Data Analysis
The program R Studio (version 1.4.1717) was used to evaluate inter-rater reliability using intraclass correlation analysis with a two-way random-effects model (irr package). Subsection and total scores for each district were calculated as the mean of the scores from the four raters. Total score distribution for district policies was assessed by a histogram generated in R. For each subsection and for total scores, median values with 1st-3rd quartile ranges were calculated and plotted using Prism (version 9). For individual criterion analyses, the percentage of policies that included a particular criterion was calculated for each rater. The mean and standard error for each criterion were calculated and plotted using Prism.
