Highlights of trends in campus police include: (1) more campus law enforcement agencies are using sworn and armed officers--during the 2004-05 school year, 74 percent of campus law enforcement agencies serving 4-year campuses with 2,500 or more students employed sworn personnel with full arrest powers; (2) campus police forces have become more diverse--in the 2004-05 school year, about 1 in 3 sworn campus officers were a racial or ethnic minority (31 percent); (3) substantial increases in training requirements for campus law enforcement officers were observed over the 10-year comparison period; (4) inflation-adjusted starting salaries increased 5 percent for sworn campus police officers; (5) campus law enforcement agencies improved emergency access systems on campus--percentage of students on a campus with emergency blue-light phones increased from 88 percent during 1994-95 to 96 percent during 2004-05; and (6) in 2004, campus law enforcement agencies received an average of 62 reports of serious violent crime per 100,000 students, about 9 percent fewer than in 1994. In 1995, to determine the nature of law enforcement services provided on college and university campuses, BJS surveyed 4-year higher education institutions with 2,500 or more students. An update to this survey was conducted for the 2004-05 school year offering an examination of 10-year trends in campus law enforcement. This report presents a summary of the comparison of the 1994-95 and 2004-05 BJS surveys. 6 tables, 6 figures
