Horizon Monitorship

What is the Horizon Monitorship?

The Monitoring Team’s oversight of detained 16- and 17-year-olds began under the Nunez Consent Judgment, when youth charged as adults were housed on Rikers Island. Following New York’s enactment of the Raise the Age law, all 16- and 17-year-olds were transferred from Rikers Island to Horizon Juvenile Center, where operational responsibility gradually shifted from the Department of Correction to the Administration for Children’s Services (ACS).

The Horizon Monitorship stems from a voluntary agreement (Horizon Voluntary Agreement) entered into in November 2020 by the City of New York, ACS, and the Monitor (Steve J. Martin) concerning the operation of Horizon and the management and supervision of 16- and 17-year-olds deemed Adolescent Offenders housed at that facility. The professionals at Tillid Group were an integral part of the monitoring team that managed the implementation and compliance assessments of the agreement

During the term of the voluntary agreements, ACS demonstrated sustained and measurable progress, achieving compliance with additional provisions each year. As a result, the scope of provisions subject to ongoing monitoring steadily narrowed, reflecting the agency’s continued implementation of the agreement’s requirements and its progress toward institutionalizing the necessary reforms.

In the Monitor’s final report in November 2025, the Monitor found that ACS had achieved compliance with the three remaining substantive requirements of the agreement, and recommended completion of monitoring. In December 2025, the Court ordered that the Nunez Consent Judgment shall not apply to Adolescent Offenders going forward.
