DALF stands for Diplôme approfondi de langue française (Advanced diploma in French language).
The DALF certificate is useful to anyone wanting to pursue higher education studies in France or in French, as it certifies you have the required language skills and you won’t need to take a separate language test.
If you’re planning on applying to study a master’s degree at a university in France, you have to pass DALF C1.
DALF is also often the diploma of choice for anyone wanting to get a job in large companies where employees are expected to be fluent in French.
