N.J. Stat. Ann. § 52:17B-171.3

3. Between 24 and 48 hours following admission to a county juvenile detention facility, a juvenile shall undergo mental health screening using a mental health screening tool designated by the Youth Justice Commission and in accordance with the facility's written policies required by section 1 of this act. If the screening tool indicates that a referral for additional screening or mental health services is appropriate, that referral shall occur as soon as possible. If the screening indicates a warning or caution, the juvenile shall be placed on, and remain under, increased supervision until it is determined by a mental health clinician that a heightened level of supervision is no longer needed to ensure the safety of the juvenile.
