This Trainer’s Reference Guide is intended as a reference and a resource that trainers can use to incorporate HTSP information into current or planned training activities as part of pre-service, in-service or continuing education for health care providers working in maternal child health; reproductive health and family planning; well-baby and child health programs; cervical cancer screening programs; HIV prevention, care and treatment; immunization programs; malaria prevention programs; youth services; or men’s services, among others. It can also be used by trainers and programs to build community support for and acceptance of the delay of first pregnancy and improved pregnancy spacing practices through increased use of FP.
