We are following up to see if this program still exists. We will follow-up with another post once we have more information.
The “ThingWorx Badge” was associated with the retired ThingWorx Developer Associate exam. This has been replaced with the ThingWorx IoT Developer Specialization. This is on the new ptcu.com. Once you complete the required courses, you can purchase a Capstone exam to receive a ThingWorx IoT Developer Specialization Credential. Information about the training path and the Credential that can be found here.
