Investopedia explains 'Series 51'
Even though many 529 plans contain equity-based fund options, they are still regulated under the arm of the MSRB. The Series 51 was established for principals who do not otherwise deal in municipal securities, and do not have the Series 53 designation. Exam topics will test the taker's knowledge of underwriting, sales office supervision, market terminology and fair practice rules.
