French Faster offers online preparation for the TCF-ANF Test, one of the French language proficiency tests that candidates applying for French citizenship can do to prove knowledge of the French language. Other acceptable tests would include TEF or TEFAQ, TFI, DELF B1, DCL FLE and BULATS.
The minimum level requirement by the French Interior Ministry is the B1 level as defined by the Common European Framework of Reference for languages. The B1 level is the level at which pupils should be at the end of the compulsory education cycle. It implies being able to “listen”, “take part in a conversation” and “orally express oneself continuously”.
