More than 45,000 elementary school teachers in Himachal Pradesh are trained every year by Samagra Shiksha. Because of the large number of teachers, the government follows a cascaded model of training, delivered manually by master trainers. However, due to sheer scale and size, this in-person training can only be delivered just once a year. Therefore, the government designed a programme, which can provide provide relevant, quality training to teachers on an ongoing basis. To this end, Samagra Shiksha created a Refresher Training programme, in collaboration with The TeacherApp, an online app-based training platform. Under this programme, Samagra Shiksha conducted a needs assessment survey of teachers which directly fed into the monthly training calendar of these 45,000+ teachers. Customized content is created every month by TheTeacherApp for teachers, without them having to travel for training sessions. Through the app a variety of content is being delivered to teachers every month, in the form of courses, teaching learning materials and the option of interacting directly with experts. At present, over 42,000 teachers have the app on their mobile, enabling them to upskill themselves and teach better.
