This brief describes how to use a free online behavior screener to identify student support needs in middle and high schools. Inclusive Behavior Instruction utilizes data to identify appropriate social-emotional supports for all students. The Lane et al. (2016) study demonstrated system-wide use of a free online behavior screener at the middle and high school levels to identify needs. The authors also demonstrate how to map out current supports and determine which to use based on the collected data. The authors concluded with the importance of guiding school leaders to: (1) ensure teachers are trained in the application of any behavior screening tool, how to score the tool, and how use the resulting data; (2) check local laws on systematic behavioral screening; and (3) fully inform families of the purpose and use of these data.
