On the Symfony blog, there's a new post that introduces a new certification targeted towards the latest release of the framework: the Symfony 4 certification.
Symfony 4 was released in November 2017, alongside new best practices and Symfony Flex, the new way to manage Symfony applications. This new version is so different from Symfony 3 that we've decided to introduce a new Symfony 4 certification program.
The Symfony 4 exam consists of 75 questions to be answered in 90 minutes or less and you can take the exam in any of the 4,000 test centers available worldwide. The list of topics covers the most important parts of the core framework, excluding third-party libraries like Doctrine, Monolog, etc. Depending on your results, you'll get the Advanced Certified badge or the more difficult Expert Certified badge.
They already have the vouchers on sale for the certification so you can take it and add that certification badge to your list. You can find out more about this and other Symfony certifications on the Symfony project certification site.
