雅思考试评分是怎样完成的？

据《IELTS评分标准、分数报告和解释》,所有雅思评分都由评卷官和考官在考试中心完成。所有评卷官必须事先接受培训,以其理解评分规定,并且证明其能够根据评分标准进行评分。评卷官每两年要重新接受测试,以其评分符合标准。每次考试都有系统监测,并对部分答卷进行二次评分。

Score processing, reporting and interpretation.
 
All IELTS marking takes place at the test centre by trained markers and examiners. Markers are trained to understand theIELTS marking policy and are required to demonstrate that they are marking to standard before they are allowed to mark Litening and Reading papers. Markers are retested every two years to ensure that their marking remains up to standard. Systematic monitoring and double marking of a proportion of answer sheets is carried out at each administration.
 
Examiners for the Writing and Speaking sub-tests are recruited and trained in line with agreed standards. They are required to demonstrate that they are marking to standard every two years in addition to on-going monitoring of their performance.
 
Candidates receive scores on a band Scale from 1 to 9. A profile score is reported for each skill. The four individual module scores are averaged and rounded to produce an Overall Band Score, Overall Band Scores and scores for each sub-test( Listening,Reading，writing and Speaking)are reorted in whole bands or half bands.
 
Overall Band Score
 
Candidates receive a Test Report Form setting out their Overall Band Score and their scores on each of the four sub-tests Listening, Reading, Writing and Speaking Each ofequally weighted. The Overall band Score is calculated by taking the mean of the total of the four individual sub-test scores .
 
Overall Band Scores are reported to the nearest whole or half band. for the avoid ance of doubt, the following rounding convention applies; if the average across the four skills ends in 25, it is rounded up to the next half band. and if it ends in 75. it is rounded up to the next whole band.
 
Thus a candidate achieving 6.5 for Listening, 6.5 for Reading, 5.0 for Writing and 7.0 for Speaking would be awarded an Overall Band Score of 6.5.
 
Likewise a candidate achieving 4.0 for Listening, 3.5 for Reading, 4.0 for Writing and 4.0 for Speaking would be awarded an Overall Band Score of 4.0.
 
Listening and Reading
 
IELTS Listening and Reading papers contain 40 items and each correct item is awarded one mark the maximum raw score a candidate can achieve on a paper is 40.Band scores ranging from Band 1 to Band 9 are awarded to candidates on the basis of their raw scores.
 
Although all IEltS test materials are pretested and trialled before being released as live tests, there are inevitably minor differences in the difficulty level across testsIn order to equate different test versions, the band score boundaries are set so that all candidates results relate to the same scale of achievement. This means, for example, that the Band 6 boundary may be set at a slightly different raw score across versions.
 
The tables below indicate the mean raw scores achieved by candidates at various levels in each of the Listening, Academic Reading and General Training Reading tests and provide an indication of the number of marks required to achieve a particular band score.
 
The Academic and General training papers are graded to the same scale. The distinction between the two modules is one type. Academic papernay contain texts featuring more difficult vocabulary or greater complexity of style. It is usual that, to secure a given bandscore, a greater number of questions must be answered correctly on a General Training Reading paper.
 
Writing and Speaking
 
When marking the Writing and Speaking sub-tests, examiners use detailed performance descriptors which descr written and spoken performance at each of the 9 IELTS bandWritingExaminers award a band score for each of four criterion areas: Task Achieve ment( for Task 1 ), Task Response(for Task 2), Coherence and Cohesion, Lexical Resource and grammatical Range and accuracy. The four criteria are equally weighted.
 
Speaking
 
Examiners award a band score for each of four criterion areas: fluency and Coherence. Lexical Resource. grammatical Range and Accuracy and Pronunciation The four criteria are equally weighted.
