Information is provided about the development of a teacher version of the Children's Behavior Questionnaire Short Form (CBQ Short Form; Putnam & Rothbart, 2006). The CBQ Short Form, designed for caregivers, was modified by changing the item wording for the preschool classroom and is termed the CBQ, Teacher Version (CBQ-T). Both measures were administered to the caregivers and teachers of preschoolers ages 3 to 6 years. The CBQ-T was found to be as reliable as the CBQ Short Form with two scales falling short of adequate internal consistency. Few correlations were found between parents and teachers in accord with literature documenting low to moderate agreement between the two raters. Several temperament scales were correlated with age for parents and teachers, none were correlated with gender as rated by parents, and several were correlated with gender as rated by teachers. Further validation of the CBQ-T with varying populations would be beneficial.
