hundred and ninety-three Thai college students and 238 Korean counterparts participated in this study. Students rated the importance of various roles/functions of a school psychologist and specified who should assume those roles/functions in the absence of a school psychologist. Results indicated that Thai education students rated the roles/functions of counselling students, intervention, consultation with teachers, and consultation with parents, significantly higher ("p"<?0.01) than their Korean counterparts. However, there was no significant difference between the two groups on the assessment role ("p">?0.05). Thai students expected their relatives and school personnel and other related people outside of the schools to fill in the vacuum of a school psychologist significantly ("p"<?0.01) more than their Korean counterparts did in all roles and functions.
