Beginning in 2018, all VDOT materials certifications will have an Active lifecycle of five (5) years. At the end of this timeframe, the certification will become expired and its holder will be required to complete the same requirements as for a new certification to re-activate the certification. This includes the full course (classroom or online options are open to individual choice and/or availability), written exam, applicable proficiency exams and any prerequisite certifications.
Please note that pre-requisite courses for a higher-level course (i.e. Plant I and II for Mix Design) do not need to be completed prior to that course if those certifications are active. This means that you do not need to take Plant I or II before taking Mix Design if your Mix Design certification is coming due but your Plant I and II certifications are still active.
