More and more workers need professional training and licensure by a government to prove they meet certain standards before they can work in their chosen industry. Having such quality control in place is usually good for both professionals and consumers to ensure safe, quality work. Students considering any of the roles listed below often need official training or licensure in order to work at that job.

1. Pilots

Whether flying large commercial aircraft or smaller planes, pilots need to have training, licensure and time in the air in order to work. These professionals may need different, specific licenses for the type of commercial aircraft they wish to fly, such as helicopters or passenger planes. Unlike other occupations, which are usually governed on the state level, pilots are required to have a federal-level license from the Federal Aviation Administration in the United States.

2. Teachers

Public school teachers are almost always required to carry a teacher's certificate from the state in which they wish to teach. This certificate is obtained by going through training as a student teacher and often by passing an exam. Teachers do not always need an undergraduate or graduate degree in education, but they usually need a bachelor's degree in the subject they want to teach. College professors are often not licensed by the state but they must have graduate degrees and sometimes work experience as well.

3. Psychologists

A doctorate is required to become a psychologist in addition to other training. Internships are often part of a doctorate program, and psychologists need an additional couple years of supervised clinical training in order to get their license and work in a practice. Unlike psychiatrists, they are not medical doctors and cannot prescribe medications. They instead provide diagnosis for psychological disorders and use behavioral therapy and other techniques to help their patients live better, fuller lives.

4. Real Estate Agents

Real estate agents need a license from the state in order to work, which requires taking educational courses and passing an exam. This career is attractive because it pays on commission (meaning the more successful you are, the more you get paid) and does not require a college degree to get started. Real estate agents can choose to get additional certification as a Realtor, which comes with stricter standards but often improves job prospects.

5. Infrastructure Workers

Anyone who works in infrastructure, including electricians, insulation installers, engineers, elevator repairs and others, often either need a license, apprenticeship training or both. Requirements vary widely by region—in some jurisdiction a license may not be required at all while in others it might be more challenging to obtain. In some regions, a confined space ticket may be a very good idea or even required. This training covers daily, on the job work, in addition to safety procedures and how to respond in an emergency.

6. Attorneys

Lawyers must also complete training, in the form of graduating from an accredited law school, and pass the bar exam in their state to be allowed to practice law. They are held to rigorous standards both before and after earning their license as an attorney to uphold the integrity of a profession that runs on trust. Not only must they adhere to the rules of their bar association but also undertake continuing education training throughout their careers. They can choose to advance their careers after working in the field to become judges. This may require passing another exam and being elected to the position in which they wish to serve.

7. Certified Public Accountants

While not all accountants need training and licensure to work in the field, Certified Public Accountants, or CPAs, do. By law, only CPAs are allowed to file reports with the Securities and Exchange Commission in the US. Accountants become CPAs by taking a rigorous exam and becoming licensed by the Board of Accountancy in their state. Most accountants choose to earn this certification to improve their job prospects and professional prestige. It's also much easier to get your own clients and build a successful accounting firm with a CPA certification than without, if freelancing or owning your own business are goals for you.

Remember that training and licensing requirements differ between countries, states and local jurisdiction. Before embarking on an educational or career path, look up information on your chosen career and understand what requirements you must meet in order to legally work in that role. Once you know what is needed, you can get started on completing the necessary requirements.
