<p>This article examines officials’ views and perceptions regarding the effectiveness of Right to Information Act’s in fostering accountable, transparent, and effective public institutions in Bangladesh, with a specific focus on its alignment with Sustainable Development Goal 16.6. Drawing on a survey of 202 government officials familiar with the Act, supported by explanatory case insights, the study applies quantitative analyses which include frequency distribution, correlation, principal component analysis, and multiple regression to assess officials’ perceptions. Based on the viewpoints of the respondents, the data revealed that the Right to Information Act, 2009 is highly effective in establishing effective, accountable, and transparent institutions, which is admitted by 65.3% of the sample population, though 1.5% of respondents deny it. PCA identified five principal components (eigenvalues &gt; 1) explaining 73.545% of variance. Pearson correlation showed three independent variables significantly related to the dependent variable, with officers’ changing attitudes having the strongest correlation (<i>r</i> = 0.813, <i>p</i> &lt; 0.01). Regression analysis confirmed strong predictive relationships, while case studies reinforced these survey results. However, the results also reveal critical challenges, such as inadequate awareness among officials, less training, and structural implementation gaps constrain its broader impact. By explicitly acknowledging these weaknesses and integrating them with existing literature, the study demonstrates that the RTI Act’s potential to strengthen governance is contingent on institutional support and capacity-building initiatives. Through a quantitative-dominant explanatory sequential design, it not only measures informed officials’ perceptions but also contextualizes them within systemic barriers, offering a balanced understanding of the Act’s promise and limitations.</p>
