Claims about Subgroup Differences

More specifically, we examined differences in educators’ responses based on six school characteristics: (1) grade levels served, (2) school locale, (3) school neighborhood poverty status, (4) student racial/ethnic composition, (5) school enrollment size, and (6) district enrollment size.

Three state categories help show whether early encouragement might relate to practices and outcomes

Grouping states into the three aforementioned categories allowed us to understand whether early encouragement or legislation by states to implement BTAM in schools (potentially associated with stronger funding, training, or other support for BTAM) might be related to the practices and outcomes reported by principals today.

2019 grouping still useful to show how early state support may have affected BTAM implementation

Nevertheless, understanding the implementation of early legislation by some states in 2019 is still useful for the purposes of this current analysis, insofar as it helps demonstrate how early state support in 2019 may have affected BTAM implementation over time across different state policy contexts.

Schools in states with no 2019 legislation or encouragement more likely to use a BTAM-like team

schools in these states are more likely than their counterparts in other policy contexts to use a BTAM-like team to perform threat assessment and management functions (e.g., an MTSS or PBIS team).

With the caveat that principals in large districts were more likely to report not knowing about the specific actions their school or district took in the lead up to BTAM implementation, principals’ reports suggest that small districts (those serving fewer than 10,000 students) approached adoption somewhat differently from large districts (see Figure 7.2).
