Why does the Series 7 exam matter?
FINRA administers the Series 7 exam to enforce a minimum competency for entry-level employees. This is especially key for new hires who may not have had exposure to financial subjects in their university studies. The Series 7 acts as a prerequisite for many of the other FINRA exams, like those for options trading and managerial positions.
In 2018, FINRA rolled out the SIE (Securities Industry Essentials) Exam, another test required for new employees. The SIE tends to be a bit more basic in nature than the Series 7, which focuses on applying that knowledge in real-world situations.
