You are currently viewing How Is a TOEFL® iBT Test Scored and How Does This Score Compare to Other English Tests?

The maximum score on each section of the test is 30 points. The maximum score for the test is 120 points.
Scores are valid for 2 years. If a person takes the test more than one time, then the person can keep the highest score on each section (My Best Score). For example, if on the first test, the person gets 21 points on the reading section, but on the second test, the person gets 18 points on the reading section, then the person can keep the 21 points on the reading section and use it as part of his or her official score.

1. Reading Section

On the reading section, scores are determined based on the number of correct answer choices to questions. The number of correct answers is used to create a “raw score”. This score is higher than 30 points, and it is based on the number of points that are possible from the questions in the section. It is possible for a question to have a value of more than 1 point. The “raw score” is then turned into a “scaled score”. This score depends on the difficulty of the section and is adjusted by ETS on a test-by-test basis. The “scaled score” is the official score that a person gets for the reading section. Here is a sample of a scoring chart:


*Raw Score: Scaled Score

3. Speaking Section

On the speaking section, responses are sent to ETS for evaluation. Scores are based on human evaluators and an AI evaluation program.
There are 4 exercises, and each of them is scored from 0 to 4 points by a human evaluator and the AI evaluation program. These scores are whole numbers. From these 8 scores, an average is calculated, and this average is multiplied by a conversion rate of 7.5 to determine a person’s score on the speaking section. Here is a sample of student score:

Speaking 1: Human Evaluator [3] / AI Evaluator [3]
Speaking 2: Human Evaluator [2] / AI Evaluator [3]
Speaking 3: Human Evaluator [3] / AI Evaluator [2]
Speaking 4: Human Evaluator [3] / AI Evaluator [2]
Average Score: 2.625
Average Score x Conversion Rate = 19.675 -> 20 points

Scores are determined by various measures. Here is a general description:

DELIVERY

A person who speaks well is easy to understand, does not pause much while speaking, speaks at a natural speed and rhythm, has good pronunciation, and has appropriate intonation based on the specific intonation.

Writing 1: Human Evaluator [3] / AI Evaluator [4]
Writing 2: Human Evaluator [3] / AI Evaluator [2]
Average Score: 3
