I was denied certification; I was told that because I already have a certification in another career field, I could not use the same experience to obtain this certification. Where is this policy written?

Per the DACM Office’s “Defense Acquisition Workforce Improvement Act Certification Policy for the Army Acquisition Workforce”, the same months of specialized experience used to obtain certification in one Acquisition Functional Area (AFA) may not be applied to meet the specialized experience standards in an additional AFA. For a copy of this policy, please see the DACM Policy Library at https://asc.army.mil/web/alt-workforce-policy-procedure/.
