C2 SCHOOLS IN KENYA.
The **Cluster 2 (C2)** institutional tier under the Competency-Based Curriculum (CBC) framework primarily absorbs the high-performing **former Extra-County Schools** and select newly-elevated secondary centers. These regional powerhouses are structurally equipped to offer **Double-Pathway** tracks (STEM as a mandatory track alongside either Social Sciences or Arts & Sports Science).
Because Kenya features hundreds of C2 institutions across its 47 counties, providing a granular list of every small sub-county entry would result in a massive document.
