The Central Board of Secondary Education launched the Sahodaya Movement mainly to introduce and experiment several nation-wide programmes, projects and activities for educational renewal and improvement. The Board is of the view that the active participation of schools in the true Sahodaya "spirit of living together" is a great source of trust, confidence and strength to CBSE as a National Board. The total number of Sahodayas has swelled to more than 260. Sahodaya Clusters form an important link between CBSE and its affiliated schools and it is a growing necessity today to be a part of it.
