Three Exams, Similar but Distinct Uses
To prove your French level for an administrative procedure, three exams are routinely accepted: DELF (Diplôme d'études en langue française), TCF IRN (Test de connaissance du français — Integration, Residence, Nationality) and TEF IRN (Test d'évaluation de français — same scope). Their goals overlap but they differ in format, validity period and scoring logic. The right choice depends on the document you need and on your profile.
DELF: An Official, Lifetime Diploma
DELF is issued by the French Ministry of Education through France Éducation international. Each diploma matches a specific level (A1, A2, B1, B2, C1, C2) and is valid for life. It is a strong asset if you plan several procedures over time or want a document recognized by universities and employers. The trade-off: you must register for a fixed session, the exam is longer and the preparation more demanding.
TCF IRN and TEF IRN: Four-Skill Tests, Valid Two Years
TCF IRN (France Éducation international) and TEF IRN (CCI Paris Île-de-France) were designed specifically for integration, residence and nationality procedures. They assess all four skills (listening, reading, speaking, writing). Results are delivered quickly but stay valid for only two years. This is the most pragmatic option when an imminent procedure is at stake and the timeline is tight.
How to Choose: Three Questions to Ask
First, what is the deadline? If the prefecture wants a certificate within weeks, a TCF IRN or TEF IRN will do. Second, do you expect more procedures later (renewal, nationality, professional mobility)? If so, a lifetime DELF may be the better investment. Third, where are the open centers near you? Geographic availability often tips the scale toward one test over another.
