N.J. Stat. § 18A:54-23.2
Any person desiring to enroll in a post secondary vocational-technical program in a county vocational school district as a nonresident student shall apply to the chief fiscal officer of his county of residence for a certificate of residence showing that said person is a resident of said county. The chief fiscal officer shall, upon application and submission to him of satisfactory evidence of such residence, issue said certificate provided that (a) the county does not maintain a vocational school providing such a program, or (b) the county vocational school district board of education certifies to the chief fiscal officer that it does not offer the particular course or curriculum desired by the applicant, or (c) the county vocational school cannot admit the applicant into a particular course or curriculum desired by the applicant pursuant to rules approved by the State Board of Education. If the chief fiscal officer refuses to issue such a certificate, the applicant may appeal to the board of chosen freeholders within 10 days of the receipt of notice of such refusal. The board of chosen freeholders shall hold a hearing on such appeal within a reasonable time, but not less than 10 days after notice is given to the chief fiscal officer and the applicant. The board of chosen freeholders shall notify the applicant of its decision within 10 days after such hearing.
