parts so that the developer has a large collection of isolated statements
such as ‘makes frequent errors with simple grammatical structures’ or
‘can give directions to places around town’. Groups of expert judges
fi rst decide whether these descriptions are meaningful in classifying
learners. If they are not, they are edited to make them more meaningful
or they are rejected. The experts then rank the statements according to

diffi culty. They may also classify them according to the aspect of
language being described. Statements of similar diffi culty are grouped
into sets to form a level and the level descriptions are arranged into a
scale. The resulting scales are taken to refl ect a consensus view of the
characteristics of different levels of language ability. This is, in outline,
the approach that was taken to building the scales associated with the
Common European Framework of Reference for Languages (CEFR)
(Council of Europe, 2001; North, 2000).

(2011, p. 9) objected to such quantitative ‘scaling
descriptors’ approaches, arguing that ‘Measurement-driven scales
suffer from descriptional inadequacy. They are not sensitive to the
communicative context or the interactional complexities of language
use.’ Both the ordering of descriptors into levels and the categories
used have been questioned because they seem inconsistent with second
language acquisition research (Green, 2012a). Areas of concern
include the trade-off discussed above between accuracy and range. As
learners expand their repertoire of language, or as they become more
fl uent, they often lose a degree of accuracy. As a result, learner language
does not necessarily or consistently become more accurate in the way
some scales seem to suggest. However, defenders of quantitative scales
point out that they are concerned with broad characterisations of
functional language ability, while second language acquisition research
tends to focus on discrete elements of language form (North, 2000).
Although learners become less accurate in their use of certain structures,
their overall ability to communicate may nonetheless improve.
It has also been argued that scales sometimes misrepresent the nature
of language in use. As noted in the overview of speaking abilities, highly
competent interactions between skilled speakers of a language are
rarely consistently ‘complex’ (CEFR, C2: grammatical accuracy scale)
with a ‘high degree of grammatical accuracy’ (CEFR, C1: grammatical
accuracy scale), displaying ‘a very broad lexical repertoire’ (CEFR, C2:
vocabulary range scale), but are often quite simple syntactically and
may involve a rather restricted range of vocabulary (Hughes, 2010).
