By July 1, 2019, the commissioner of education shall establish and encourage the implementation of a supplemental, 2-tier high school math program to be known as math learning communities, in order to meet the needs of any student who requires a better understanding of requisite math knowledge and skills and who has previously completed algebra I, but who lacks a strong foundation in mathematics to successfully transition from high school to college and career. Math learning communities shall be made available statewide to all public secondary schools. Students who would like to pursue a STEM career or postsecondary education program pathway but who are not ready to engage in mathematical reasoning and the application of math required in algebra II or other upper level math courses shall have access to this program of study and shall be encouraged to participate.
