多益測驗的準確性

多益測驗的準確性

多益測驗結果的正確性如何？

多益測驗提供一個相當可信的語言能力測驗指標。根據廣泛大量的研究結果顯示，多益測驗分數和其他英語能力檢測的分數有相當強的關聯，這就表示多益測驗結果是個有效的英語能力檢測數據。如您需要更多關於多益測驗的信度及效度相關資料，可參考多益測驗技術手冊。

信度 指的是一個測驗分數的一致性、可信賴度或者是穩定程度。
效度 指的是確保每一次測驗所量度的是測驗設定要量度的範圍。

雖然多益測驗具有相當的可信度，但沒有任何一個測驗是完全百分之百的正確和一致。如果一個人在短時間內參加數次考試，那麼得到的平均值會是真實正確的分數。

How accurate are TOEIC test results?

The TOEIC test provides an extremely reliable indication of English proficiency.

Extensive research has demonstrated that TOEIC test scores are strongly related to scores on many other measures of English language proficiency. This indicates that the TOEIC test is a valid measure of English language proficiency. For more information on the reliability and validity of the TOEIC test, please see the TOEIC Technical Manual.

Reliability is an indication of the degree of dependability, consistency, or stability of scores on a test.
Validity refers to the extent to which a test measures what it is supposed to measure.

Although the TOEIC test is highly reliable, no test measures performance with perfect accuracy and consistency. An individual who takes several, versions, or forms, of the test within a short period of time obtains a number of scores that center around an average value known as the “true” score. Two-thirds of the time, the obtained score on either the Listening Comprehension or Reading Comprehension section of TOEIC test is within 25 points of the true score.
