Case management services under NYS PROMISE are provided by a robust and diverse network of case managers and family coaches. Case managers work predominantly with youth in the research demonstration sites, while family coaches work exclusively with the families of intervention group youth enrolled in NYS PROMISE through regional Parent Training Centers. Regardless of the title of the practitioner, or their organizational placement, they provide similar critical care, coordination and access to the core services and supports provided under the NYS PROMISE intervention, as well as information and referral for other needed services and supports. In addition, they provide intermittent "light touch" data gathering on control group youth and families. While "field guides" have traditionally been employed in the study of plants and fauna, they have increasingly been created to support practitioners in an array of professional fields as they face the obstacles and challenges that can arise while accomplishing specific tasks. The NYS PROMISE Case Management Field Guide was designed for the express purpose of assisting case managers and family coaches in navigating their day-to-day roles, functions, and expectations, while adhering to high quality standards, and managing the impact of their work on their own health and wellbeing. The aim is to ensure that all NYS PROMISE case managers and family coaches (case management practitioners) are equipped to perform their job in a manner that leads to the expected youth and family outcomes of the NYS PROMISE intervention--holding to a common measure of fidelity. This field guide is presented in modules and is indexed to assist case management practitioners in easily accessing the information they need, when they need it. The following modules are included in this field guide: (1) Overview of Case Management; (2) Service Delivery; (3) Youth in Transition; (4) Self-Determination; (5) Case Planning and Service Coordination; (6) Case Recording; (7) Counseling Resources; (8) Crisis Management; (9) Engaging Families; (10) Protection and Advocacy; (11) Triaging Benefits and Entitlements to Support Career Development and Work; (12) Justice-Involved Youth; (13) Community Participation; (14) Emerging Adulthood; and (15) Closeout Process for PROMISE.
