摘　　要：实时线性考试(Linear On-the-Fly Test,LOFT)是一种在计算机上实施的,以题库形式为发送基础的考试设计:根据事先设定好的规则,整套试卷在考生开考时随即从题库中产生,试卷之间题目或多或少总有不同。本文比较LOFT和固定试卷以及计算机自适应考试(CAT)设计之间的差别,并通过一个虚拟案例介绍考试主办方在实施这种设计时需要考虑的具体环节。Linear On-the-Fly Testing （LOFT） is a pool-based test design in which tests are delivered on a computer. Based on pre-determined rules, a LOFT form is constructed immediately before a candidate starts the exam, and each candidate receives a somewhat different test form. This paper conceptually compares LOFT with two other test designs： linear fixed-form and computerized adaptive testing （CAT）. Similarities and differences across different test designs are summarized. This paper also demonstrates how to design and implement a LOFT design for a testing program.
