For the productive skills (Speaking and Writing) a measure of “inter-rater” reliability is given. This is
based on the examiner performance on a series of “control items” within the system, and indicates
how consistently the examiners are marking. Each examiner’s workload will comprise approximately
5% control items, i.e. responses taken from a pool of candidate performances that have been
scrutinised by senior examiners. All examiners are required to mark within tolerance of the agreed
mark, and if not, they are required to undertake further training.
The control items are regularly refreshed so that an examiner will not encounter the same control item
more than once. The inter-rater reliability is calculated based on the agreement of examiners on the
marks awarded for the control items. For the 2016–17 Annual Operating Report, a mean inter-rater
reliability value of .89 was recorded for Speaking and .85 for Writing for the Aptis General variant.
5. THE COMMON EUROPEAN
FRAMEWORK OF REFERENCE
FOR LANGUAGES (CEFR)
The CEFR is an ongoing project to provide a comprehensive framework for the description of
language proficiency at clearly defined levels. The CEFR was first published in 2001 with the goal to
provide “a common basis for the elaboration of language syllabuses, curriculum guidelines,
examinations, textbooks, etc. across Europe” (Council of Europe, 2001). It was quickly adopted not
only across Europe but in other regions of the globe as a transparent, accessible tool for educators
and policy makers. One of the key objectives of the CEFR is to facilitate “transparency in testing and
the comparability of certifications”

. As a part of this framework, there is a widely referenced set of
language proficiency descriptors, setting out basis of language proficiency across six levels:
A1 – A2 (Basic User)
B1 – B2 (Independent User)
C1 – C2 (Proficient User)
