The MSRB is publishing this notice to announce that it plans to revise the Municipal Securities Representative Examination (Series 52) into a specialized knowledge exam in advance of the October 1, 2018 release of the FINRA's Securities Industry Essentials™ (SIE) examination. The MSRB worked collaboratively with FINRA during development of the SIE examination to streamline duplicative testing of general knowledge that has traditionally been covered across several representative-level examinations. The MSRB supports the goal to reduce testing redundancies for securities industry professionals and expand opportunities for prospective securities professionals. To that end, the MSRB anticipates filing a proposed rule change with the Securities and Exchange Commission in early 2018 to require the SIE as a prerequisite to registration as a Municipal Securities Representative, Municipal Securities Sales Limited Representative and Limited Representative-Investment Company and Variable Contracts Product Representative.
