+  <h2>The Bertelsmann Transformation Index</h2>
+  <h3>What it is</h3>
+  <p>
+    The Transformation Index BTI is a comparative assessment of political and economic transformation and the quality of governance in 137 developing and transition countries. BTI publishes two composite rankings: the <strong>Status Index</strong> and the <strong>Governance Index</strong>. Scores are based on standardized expert assessments using a 10 to 1 scale anchored by descriptive benchmarks.
+  </p>
+  <h3>History and purpose</h3>
+  <ul>
+    <li><strong>Origins and cadence</strong> The BTI has been produced by Bertelsmann Stiftung since 2003 and appears biennially.</li>
+    <li><strong>Scope</strong> Focuses on transformation contexts by excluding long consolidated OECD democracies.</li>
+    <li><strong>Purpose</strong> Provide transparent, comparable evidence to guide policy, research, and practice toward democracy under the rule of law and a socially responsible market economy.</li>
+  </ul>
+  <h3>How the methodology works</h3>
+  <ul>
+    <li><strong>Framework</strong> 17 criteria and 49 indicators organized into Democracy, Market Economy, and Governance.</li>
+    <li><strong>Expert process</strong> One country author drafts a report and ratings. A second expert independently reviews. Scores undergo regional and interregional calibration and final board review to ensure cross country comparability.</li>
+    <li><strong>Scale</strong> Indicators are rated 10 to 1 with anchored descriptors so that like conditions receive like scores across countries and time.</li>
+    <li><strong>Indices</strong>
+      <ul>
+        <li><strong>Status Index</strong> Average of political transformation and economic transformation.</li>
+        <li><strong>Governance Index</strong> Average of governance criteria, interpreted in light of the Level of Difficulty.</li>
+        <li><strong>Level of Difficulty</strong> Captures structural constraints that shape feasible governance performance.</li>
+      </ul>
+    </li>
