Since 2019, the Teaching Learning Center of IUCAA has been organizing the school, adopting a teaching-learning model. In this model, we also invite college and university faculty members to mentor the student groups formed for the school's activities. This year, we invited five faculty members and 27 student participants out of 665 applicants. The lecture sessions started with a broad historical overview of radio astronomy and various radio observation techniques. The later lecture sessions covered radiative processes, the Sun, pulsars, fast radio bursts, interstellar medium, galaxies, black holes, and galaxy clusters, emphasizing the role of radio observations in revealing the nature of the systems. In the afternoon and early morning sessions, the participants worked in groups with their faculty mentors on experiments characterizing detector noise, gain, and directionality. They also used a horn antenna to observe the 21-cm Hydrogen emission to obtain Galaxy rotation curves. A highlight of the school was a day trip to the Giant Metrewave Radio Telescope, where the participants got a guided tour of the observatory's design and functioning by Subhashis Roy and Avinash Deshpande. On the final day, the student groups presented one of their chosen experiments and competed in a game-style quiz on the topics taught in the school. The
