The extremely popular “CSI” TV series has resulted in a surge of interest in crime scene investigator careers among recent high school graduates. Although the real-life job is less glamorous and dramatic than depicted on TV, it is a crucial aspect of the justice system that is becoming increasingly valuable with the explosion of technological and scientific advances.
CSIs can be either law enforcement officers or civilians. They are employed by city police departments, county sheriff’s departments, the FBI, the attorney general’s office, insurance companies, law firms and others. The Bureau of Labor Statistics (BLS) indicated that, as of May 2011, there were over 12,500 CSIs employed in the U.S. with a predicted 19 percent increase, or another 2,400 CSI jobs, by 2020. In 2011, 1,730 of these CSIs were employed in California with 70 CSIs working in San Diego, 100 in Sacramento, 260 in San Francisco and 520 in Los Angeles.
According to the U.S. Bureau of Labor Statistics, the average mean salary for CSIs in California is $72,000. The breakdown for some large cities is:
- Sacramento: $61,720
- Los Angeles: $79,220
- San Francisco: $80,860
Requirements for Becoming a Crime Scene Investigator in California
The following requirements are usually required for a job as a CSI in California. However, different agencies/departments or locations may not require all of them.
Education – The right education is the most important requirement for a successful career as a CSI. Some California schools offer a certificate in crime scene investigation that usually involves 20 credit hours in such relevant courses as:
