本文的主要目的在探討並設計一套能符合臺灣地區大專院校的「線上適性聽力分級測驗」。此「線上適性聽力分級測驗」是「網路適性化英語分級測驗平台」的第二部份。目前正在研發的「網路適性化英語分級測驗平台」，初期是希望能幫助本校大一新生入學時，在第一週上課時就能依照學生的英語能力分配到適合他們程度的英語課程。在電腦適性化語言測驗(computer-adaptive language test)中，每一位考生所考的題目並不完全一樣，下一道題目的出現，是根據這一道題目答對與否而有所變化。如果這一題答對，下一道題目將會比較困難；相反的，如果這一道題目答錯，下一道題目將會比較簡單。電腦適性化語言測驗一般被認爲比較快速可以測出學生能力、比較可靠、比較節省成本。大部份電腦化測驗(computer-based test)是由電腦伺服器用亂數挑選的方式從題庫中挑選題目給考生，考生考試的題目出現順序雖然不一樣，但是所有考生都考相同的題目。此次「線上適性聽力分級測驗」是希望設計出一套電腦在題庫中選題時能遵照較嚴謹的規範，用比較科學的方式，挑選出接近學生程度的題目。本文也會針對「線上適性聽力分級測驗」上的題型做一分析整理。聽力題庫腳本中的英語用字難易度、題目編碼所代表的意義、以及出題介面等相關問題也會有所介紹。

A prototype of an online adaptive placement test of listening comprehension has been established. This test system, which is the second stage of a web-based adaptive English placement test platform, is now being developed to help universities group freshman students into classes which match their English proficiency. In a computer-adaptive language test (CALT), each examinee takes a unique test that is tailored to his ability level. It is generally believed that CALT is faster, more reliable and more cost-effective. While most computer-based test models use computer servers to randomly choose next suitable test items, more carefully designed regulations are applied to the item selection from the test bank so that a listening comprehension test will be more efficient and reliable. Different types of listening test will also be introduced. Finally, Some practical issues such as the classification of the word list, definitions of item codes, and design of test makers' interface are also discussed.
