I'm thinking about getting an Adobe ACE certification for Flex, but found some stuff on Adobe's site confusing. What I'm interested in, is a certification that gives me a credential which shows I'm proefficient in Adobe Flex(for employer/work), I'm not sure which of the multiple available tests offers me that.
For example, on this page(http://www.adobe.com/support/certification/developer.html), if you scroll down to the "About Flex Developer Certification" section, it says you need to do the 9A0-129 test to become an ACE Flex developer, but on this page(http://www.adobe.com/support/certification/exams/) that particular test isn't listed at all, but 9A0-182 and 9A0-082 are.
Does taking any of these tests get you an ACE certification in Flex?
It seems like they had changed 9A0-129 to 9A0-182: Flex 4.5 ACE Exam
I took the exam on oct 11 2010, at that time it was 9A0-129, after seeing your question i went and check in Pearson Vue (by logging in with my account), I noticed that its changed to 9A0-182.
So taking 9A0-182 will definitely get you Ace certifaction in flex 4.5.
Hope this helps.
