Preparing for the Exam

Achieving recognition as a Liferay Certified Professional Back-End Developer demonstrates that you understand core concepts for developing Liferay modules and know how to follow Liferay best practices to develop robust, elegant, and maintainable solutions based on the Liferay Platform. The exam is designed to be challenging, yet fair for Liferay developers. Here’s how you can succeed:

This exam is based off of the Liferay Training course Back-End Developer.
Attend the Back-End Developer training course. Attending training is not required before you sit for the exam, but much of the exam material is based on concepts covered in training.
Review additional source material. Liferay Developer Network is an amazing complementary source of information for the exam.
Get hands-on development experience. Some of the topics covered on the exam require the kind of knowledge that comes from real experience developing for the Liferay Platform. If you have attended a developer training, be sure you've completed and reviewed all of the exercises presented during class, even the bonus exercises. If you haven't attended training, spend some time developing applications and customizations. It would also be helpful to review Liferay’s source code to ensure you're familiar with Liferay's best practices.
