The number people want is "six months". The number that gets quoted is "600 hours". Both are useless on their own, because the same 600 hours spread over five years produces a different speaker than 600 hours over eighteen months.
So here is the timeline we actually see, again and again, with students who take two private lessons a week and do twenty minutes of something on most other days.
A1, the first six to ten weeks
You can greet, introduce yourself, order, ask what things cost, say where you are from and what you do. You understand a patient Italian speaking slowly about a predictable subject. This is the stage that feels fastest, because everything is new and everything sticks.
A2, month three to month six
The past tense arrives, and with it the ability to tell someone what you did yesterday, which is most of what conversation is. You can handle the whole surface of a trip: hotels, trains, restaurants, pharmacies, small talk with a shopkeeper. Most people going to Italy for two weeks would be delighted to be here.
B1, month nine to month eighteen
The independent level, and the one the Italian state asks for in a citizenship application. You can explain a plan, give reasons for an opinion, follow the main points of a normal conversation between two Italians, and get through an unexpected problem in Italian without switching to English.
B1 is not sophisticated Italian. It is Italian you no longer need help with. That is why it is the level that matters.
B2 and beyond, year two to year four
Films without subtitles, newspapers without a dictionary, arguments at dinner where you hold your own. This is where the curve flattens: the jump from nothing to A2 takes a few months, the jump from B1 to B2 takes about as long again, and the jump from B2 to C1 can take years, because each step buys you less visible progress than the last.
The three things that actually change the answer
- Frequency, not volume. Twenty minutes daily beats three hours on Sunday, every time. Language lives in retrieval, and retrieval needs to happen often.
- Speaking hours specifically. Reading and listening build comprehension; only talking builds fluency. Students who stall have almost always stopped talking, not stopped studying.
- Whether you have a reason. A trip in April, cousins in Calabria, a passport application. Students with a concrete deadline move roughly twice as fast as students learning "one day".
What we tell people on the first call
If you have a trip in two months, we will not promise B1. We will get you functional for that trip, which is a real and achievable goal. If you need certified B1 from zero, plan for nine to eighteen months and we will build a dated schedule backwards from an exam session. Anyone promising fluency in eight weeks is selling you something.
