TIP 4: HOW IS
THE IELTS TEST SCORED?
|
|
Many students ask about how their results
in various practice tests correlate to a possible score in the
actual IELTS test.
Others ask about how the IELTS test itself
is scored.
Both questions are complex. We have discussed
the importance of half Band scores in our IELTS 101 forum:
The quick answer
to the question about what practice test answers mean in terms
of a student's possible IELTS score is that it depends on the
difficulty of the practice test in question. A consistent score
of around 30 in many practice tests usually means around 6.5
– 7 but there is no way of being certain. Only the actual IELTS
test can tell you for sure.

School, Ramsgate, England.)
PRE-IELTS TESTS:
First, according to our
survey, around 92% of the students who have taken our Pre-IELTS
tests (in Basic Hints Lesson 1) seem to think they are useful
and/or give a reasonable indication of their present English
level. (See the conversion charts to pre-IELTS scores – which
are indicators only, and do not pretend to be probable IELTS
scores.)
THE ACTUAL IELTS TEST
SCORES:
We are told that the Band
Scores range from 0 to 9 for all four Sub-tests (listening,
reading, writing and speaking). We are also told that ALL the
Sub-tests (including Writing and Speaking from July 2007 onwards)
include the possibility of half Band Scores. So, it is now possible
to score, say, 5.5 or 6.5 etc. in all the Sub-tests.
It is well to remember
that the Writing and Speaking Sub-tests are subjectively
scored. That is, the score given is absolutely the opinion of
the examiner (and only one examiner too). Of course, these assessments
are made carefully, with reference to a detailed "list" of requirements
for a particular score. But they are, nonetheless, opinions
only.
The Listening and Reading
Sub-tests, however, are objectively scored. We are now
told (but only recently) that the 40 questions for each Listening
or Reading test carry equal weight. That is, one question does
not have more "marks" than another. So, one would expect that,
mathematically speaking, 20 questions out of 40 correct should
be...a band score of 9 divided by 40/20 = 4.5. However, this
is not actually the case.
Does a Band Score of 5
in the Listening and Reading Sub-tests mean a score that is
twice as good as a score of 2.5? Is a score of 4.5 only half
as good as a score of 9? It would seem logical, since the Listening
and Reading tests are objectively scored tests with 40 questions
each. But mathematical observations are not really so useful
here.
The first thing to mention
is that after the test you only receive the IELTS Band Score
you are given for a Sub-test and NOT the number of correct answers
achieved. And IELTS Band Scores are not always mathematically
derived. Some Listening or Reading Sub-tests might be deemed
(after careful trialling) to be more or less difficult than
others, and so the Band Scores are scientifically adjusted up
or down to account for this. Such adjustments have been calculated
and published for entire annual periods of time. For example,
according to the IELTS website, the mean raw score for candidates
given a Band Score of 6 for both Listening and Academic Reading
in 2004 was just 23 correct questions out of 40 (instead of
the expected 25).
So, 25 out of 40 questions
could indicate a Band Score of 6, or it could mean:
25/40
* 9 = 5.625 which is a score of
6.0 (after rounding up) PLUS an adjustment = 6.5
The facts are that candidates
are not told the number of correct questions achieved, nor how
these relate to a final Band Score. But this should not be looked
upon as a problem or cause for concern. The general trend is
to push scores UP not down.
PRACTICE TEST SCORES:
What can be said about
the scores achieved in practice tests published in books? Not
much.
Students do practice tests
from published materials in books and get a finite score out
of the number of questions in the practice test. They then,
quite naturally, ask their teacher how this score converts into
a Band Score. Answer? It doesn't.
Why? Because most of the
practice tests used in class have not been put through the official
IELTS testing process and the scores cannot be relied upon to
mean anything more than a possible display of skills.
The best we can say is
that when you consistently score around 30 questions out of
40 in a variety of practice tests (many of which are less difficult
than the actual test), and if this is supported by good speaking
and writing input, then you should be looking at a score of
around 6.5.
One last point to think
about: the IELTS test authorities now suggest that it takes
a minimum of 100 hours of intensive English study to improve
an overall score in IELTS by one Band Score. They used to suggest
that it took at least 3 months, by preventing anyone from taking
the test again before three months had passed*. Even if we use
the conservative figure of three months (which seems more likely
than just 100 hours), the implication is that, theoretically,
it would take the best totally non-English-speaking student
in the world:
3 * 9 = 27 months
... to become completely
fluent in every one of the four major English skills.
