On the i BT independent writing task, students write an essay in response to a prompt that can deal with a wide variety of general topics.
This task is based on the essay prompt only and does not include any reading passages or lecture excerpts.
Total section timing is 50 minutes, which is divided into a 20-minute segment for an integrated writing task and a 30-minute block for an independent writing task.
Human graders trained by ETS read all essays, which are assessed on a scale of 0 to 5 (on score reports, this is called a "task rating").
It is also crucial for students to practice writing essays within the i BT writing section's time constraints.
The most successful essays are coherently structured, articulately developed, and correct in terms of the conventions of written English.
TOEFL i BT writing standards can be set either at the institutional, divisional, or departmental level.
Some schools consider writing skills to be more important than others.
The quick answer to this is that an independent essay should be between 380 and 400 words, while an integrated essay should be between 280 and 300 words. It is true that when you are looking at the screen at the test center, the TOEFL software will suggest that a "typical" essay is much shorter than what I have suggested above.
I caution you that a "typical" essay should not be your target. If you want a higher score than that, you need to write more.
