Amends GS 115C-81.36, concerning advanced courses in mathematics, as follows. Requires charter schools, in addition to the already listed local boards of education, to offer advanced courses in math in grades three and higher when practicable. Requires, when advanced math courses are offered, any student scoring at the highest level (was, scoring a level five) on the end-of-grade or end-of grade test for math to be enrolled in the advanced course for the next math course in which the student is enrolled; makes the same changes for seventh grade students whose next level course will be at a high school level. Allows local boards of education to administer diagnostic assessments upon enrollment in the high school level math course to provide identified students with supplemental content enrichment. 

Requires the Department of Public Instruction (DPI) to report annually, beginning October 15, 2019, to the specified NCGA committee on data collected on students eligible for advanced math courses and information as to how many were and were not placed in advanced math courses. Specifies information to be included in the report.

Requires DPI to provide guidance to local boards of education and charter schools on how to best develop programming and courses to ensure that all impacted students receive rigorous, academically appropriate instruction in mathematics.

Makes conforming changes to GS 115C-218.85.

Applies beginning with the 2019-20 school year.
