Standard for
Recreation Vehicle
Service Technicians
Origin and Development of the RVST Standard
Since 1996 RVIA and the Certification Governing Board have been using the RV Service TechnicianDACUM Chart Job and Task Analysis as a basis for the certification exams and cirriculmn for RV
Service Technician Training. The DACUM is prepared by the National Occupational Competency Testing Institute (NOCTI) is America's foremost provider of high-quality written and performance occupational competency evaluation products and services.
Portions of the DACUM have been reformatted into a more user friendly format to create the RVST
Standard. The full DACUM is still used and available.
Statement on Development Procedures
The first edition of this standard is a direct excerpt of the DACUM and which has a thorough review
process outlined in that publication.
All questions or requests for information on obtaining formal interpretations, proposing amendments and appeals on matter relating to the contents of this document should be directed to the Vice
President, Standards and Education, RVIA, PO Box 2999, Reston, VA 20195-2999.
