N.J. Stat. § 18A:60-3
Nothing contained in this chapter shall be held to limit the right of the commissioner, in the case of any educational institution conducted under his jurisdiction, supervision or control; or the Commissioner of Corrections, the Commissioner of Children and Families, or the Commissioner of Human Services, in the case of any State institution conducted under their jurisdiction, supervision or control; or of the board of trustees of a college, in the case of a college, to reduce the number of professors, associate professors, assistant professors, instructors, supervisors, registrars, teachers, or other persons employed in a teaching capacity in any such institution or institutions when the reduction is due to natural diminution of the number of students or pupils in the institution or institutions. Dismissals resulting from such reduction shall not be by reason of residence, age, sex, marriage, race, religion, or political affiliation. When such professors, associate professors, assistant professors, instructors, supervisors, registrars, teachers, or other persons employed in a teaching capacity under tenure are dismissed by reason of such reduction, those professors, associate professors, assistant professors, instructors, supervisors, registrars, teachers, or other persons employed in a teaching capacity having the least number of years of service to their credit shall be dismissed in preference to those having longer terms of service. Should any such professor, associate professor, assistant professor, instructor, supervisor, registrar, teacher, or other person employed in a teaching capacity under tenure be dismissed as a result of such reduction, such person shall be and remain upon a preferred eligible list in the order of years of service for reemployment, whenever vacancies occur, and shall be reemployed by the commissioner in such order, when, and if, a vacancy in a position for which such professor, associate professor, assistant professor, instructor, supervisor, registrar, teacher, or other person employed in a teaching capacity shall be qualified. Such reemployment shall give full recognition to previous years of service.
