What a TOEFL^® Band 4 Actually Means

Band 4 and band 4.5 are both B2

Since January 2026 the test reports on a 1–6 scale in half bands, and that scale maps onto the Common European Framework. Bands 4 and 4.5 are both B2. Band 5 is where C1 begins.

The mapping is the same for every section and for the total. A 4 in Reading and a 4 in Speaking describe the same level of ability in those two skills — which was not true of the scale the test used before.

What B2 gets you

B2 is the level where the language holds together. You can follow a lecture on a subject you know something about, separate the argument from the aside, and tell an opinion from a fact. You can read a long text and come away with the shape of it. You can state a position and support it, and be understood without anyone straining.

The sentences are structurally sound. Tenses land where they should. Relative clauses attach in the right place. Articles are mostly right. That is not a small achievement, and most of the work of getting there is already behind you.

Where it stops

B2 comes apart in three predictable places, and they are the same three for almost everyone.

Unfamiliar territory. Take away the familiar subject or the clear signposting and comprehension drops faster than it should. The words are known; the effort of assembling them leaves nothing spare for inference.

Time pressure. Grammar that is reliable in writing becomes hesitant when spoken to a clock. The pauses come while a structure is being planned, not while an idea is.

Precision. A B2 speaker can say a thing is true. Saying it is probably true, or true in one respect and not another, or true in a way you want to concede before disagreeing — that control is what C1 adds, and its absence is the most common reason a strong-sounding answer scores a 4 rather than a 5.

The part almost nobody explains: a 4 is an average

The total is now the average of the four section scores, not a sum. That sounds like a technicality and it is not, because two students with the same band 4 can be nothing alike.

A student at 4 / 4 / 4 / 4 is evenly B2 across the board. A student at 5 / 5 / 3 / 3 also averages 4 — but is C1 in the skills they read and listen with, and B1 in the two they produce with. Those two people need completely different practice, and the total score cannot tell them apart.

So the number to look at is not the average. It is the lowest section. Averaging rewards being good at reading and listening, which are the easier sections to move, and quietly hides a speaking or writing score that is holding everything down. Some programs also set a separate minimum on individual sections, which a comfortable average will not satisfy.

What moves a 4 to a 5

Not more vocabulary, and not longer sentences. The distance from B2 to C1 is not a matter of knowing more — it is a change in what you are doing with what you already know.

B2 is structural: the sentence has to come out correct. C1 is expressive: the structure is already reliable, and the work moves to precision. Saying how certain you are. Conceding a point before arguing against it. Choosing a reporting verb that carries the right shade. Using the passive to move attention rather than out of habit.

Which is why more practice at the same level does not move the score. A student stuck at 4 is usually not making more errors than a student at 5 — they are making the same small number of errors while attempting less. The way out is to attempt the more precise thing and get it wrong for a while.

If you are aiming higher

Competitive programs generally look for C1, which means a 5. Getting there means finding your lowest section rather than your average, and working on the thing that section actually tests — which for most people is speaking, and for most people is also the section they practice least, because it is the uncomfortable one.
