N.J. Stat. § 18A:38-13
No such designation of a high school or high schools and no such allocation or apportionment of pupils thereto, heretofore or hereafter made pursuant to law, shall be changed or withdrawn, nor shall a district having such a designated high school refuse to continue to receive high school pupils from such sending district except upon application made to and approved by the commissioner. Prior to submitting an application the district seeking to sever the relationship shall prepare and submit a feasibility study, considering the educational and financial implications for the sending and receiving districts, the impact on the quality of education received by pupils in each of the districts, and the effect on the racial composition of the pupil population of each of the districts. The commissioner shall make equitable determinations based upon consideration of all the circumstances, including the educational and financial implications for the affected districts, the impact on the quality of education received by pupils, and the effect on the racial composition of the pupil population of the districts. The commissioner shall grant the requested change in designation or allocation if no substantial negative impact will result therefrom.
