Degrees and Critical Skills the FBI Looks for with Job Applicants
For aspiring special agents, the FBI generally looks for applicants who have a bachelor’s degree in:
- Criminal justice
- Forensic science
- Cybersecurity
The FBI also requires special agent candidates to have critical skills, also known as core competencies. These critical skills include:
- Collaboration
- Communication
- Flexibility and adaptability
- Initiative
- Interpersonal ability
- Leadership
- Organization and planning
- Problem solving and judgement
Collaboration
One of the key skills that FBI special agents should possess is the ability to work as part of a team. FBI investigations often involve working with multiple agents, supervisory special agents, law enforcement partners, and people from other federal government agencies.
As a result, the ability to collaborate with others is essential. For instance, an FBI special agent might work with a behavioral science specialist to better understand a terrorist’s motivations.
Communication
Effective communication is crucial for special agents, who must convey complex information in a clear and concise manner. It may also be helpful if aspiring special agents can speak a foreign language, such as Spanish, Russian, or Arabic.
An FBI agent needs to communicate effectively with a variety of people. For instance, an agent may need to talk with fellow agents, law enforcement partners, and members of the public.
Additionally, an FBI agent may want to obtain information from victims, witnesses, suspects, and attorneys. FBI special agents must be able to adapt their communication style to different situations and audiences.
In addition to verbal communication, FBI agents must be skilled in written communication. For instance, they are often required to write reports or other documents as a part of their investigations.
Flexibility and Adaptability
The Federal Bureau of Investigation is responsible for investigating a wide range of crimes in different locations and environments. The ability to adapt to new situations and environments is essential for FBI agents, since that will impact their ability to successfully carry out their duties.
In addition, FBI special agents must work proactively. They should also be aware of different perspectives and be open-minded to information that other people provide.
Initiative
Occasionally, FBI special agents need to work independently and take the initiative when it becomes necessary. They should anticipate new projects, commit to continuous learning, and follow through so that the FBI’s goals are accomplished.
Interpersonal Ability
FBI employees must stay professional and maintain good relationships with various people, including their managers, colleagues, and subordinates. When disputes occur, they should be solved in a way that satisfies everyone and obtains future cooperation.
Leadership
FBI employees are expected to demonstrate leadership qualities, regardless of the title they hold. For instance, an FBI employee should inspire the respect of other workers by demonstrating integrity and credibility. Also, that employee can provide mentorship and guidance to other people.
Organization and Planning
FBI special agents must be highly organized with a strong focus on attention to detail and planning. Attention to detail is critical for special agents as they work to gather and analyze evidence, build cases, and identify potential suspects.
The ability to pay close attention to even the smallest detail or piece of evidence is an essential skill. For instance, a set of tiny fibers proved to be vital evidence in solving a Virginia serial killer case, according to ABC News.
FBI special agents also need the ability to prioritize tasks and develop plans. If there are problems, those problems should be quickly identified so that they can be resolved as soon as possible.
Problem Solving and Judgement
FBI employees must judge situations effectively, resolve problems by making recommendations, and manage risks. They should also demonstrate ownership of any problems and make decisions based on good judgement and sound reasoning.
