July 30, 2026: NESHTA has been Dissolved


It is with a mix of gratitude, reflection, and optimism that I write to share an important update about the future of our organization. After thoughtful consideration and careful planning, the Board of Directors has made the difficult decision to dissolve the organization effective July 30, 2026, following nearly a half century of service.

The DDET and Master Certification Program will continue to run under the leadership of National PETE.
