What TOEFL score do you need for Kaplan Business School?

KBS lists TOEFL iBT among the tests it approves. Proof of English from one of the listed tests must be completed within two years before the course starts.

For comparison, the same page sets IELTS Academic, including One Skill Retake, at 6.0 overall with 6.0 in speaking and writing and 5.5 in listening and reading for bachelor's and postgraduate programs.

Your offer and your visa are separate. Home Affairs says that for a TOEFL iBT result to be valid for Australian visa purposes you must select 'Taking TOEFL for Australia' when you register, and it lists TOEFL iBT Home Edition among the online tests it does not accept (Home Affairs English page).

Students who do not meet the undergraduate or postgraduate English criteria may be offered a pathway that includes an English for Academic Purposes course. KBS also accepts approved EAP courses from Kaplan or from ELICOS providers with a direct entry arrangement.

Requirements vary by programme and change between admissions cycles. The score that binds you is the one on your KBS programme page and in your offer letter, so check it there before you book a test.
