The ninth section of SSOCS, entitled "School Characteristics," asks respondents about the structural characteristics of the school campus and features of the student body. Variables include total enrollment, English proficiency, percentage of students eligible for free or reduced-price lunch, percentage male enrollment, typical number of classroom changes, level of crime where the school is located and in the areas where students live, and the number of student transfers in and out of their particular school. Correlating these characteristics with incidence of crime and safety practices will assist in developing targeted efforts to address the specific needs of schools.
