In the context of the National Service Training Program (NSTP) in the Philippines, LTS stands for Literacy Training Service. It is one of the three components of the NSTP, along with the Reserve Officers Training Corps (ROTC) and the Civic Welfare Training Service (CWTS). The LTS is designed to train students to become teachers of literacy and numeracy skills to school children, out-of-school youth, and other segments of society. Graduates of the LTS become members of the National Service Reserve Corps, which may be tapped by the state for the delivery of literacy, civic welfare, and disaster risk reduction programs and activities.
