An Evaluation of the Consistency between Learning Objectives and Teachers' Tests Using the Index of Item-Objective Congruence (IOC) by Expert Assessment during the Academic Years 2022-2024

Abstract

This study, titled “An Evaluation of the Consistency between Learning Objectives and Teachers’ Tests Using the Index of Item–Objective Congruence (IOC) by Expert Assessment during the Academic Years 2022–2024” aims to: (1) evaluate the effectiveness of test item– objective alignment assessed through the IOC method; (2) analyze the congruence levels of items reviewed by experts during the academic years 2022–2024; and (3) provide recommendations for improving test item development to ensure alignment with curriculum objectives and assessment standards. The research was conducted within the context of the 2023 revised General Education curriculum at Suan Sunandha Rajabhat University, which emphasizes 21st-century learner competencies and employs a large-scale, online examination system requiring systematically validated test items. A quantitative research methodology was used, drawing on IOC assessment data from experts who evaluated general education test items between 2022 and 2024. Statistical analyses were conducted to determine the degree of alignment between learning objectives and test items, supplemented by qualitative recommendations for test quality improvement. The findings highlight gaps in previous evaluation practices, particularly the absence of systematic studies on the effectiveness of IOC scores and overall item quality trends. The results of this study provide essential insights and constructive feedback for instructors and test developers, contributing to the ongoing enhancement of assessment quality and alignment within the General Education Program.
