There are a number of different safety threats that children face in their lives. One infrequent, but highly dangerous situation a child can face is finding a firearm. Hundreds of children are injured or killed by firearms each year. Fortunately, behavioral skills training (BST) and in situ training (IST) are effective approaches for teaching a number of different skills, including safety skills. The purpose of this study was to evaluate a teaching package for preschool teachers to learn to conduct BST to teach safety skills. A multiple baseline across subjects design was used to evaluate the effectiveness of this teaching package implemented by the teacher with seven preschoolers. Five children demonstrated the skills following in situ training and additional reinforcement or time out. Two children did not complete the study.
