We asked those principals involved in the initial implementation of a specific BTAM program and who perceived that the BTAM program was working effectively at their schools how long it took them to get the BTAM program to the point of “working well.”
Sample (N = 439) · Appendix A table base (respondents answering the table question; see note for tables)
Most principals said it took between one and two school years to get to that point, while 38 percent said it took one school year, 40 percent said it took two school years, and 11 percent said it took three or four school years.
Sample (N = 439) · Appendix A table base (respondents answering the table question; see note for tables)
Eleven percent were not sure how long it took for their teams to become effective.
That is, we examined the time to effectiveness for the different cohorts of BTAM adopters as shown in Figure 3.2.
Sample (column N undeterminable) · Earliest adopters (BTAM team in place 9+ years)
Looking at the earliest adopters (those schools that adopted BTAM teams nine or more years ago), 93 percent perceive that their BTAM teams are at the point where they are somewhat or very effective at maintaining school safety.
Sample (column N undeterminable) · Earliest adopters (BTAM team in place 9+ years)
Only 23 percent of these earliest adopters report that they had reached effectiveness within the first school year.
Within two school years, most early adopters said they feel that their BTAM teams were somewhat or very effective at main-

This figure depicts response data from the following survey questions: “How effective do you believe this BTAM team is at maintaining school safety?” “Approximately how many school years has this BTAM team been in place?” and “How long has your school used [AUTOFILL] program?” (n = 441).

taining school safety; within four school years, three-quarters said they feel they have reached effectiveness.
Sample (column N undeterminable) · Earliest adopters (BTAM team in place 9+ years)
Among these early adopters, 12 percent of principals said they feel that their schools had reached the point where the BTAM team was somewhat or very effective at maintaining school safety but were not sure how long it took the team to get there.
For schools that adopted BTAM more recently, enough time may not have passed yet for schools to overcome any initial implementation challenges such that their teams are functioning effectively.
Sample (column N undeterminable) · New adopters
Among the newest adopters, 60 percent of principals perceive that their BTAM teams have become somewhat or very effective at maintaining school safety.
Sample (column N undeterminable) · New adopters
Among the balance, 15 percent feel their teams are not currently effective, and 25 percent were not sure whether their BTAM teams were effective.
We also examined how long it took for principals to perceive that their schools’ BTAM teams were effective based on when their BTAM program was implemented.
When we asked principals who had played a role in establishing their school’s BTAM program questions about the initial implementation phase, most indicated it was relatively smooth and that their program became an effective contributor to safety at their school relatively quickly.
