Avanti Fellows designed Project Sankalp, a low-cost blended learning innovation that combines a structured curriculum, peer learning, teacher support, and video instruction. With support from Development Innovation Ventures and in partnership with the Government of Haryana, J-PAL, and the Michael and Susan Dell Foundation, Avanti Fellows is conducting a randomized controlled trial (RCT) to test the effectiveness of two versions of the program in public schools (with and without information and communication technology) against a control group using traditional classroom curriculums. Early studies show that Sankalp improves outcomes at a lower cost than comparable top education interventions for greater cost-effectiveness. Over three years, Avanti Fellows will expand to 240 schools with 36,000 students enrolled in grades 9 and 10. If results are sustained, there will be a strong case for increased interest and scaling support from several Indian state governments.
