The purpose of this study was to develop a new measure of preservice early childhood teachers’ sense of efficacy. Based on Bandura’s (1977, 1997) self-efficacy theory, exploratory and confirmatory factor analyses resulted in the development of a 18-item, 4-factor Preservice Kindergarten Teacher Efficacy Scale [PKTES] which produced scores with acceptable validity and reliability. The four factors of the scale are effective teaching, professional knowledge/skills, coping with family influence, and coping with social influence and child characteristics. The preservice early childhood teachers’ sense of efficacy is significantly different in relation to grade level and preparedness to teach.
