The Sanam Luang National Dhamma Studies Examination Curriculum is a three tier system used throughout Thailand for training in theoretical knowledge about Buddhism. The curriculum is run in tandem with the nine-tiered Pahrian Thamm curriculum for Pali Studies. The curriculum offers two slightly different sets of examination papers - Nak Thamm designed for the ordained Sangha i.e. Buddhist monks, novices and nuns) and Thammaseuksa designed for lay Buddhists. Tuition for the Nak Thamm and Thammaseuksa curricula and the examinations themselves take place throughout Thailand annually. Thammaseuksa tuition and examinations are also held in some Thai temples outside Thailand.
