Introduction: In 2019, the "Workplace Suicide Prevention and Postvention Committee" launched the "National Guidelines for Workplace Suicide Prevention," garnering nearly 2,000 pledge partners. Recognizing the need for a comprehensive approach, the committee introduced the "H.O.P.E. Certification" in 2021, offering a year-long program aligning with the National Guidelines. Grounded in 8 principles and 9 practices, the certification aids organizations through training and recognition, bestowing "Bronze," "Silver," "Gold," and "Platinum" certificates. Methods: In 2022, the Suicide Prevention Center of New York (SPCNY) started the first pilot implementation with the construction industry. In 2023, Colorado’s Office of Suicide Prevention funded a pilot program that enrolled five organizations (three construction and two healthcare) in a second pilot. Between the two pilots seven organizations representing between 35 and 10,000 workers were led by teams of 5-10 people each. Over the course of 12 months, the teams completed four 6-hour workshop modules and then produced deliverables related to each of the 9 practices. The Evergreen Certification group then reviewed the deliverables and awarded the appropriate level of certification. The pilot efforts were evaluated by Research Evaluation Consulting and a research team from Texas State University with pre- and post-measures after the Summit and each module. Community impact was also evaluated. Results: For the New York State Pilot, the biggest challenges in implementing the H.O.P.E. certification were buy-in from employees, lack of time, and funding. Four global constructs were compared over time: Understanding Benefits , Knowledge about Content, Confidence in , Intention to Share.Preliminary results from the Colorado pilot reveal that 100% of attendees were satisfied or very satisfied with the Summit. Time and resources were identified by most attendees in the pre-survey as a barrier to organizational success in developing and implementing a comprehensive and sustainable mental health promotion and suicide prevention strategy. In the end, 76% of participants shared with 10 or more people what they learned. Conclusions: The H.O.P.E. Certification is the first of its kind to attempt to implement the National Guidelines for Workplace Suicide Prevention. The New York and Colorado pilots provide key insights for the implementation of future pilot efforts in other states, large companies or unions, or with insurers.
