The NATE Ready to Work Program is designed to cultivate new technicians into the industry with all the essential skills needed to start a career in HVAC. There are no prerequisites. Successfully completing this program with a grade of 70% or more provides you with your OSHA 10 hour safety card (included); and you are prepared for your first NATE Ready-to-Work (RTW) Certificate Exam. Students can move through course material more quickly or take the full 60 days per course, as they choose.
