# Score processing, reporting and interpretation

　　All IELTS marking takes place at the test centre by trained markers and examiners. Markers are trained to understand the IELTS marking policy and are required to demonstrate that they are marking to standard before they are allowed to mark Listening and Reading papers. Markers are re-tested 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 modules 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 score is reported for each skill module of the test. The four individual module scores are averaged and rounded to produce an Overall Band Score. Overall Band Scores and Listening and Reading scores are presented as whole or half bands; Writing and Speaking band scores are reported in whole bands only.

　　## Overall Band Score
　　Candidates receive a Test Report Form setting out their Overall Band Score and their scores on each of the four modules, Listening, Reading, Writing and Speaking. Each of the module scores is equally weighted. The Overall Band Score is calculated by taking the mean of the total of the four individual module scores.
　　Overall Band Scores are reported to the nearest whole or half ba12 For the avoidance 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 ba12
　　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 (25 ÷ 4 = 6.25 = Band 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 (15.5 ÷ 4 = 3.875 = Band 4.0).
　　On the other hand, a candidate achieving 6.5 for Listening, 6.0 for Reading, 6.0 for Writing and 6.0 for Speaking would be awarded band 6 (24.5 ÷ 4 = 6.125 = Band 6).

　　## 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 tests. In 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. Click here for a detailed description of the IELTS Question Paper Production process.
　　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 modules during 2004 and they 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 of genre or discourse type. Academic papers may contain source texts featuring more difficult vocabulary or greater complexity of style. It is usual that, to secure a given band score, a greater number of questions must be answered correctly on a General Training Reading paper.

　　## Writing and Speaking
　　When marking the Writing and Speaking modules examiners use detailed performance descriptors which describe written and spoken performance at each of the 9 IELTS bands.
　　Writing 　　Examiners award a band score for each of four criterion areas: Task Achievement (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.


HK的补充：评分标准的问题大家记住一个大概就可以了，平时按照最bt的标准算分，给自己以鼓励

到了真正考试的时候，这个标准官方会根据实际考试的难度微调，所以精确的21 22 23这种数字没有多少意义

o.5 就是 整数之间的个数
