Individual Criterion Analysis
To obtain an even more granular assessment of policy content, the percentage of policies including each criterion was calculated (Figure 3). The mean percentage of inclusion in policies was less than 20% for most criteria. Percentages were even lower for re-entry and postvention. The plot revealed two outlier criteria, one in the prevention and one in the intervention subsections. Most district policies indicate how often professional development courses on suicide prevention are required (Pr-4) and include a protocol for parental notification in the event of a suicide (I-6).
