Qt certification program has been alive since 2009, although we have not shouted out loud about it during the past few years. The exams have been updated to include Qt5 content, including Qt Quick and QML, so now it is possible to test your QML skills as well.
Why to get certified?
Join the group of 4,500 certified developers.
A certificate formalizes and proves you have practical Qt knowledge, when you are looking for new challenges. Yes, we mean practical knowledge. Although you do not have to write any C++ or QML code in the exams, there are plenty of code snippets, which you need to understand well to be able to answer to the exam questions.
With certified developers, companies can have a selling point when pitching their company’s credentials as an expert Qt shop.
Certificates and exams
Currently, we offer three kinds of certifications and corresponding certificates:
- Certified Qt and QML Developer
- Certified Qt C++ Specialist
- Certified Qt Quick Specialist
To become a certified developer, candidates must pass the Qt and QML Essentials exam. After additionally passing either of the specialist exams, candidates achieve the certified specialist status. We have developed the Widget UI and Application Engine exam for candidates, who want to test their widget and Qt C++ programming expertise. Candidates, preferring QML programming, can take the Qt Quick UI exam and become certified Qt Quick specialists.
Exams consist of multiple choice questions. In each exam, candidates have 60 minutes to reply the questions. The number of questions depends on the exam. The essential exam has 50 questions, from which 31 must be answered correctly. In the specialist exams, the passing score is 16, while the total number of questions is 30. A question example is given below:
Select all statements, which are true in terms of QString
- QString extends QObject.
- It is an implicitly shared value type.
- QString stores the data in the compressed binary format, so it is more memory efficient than QByteArray.
- QString stores a string as Unicode characters.
We do not expect you remember all the Qt classes and QML types by heart. However, you should know some essential classes, like QObject, QString, QWidget, QQuickItem very well. In addition, make sure to understand the essential Qt programming concepts, such as Qt object memory management, meta-object system, widget layout management or QML bindings and signal handlers.
