For a couple years you have been requesting ESRI offer a certification program. And it looks like we are getting closer to having a ESRI Technical Certification program. See http://training.esri.com/certification/index.cfm
The ESRI Technical Certification Program is designed to establish a community of qualified individuals who are proficient in the best practices for using ESRI software.
Beginning at the 2010 ESRI International User Conference in San Diego, CA, beta testing of the exams for the ESRI Technical Certification Program will be open to ESRI Business Partners, International Distributors, Authorized Instructors, and ESRI employees. Release of the final exams to the general ESRI user community is targeted for 2011.
