SSS is designed to maximise gains and give sustained benefits to students. So the system of SSS trainings includes repetation of the trainings ideally every 6 months, but at least once every year for every class. Such refresher courses are expected to be run by school teachers trained in the course of the initial SSS trainings by trainers of IAP and/or its training partners, while IAP will continue lending off-site support and quality control to the schools.
