In this article, the authors examine the psychometric properties of the "Student Risk Screening Scale" (SRSS) for use in urban middle schools. Results of Studies 1 and 2 suggest strong internal consistency and test-retest stability. Study 1 supports the predictive validity of the SRSS, with students at low risk being able to be differentiated from moderate- to high-risk status on behavioral and academic measures. Study 2 also supports predictive validity up to 2 years following initial SRSS status, with students in the low-risk group having significantly fewer out-of-school suspensions, fewer unexcused absences, and higher grade point averages than students in the moderate- and high-risk groups. In addition, results of Study 1 support the feasibility of the SRSS, with increased use over time serving as a behavioral marker for social validity. Limitations and implications for future research are discussed. (Contains 8 tables.)
