upasampadā

thumb|Upasampadā of a Buddhist monk in Burma Upasampadā (Pali) literally denotes "approaching or nearing the ascetic tradition." In more common parlance it specifically refers to the rite and ritual of ascetic vetting (ordination) by which a candidate, if deemed acceptable, enters the community as upasampadān (ordained) and is authorised to undertake ascetic life.

According to Buddhist monastic codes (Vinaya), a person must be 20 years old in order to become a monk or nun. A person under the age of 20 years cannot undertake upasampadā (i.e., become a monk (bhikkhu) or nun (bhikkhuni)), but can become a novice (m. samanera, f. samaneri). After a year or at the age of 20, a novice will be considered for upasampadā.
