This study presents the expert review and face validation of a survey instrument specifically designed to assess Halal Business Responsibility Practices (HBRP) among industry practitioners and academic experts in Halal-related fields. Given the increasing significance of integrity, sustainability, and strategic compliance in Halal food business practices, it is crucial to establish the content validity of the instrument before distributing the survey on a larger scale. The validation process was conducted in two stages. First, face validity is performed with small group of target respondents to check clarity, wording, layout, and readability of the instrument items. In the second stage, the instrument was distributed to Halal industry experts and academicians to evaluate the relevance and clarity of the survey items. This evaluation utilized the Item-Level Content Validity Index (I-CVI) and the Scale-Level Content Validity Index (S-CVI/Ave), aiming for acceptable indices (I-CVI ≥ 0.78; S-CVI/Ave ≥ 0.80). The findings also show a high Item-Level Content Validity Index (I-CVI = 0.98) and Content Validity Ratio (CVR = 0.96), indicating excellent expert agreement on item relevance and essentiality Further discussion is provided to ensure the relevancy and appropriateness of the research instrument are in place, as the reliable assessment tool for measuring the Halal Business Responsibility practices in the Halal food industry context.
