France is a growing destination for Indian students, and its language certificates confuse people in a way that costs time and money.
DELF and DALF are diplomas from the French Ministry of Education, awarded at a fixed CEFR level and valid for life. DELF covers A1 to B2; DALF covers C1 and C2. You choose the level before you sit it, and you either reach that level or you do not.
TCF is a test, not a diploma. You sit one exam and it places you on a level from A1 to C2 by how you perform — and the result is valid for two years. Some universities and the visa and residency routes specify TCF particularly, often the TCF-DAP version for first-year undergraduate admission.
Which to take. Read the programme page for the exact certificate name and level. If a programme accepts either, DELF/DALF is usually the better investment because it never expires — unless the application specifically names TCF or TCF-DAP, in which case the diploma will not be accepted in its place.
Typical levels. Around B2 for most French-taught bachelor's and master's programmes; B1 is sometimes enough for a pathway or foundation year; C1 for demanding programmes and for anything clinical. English-taught programmes in France may require no French for admission at all — but A2/B1 is commonly needed later for residence purposes, and for living there at all.
