Security Consultants and Guards
A high school diploma is preferred for security guards and required for security consultants, who should also go on to obtain a college degree. Security guards must be high school graduates. In addition, they should expect to receive from three to six months of specialized training in security procedures and technology. If you would like to be a security guard, you should take mathematics courses while in high school to ensure that you can perform basic arithmetic operations with different units of measure; compute ratios, rates, and percentages; and interpret charts and graphs.
