The Washington Assessment of Risks and Needs of Students is a youth self-report screening instrument developed for use by high school and juvenile court personnel faced with the legal and practical challenges of high truancy and dropout rates. It purports to measure six facets of risks and needs of youth relevant to improving school outcomes. In this study, a bifactor model measuring a general factor and six specific factors was examined for fit and invariance across different groups defined by sex and race/ethnicity, with a sample of court-petitioned high school students (N = 937; ages 13-17 years). The results of multigroup confirmatory factor analysis revealed an essentially invariant bifactor structure across the groups. Further analysis of reliability support the use of the general factor to guide decision making for youth at risk for truancy and school failure, and scores deriving from the six specific factors as providing insight on specific areas of risk and need.
