The purpose of this study is to find out the perception of early childhood behavioral problem and guidance strategies of prospective early childhood teachers as a fundamental study to establish basic data for program development suitable for understanding and guidance of behavioral problem. The subjects of the study were 112 pre-service teachers in the 2nd to 4th grades of the department of early childhood education at the University of N City. A survey was conducted to find out the perception of pre-service teachers about the type of early childhood behavioral problem and the importance of guidance strategies. Descriptive statistics, multi-variate analysis, and correlation were performed on the collected data. As a result of the study, first, pre-service teachers recognized [aggressive·anti-social behavior], [destructive behavior], and [obstructive behavior] as more problematic behaviors than [emotional·dependent behavior] and [avoidance of social behavior]. Second, in the case of the fourth grade, it was found that the perception of behavioral problem was significantly higher than that of other grades, and there was a difference in the perception of behavioral problem of children according to grades. Third, in recognizing the importance of guidance strategies on behavioral problem, [positive response strategies] were recognized as the most important, and all strategies except [negative response strategies] were found to be more important than ‘normal’, therefore, pre-service teachers recognized the need for teacher intervention and guidance as important. Fourth, in the case of 2nd and 3rd graders, the perception of [positive response strategy] was higher than that of [preventive strategy], but in the case of 4th graders, the perception of [positive prevention strategy] was significantly higher than that of other grades. Finally, as a result of examining the correlation between the pre-service teacher s perception of behavioral problem and the importance of guidance strategy, the perception of behavioral problem had no significant correlation with [preventive strategy], however, there was a significant correlation with [responsive strategy]. Therefore, it can be interpreted that pre-service teachers perceive that it is more important to use the [negative response strategy] after the behavioral problem occurs than to prevent the problem in advance. Based on the results of this study, it is possible to emphasize the need for a program that can strengthen the understanding of early childhood behavioral problem and expertise in guidance strategy in the teacher training process.
