The Role of a Lab Attendant in NVS Schools
A Lab Attendant in NVS is responsible for maintaining laboratories, handling scientific equipment, ensuring safety protocols, and helping teachers with experiments. It’s a non-teaching but highly technical role because you often deal with chemicals, instruments, and student experiments.
