The after-school mathematics program was originally established in Boston,[3] inside Inessa Rifkin's living room.[4] Since then, RSM is one of the largest after-school math enrichment programs in the Northeast, and serves more than 15,000 students across eleven states and Canada, as well as in online lessons available worldwide.[5] RSM also runs an overnight camp in Sunapee, New Hampshire.

RSM has a somewhat major presence in the state of New York with all five locations located in New York City. The locations are RSM-Manhattan, RSM-Upper West Side, RSM-Downtown, RSM-Park Slope, and RSM-Brooklyn. The biggest location, RSM-Manhattan, serves nearly 900 students from the neighborhoods of the Upper East Side, Midtown East, and Sutton Place. It is located at 260 East 78 Street in the affluential neighborhood of Lenox Hill. This location also serves as the de facto headquarters for the state of New York. These branches all are and have been directly controlled by the central department in RSM-Newton as for every school in the system.

The RSM curriculum in the state of New York consists of three levels of difficulty, Accelerated, Advanced, and Honors. All students are put into the accelerated program when they first enter RSM. For their second year, they have the opportunity to move up to the advanced program. For students' third year, they have access to all levels of difficulty and are put into a class based on their grade average. This system is for Grades K-7. Starting in 8th Grade, students have the option to take different classes on different levels of difficulty. For example, a student can take geometry level 2, but also take calculus or Algebra 2 at level 3.

More than 4,000 alumni from New York RSM schools have gone to ivy league universities like Harvard, Yale, Cornell, and Columbia. Some also go to other top universities like University of Oxford, University of Cambridge, Stanford University, and so many others!
