House committee substitute to the 3rd edition makes the following changes.

Further amends GS 115C-81.36 to no longer require students in seventh grade scoring at the highest level on the seventh grade math end-of-grade test to enroll in a high school level math course in eighth grade. Removes the proposed provision which allowed local boards of education to administer diagnostic assessments upon enrollment in the high school math course to provide supplemental content enrichment. Changes the initial reporting requirement of the Department of Public Instruction from December 15, 2019, to December 15, 2020, and specifies that the annual report must contain data collected for the current school year on students eligible for advanced math courses and whether or not they were placed in the courses (previously, did not specify the year the data is to reflect).

Adds a new requirement for local boards to develop a plan to implement the provisions of GS 115C-81.36(b), as amended, concerning advanced math placement in grades six and higher, to be submitted to the Superintendent of Public Instruction (Superintendent) by January 15, 2020. Details information that must be included in the plans, including a list of each advanced math course offered, an explanation of advanced math course staffing, and an estimate of the expected enrollment increase in the courses for the 2020-21 school year, as specified. Requires the Superintendent to compile the plans submitted into a summary report to be submitted to the specified NCGA committee by March 15, 2020. 

Specifies that local boards are not required to comply with GS 115C-81.36(b), as amended, for the 2019-20 school year.
