This study investigates what grade-3 teachers say they would do if faced with common test administration dilemmas--and why. Grade-3 teachers with experience administering Ontario's provincially mandated assessment were recruited through professional association newsletters and Toronto-area newspapers. They responded to an on-line questionnaire (n = 98) or an hour-long interview (n = 40). Many teachers predicted that they would not follow the test administration instructions. Their rationales included (a) supporting the students to do their best work, (b) ensuring a positive testing experience for the students, and (c) maintaining their pedagogical routines and their relationships with the students. The findings highlight the ethical dilemmas teachers may experience when proctoring tests. (Contains 1 footnote.)
