It's been a long time, but Delphi certification has returned for those who want to prove their prowess over the Win32 development tool.
If keen, your main port of call should be the Embarcadero Certification Center. Here you'll find information about the two levels of certification on offer.
Firstly there is the basic Delphi Developer Certification that tests general knowledge of Delphi syntax, programming techniques, the IDE and database development. Those who have a registered copy of Delphi XE or RAD Studio XE can take this certification test for free (if they request a test code before the end of July 2011 and use it within 90 days). For others it will cost $US49. It would be advisable to check out the Delphi Developer Certification Exam Study Guide before taking the test, which can be taken online.
There is also the Delphi Master Developer Certification, which tests more advanced knowledge of Delphi concepts, architecture choices, syntax, techniques, IDE, projects and groups, component use and development, client/server, Internet and multitier development. This test needs to be taken at a Certification Center and will cost $US149. There is also a Delphi Certified Master Developer Exam Study Guide to check out before taking the test.
