Foundation of quality examination is based on the key features of validity and reliability of question papers. Question papers of examination boards in Pakistan—usually these features as contents of a question paper—are written by a single paper setter. To address these issues, Federal Board of Intermediate and Secondary Education (FBISE) recruited and trained senior faculty members to write, review, and moderate multiple-choice question (MCQ) items which are the key components of its question papers. Fitness of these items was determined through field testing and analysis using standard measuring indices. Aggregate item survival rate has been 43% despite relaxed limits of difficulty index (DIFI) and discrimination index (DI). However, the questions with extraordinarily low or high DIFI values were found to be associated with other problems as well. Moreover, apart from utility of point biserial (pbs), mutual relationship of distractor efficiency (DE) and DIFI is also discussed. And based on these attributes, these questions were declared fit or unfit for future use or review respectively.

题项的评价、分类和优化

质量考试的基础是试卷的效度和信度这两个关键特征。巴基斯坦考试委员会的试卷——通常将这些特征作为试卷的内容——由一个单独的试卷员编写。为解决这些问题，联邦中级和中等教育委员会 (FBISE) 招募并培训了资深教员撰写、审查和审核多项选择题 (MCQ)，这是其试卷的关键组成部分。这些项目的适合度是通过使用标准测量指数的现场测试和分析来确定的。尽管放宽了难度指数 (DIFI) 和辨别指数 (DI) 的限制，但总体项目存活率仍为 43%。然而，发现 DIFI 值特别低或特别高的问题也与其他问题有关。此外，除了点双列 (pbs) 的效用外，还讨论了干扰效率 (DE) 和 DIFI 的相互关系。并且基于这些属性，这些问题分别被宣布为适合或不适合将来使用或审查。
