Joint effort included a nationally representative survey of 1,746 principals

To provide a comprehensive picture of BTAM implementation, the practices that schools are using to identify and manage potential threats to schools, and the potential solutions to strengthen BTAM across the United States, the joint HSOAC-NTAC research effort included a nationally representative survey of 1,746 principals across the country implementing BTAM practices at their schools.

Second limitation: findings may not fully capture variety across sizes, regions, and demographics

Second, although our survey aimed to be representative of administrators in K–12 public schools across the country, our findings may still not fully capture the variety of experiences across different school sizes, geographical regions, and student and community demographics.

Table 3.1 includes only schools with a BTAM team using a model and present at initial implementation

The table includes only those who said that their school has a school- or district-level BTAM team; their team was using a named model that we listed, an “Other” model, or a locally created one; and they were around for the initial implementation of this model.

Two analysis goals set before fielding; first: national estimates for principals and schools

Before going into the field, researchers identified two main goals for analysis. The first goal was to produce estimates that generalize to the national population of U.S. public school principals and the schools in which they serve.

Second goal: compare BTAM operationalization across three state policy contexts

The second goal was to facilitate comparisons in how schools operationalized their BTAM programs across three state policy contexts: (1) states that had early legislation (as of 2019), (2) states that encouraged BTAM use, and (3) other states.

Initial goal: 50 percent early legislation, 25 percent other states, 25 percent encouraged-only

Sample (no n: a percentage change, not a share of a sample) · a percentage that is not a share of a sample (e.g. a percentage-point change or a weighted estimate of the population)

The initial goal was to sample 50 percent from the early legislation states (as it was anticipated that BTAM programs would be most common in these states), 25 percent from each of the other states, and 25 percent from the encouraged BTAM use only states.

At a 30 percent response rate, sample 1,375 in other and encouraged states and 2,750 in early legisl

Sample (no n: a percentage change, not a share of a sample) · a percentage that is not a share of a sample (e.g. a percentage-point change or a weighted estimate of the population)

As shown in Table B.2, assuming a 30 percent response rate (which is in line with historical ASLP surveys), this would require sampling 1,375 principals in both the other states and encouraged BTAM use only states and 2,750 principals in early legislation states.

Too few panelists in other states; extra principals sampled from encouraged-only states

Sample (no n: a percentage change, not a share of a sample) · a percentage that is not a share of a sample (e.g. a percentage-point change or a weighted estimate of the population)

There were not enough panelists in the other states in the ASLP at the time of sampling to meet the desired sample. Therefore, we sampled some additional principals from the encouraged BTAM use only states to maintain the 50 percent/50 percent distribution with principals from early legislation states.

Sample (n = 1320 of 1650) · Targeted number of completed surveys (design target)

We anticipated that about 80 percent of the 1,650 completes would receive the full survey and be asked detailed questions about their BTAM program (n = 1,320) and 20 percent would receive the shorter survey (n = 330).
