How to Become a Criminal Investigator in Texas with an MS in Criminal Justice

For those considering a career in criminal investigation, the process often involves a combination of experience, formal education and specialized training. Graduates of the online Master of Science in Criminal Justice program from Lamar University are prepared for high-level staff, administrative, management and planning jobs within criminal justice agencies.

Texas is a hub for criminal investigation, with 16,810 investigators employed across the state. This number is the second highest nationally, and the job market is projected to grow by 6%, which is faster than the national average. The state’s large population and its crime rate of 37.4 incidents per 1,000 residents create a constant need for qualified professionals.

The traditional route to becoming an investigator begins with service as a police officer. This role provides the hands-on training, experience and familiarity with police procedure necessary for advancement. New officers need to complete training at a police academy and become licensed through the Texas Commission on Law Enforcement (TCOLE). After a period of service, typically a few years, a patrol officer can apply for a detective position within their department. The progression from officer to detective often involves an internal selection process that considers an officer’s service record, performance on the job and additional training.

The Value of Advanced Education

While a high school diploma is the minimum requirement to become a police officer, higher education is becoming increasingly important to advance one’s career. Many agencies prefer candidates with an associate’s or bachelor’s degree. For those who want to stand out and work in positions of leadership, having a master’s degree in criminal justice is an advantage.

Lamar University’s online MS in Criminal Justice is a good fit for working professionals. Its online format provides flexibility, allowing students to continue their careers while earning an advanced degree. The curriculum is relevant to the duties of an investigator, preparing them for the demands of the job.

The median salary for criminal investigators in Texas is $89,394, but a master’s degree can help professionals move into higher-paying roles, including supervisory and administrative positions. The earning potential is substantial, especially when combined with experience.

Career Tracks for Investigators

There are three primary career tracks for investigators: state-level law enforcement, federal agencies and private investigation. Each track has its own requirements.

  • State law enforcement: For investigators in Texas’s state and local agencies, advancement is tied to rank and tenure. Promotion from detective to sergeant or captain often requires a combination of years of service, strong performance and a higher level of education. A master’s degree in criminal justice can be an important credential for these opportunities. TCOLE provides continued education for active officers, including courses in criminal investigations, crime scene analysis and criminal law updates. These courses help officers maintain their licensure and stay current on investigative methods.
  • Federal agencies: For those who want to work for federal agencies such as the Federal Bureau of Investigation (FBI) or Immigration and Customs Enforcement (ICE), a bachelor’s degree is a general prerequisite, and a master’s degree can be beneficial. These agencies operate on a different scale, often dealing with more complex cases and requiring applicants to demonstrate high levels of analytical ability and specialized training. An MS in Criminal Justice can help an applicant meet these standards.
  • Private investigation: Becoming a private investigator in Texas requires a license from the Texas Department of Public Safety (DPS). The Texas Association of Licensed Investigators (TALI) promotes professional standards and provides resources for its members. The requirements for a private investigator license include a combination of education and experience. This may involve a bachelor’s degree, an associate degree with investigative experience or a specified number of years of experience in the field. Unlike public law enforcement, private investigators often work for individuals, businesses or legal teams.

The variety of career options and Texas’s favorable job market make the state an appealing place to work in criminal investigation. An advanced degree can open doors to roles that have greater responsibility and higher salaries in both the public and private sectors.
