Validity refers to the extent to which a given study reflects the dominant values of a research community regarding what constitutes "good" research. Methodological texts on qualitative research provide a wide range of criteria and strategies to help qualitative researchers validate their studies. Given the importance of these strategies to establish a study as trustworthy and legitimate, the objective of this study was to understand the strategies commonly used by school psychology researchers in qualitative research. We therefore reviewed qualitative research articles published in seven school psychology journals between 2006 and 2021. We found 15 strategies authors used to enhance the validity of their research. We also found that a strategy could be enacted in many different ways by different researchers depending on the context. We conclude by recommending four ways in which qualitative researchers in school psychology can improve their validation practices.
