How the TOEIC is scored

You answer 200 questions and receive a number between 10 and 990. What happens in between is described badly on most sites, because they assume a simple proportion. It is not one, and the difference has practical consequences.

Starting point: there is no penalty

The ETS score user guide puts it without ambiguity: scores are determined by the number of questions answered correctly, and there is no penalty for wrong answers.

From raw answers to a scaled score

The number of correct answers in each section is converted onto a scale of 5 to 495. The total is the sum of the two section scores, giving a minimum of 10 and a maximum of 990.

That conversion is not fixed. It is re-derived for every test form, and its purpose is stated explicitly in the ETS documentation: to ensure that scores obtained on different administration dates mean the same thing in terms of English proficiency. If one session had a slightly harder Part 7, the conversion absorbs it.

How precise is your score, really?

This is the part nobody reads and that changes everything. ETS publishes the standard error of measurement for the test: about 25 scaled points per section.

The example given in the official guide runs like this: if you score 300 on Listening, then two-thirds of the time your "true" score lies between 275 and 325. The number printed is not an exact measurement — it is the centre of a range.

Practical application: a candidate on 780 and a candidate on 800 are not reliably distinguishable. If your school demands 785 and you get 770, that is not an English problem, it is a margin problem — and the only remedy is to aim far enough above the threshold that measurement noise does not decide for you.

What is on the score report

Beyond the score itself, the official report carries three things people routinely overlook:

• A percentile rank — the share of public-programme test takers over the past three years who scored below you. ETS refreshes that table every May.
• Proficiency descriptors — three possible statements for Listening, four for Reading — describing what someone at your level can typically do. For space reasons, only statements of strength are printed.
• Percentage correct by ability measured, which is genuinely useful for aiming revision.

Having a score reviewed

If you believe your result misrepresents you, a review can be requested within three months of the test date. The answer sheet is rescored and a second report issued. If a discrepancy is found, ETS bears the cost of rescoring; if none is found, a fee may be charged.

Note that the procedure checks the marking, not the perceived difficulty of the session. It rarely changes anything, precisely because scoring is automated.
