Cambridge English: Key, also known as the Key English Test (KET), is an English language examination provided by Cambridge English Language Assessment (previously known as University of Cambridge ESOL examination). Cambridge English: Key is a basic level qualification which demonstrates the ability to communicate using English in simple situations.
Launched in 1994, Cambridge English: Key is designed to be the first step for students wishing to progress towards higher level English language qualifications, and aims to support learners to master the basics in English. It is focused on Level A2 of the Common European Framework of Reference for Languages (CEFR).
Cambridge English: Key is offered in two variations: Cambridge English: Key (KET), for adult learners, and Cambridge English: Key (KET) for Schools, for school-aged learners. Both versions of the exam lead to the same qualification, the Key English Test. Both versions have the same exam format (three exam papers) – the only difference is that the topics in the ‘for Schools’ version have been targeted at the interests and experiences of school-aged learners.
Cambridge English: Key (KET) for Schools is part of a suite of qualifications designed specifically for school-aged learners, which includes Cambridge English: Preliminary (PET) for Schools, focused on CEFR Level B1, and Cambridge English: First (FCE) for Schools, focused on CEFR Level B2.
Cambridge English: Key was developed; through extensive trialling, as the Key English Test between 1991 and 1994. It was launched to offer students a basic qualification in English and provide a first step for those wishing to progress towards higher levels, such as Cambridge English: Preliminary (PET).
In 1999, Cambridge English: Key was reviewed with stakeholders and an updated version of Cambridge English: Key was launched in March 2004. Cambridge English: Key is focused on Level A2 of the Common European Framework of Reference for Languages (CEFR), although it also certifies Levels B1 and A1.
From 2009, in response to increased use of Cambridge English exams within schools, Cambridge English Language Assessment introduced versions of some of its exams designed for school-age students. This included: Cambridge English: Key (KET) for Schools, Cambridge English: Preliminary (PET) for Schools and Cambridge English: First (FCE) for Schools.
