This article describes the development and calibration of items from the 1997 to 2006 Tertiary Entrance Exams (TEE) in Chemistry conducted by the Curriculum Council of Western Australia for the purposes of establishing a Chemistry item bank. Only items that met the strict Rasch measurement criterion of ordered thresholds were included. Item Residuals and Chi-square conformity of the items were likewise scrutinized. Further, specialist experts in chemistry were employed to ascertain the qualitative properties of the items, particularly the item wording, so as to provide accurate item descriptors. An item bank of 174 items was created. This item bank may now be accurately used by teachers in their classrooms for the purposes of developing class assessments in Chemistry and/or for classroom diagnostic purposes.
本文描述了西澳大利亚课程委员会为建立化学题库而对1997年至2006年高等教育入学考试（TEE）化学科目中的题目进行的开发与校准。仅纳入了符合有序阈值这一严格拉施测量标准的题目。同样对题目的项目残差和卡方拟合度进行了审查。此外，还聘请了化学领域的专家来确定题目的定性属性，尤其是题目措辞，以便提供准确的题目描述。创建了一个包含174道题目的题库。现在，教师可以在课堂上准确使用这个题库，用于开展化学课堂评估和/或课堂诊断。
