The problematic, "which diploma do learners and teachers choose and under which criteria and conditions? What are the advantages and disadvantages of the Sorbonne B2 and DELF B2 diplomas? The aim has been to study and compare the two diplomas, DELF B2 and Sorbonne B2, to help teachers and learners to choose the diploma that suits them and their needs, and to see if there is a need to improve them. More specifically, they will be presented to show their strengths and weaknesses, their similarities and differences. To carry out our investigation, we used objective tools, such as questionnaires distributed to the learners and an interview guide which we used to interview Mr. Nicolas Christodoulou, Head of the Examination Department of the I.F.G., Doctor of Letters of the University of Paris-Sorbonne. The result of this research led to certain proposals, on the one hand, for the improvement of the two diplomas, and on the other hand, for the better preparation of the students who take the examinations.
