ETA is committed to working with the government to ensure our certifications match the updated skills and knowledge needed to excel in various government or military positions. If you are a military professional and are looking for an additional way to build life-long skills that you can also carry with you into civilian life, get started with one of ETAâs more than 90 certifications. We create all of our certifications with the help of independent professionals from government, military, industry, and academic institutions. Under the G.I. Bill, the Veteranâs Administration can now reimburse you or an eligible child or spouse for many of the expenses for taking one of our approved certifications, and obtaining or renewing your FCC Commercial License.
