The NCT is a British charity that helps people through pregnancy, birth, and the first months with a baby. In the UK it is well known for antenatal classes (classes before the baby comes) and for local groups of new parents. The letters stand for National Childbirth Trust: national = of the country, childbirth = having a baby, trust = a kind of charity, not a hospital and not a government office. You will see NCT in British newspapers, parenting websites, and everyday talk among parents in Britain. Taiwanese readers rarely need it unless they are reading UK material. Though actually, many people in Britain now just say the letters and would have to think for a second to recall the full name.
