The minimum age for ordaining as a Buddhist monk is 20 years, which is calculated from conception. Those under this age can perform traditional ceremonies such as ''[[shinbyu]],'' in Myanmar, in order to ordain as novices ([[śrāmaṇera|sāmaṇera]]). Novices shave their heads, wear the yellow robes, and observe the Ten Precepts. While there is no explicit minimum age for novices prescribed in the scriptures, it is traditionally accepted that boys as young as seven can be accepted for ordination. This tradition echoes the story of the Buddha's son, Rahula, who was allowed to become a novice at the age of seven. Both monks and nuns are expected to adhere to a specific code of discipline, of which monks follow 227 rules, and nuns follow 311.

In most Theravāda countries, it is a common practice for young men to ordain as monks for a fixed period of time. In Thailand and Myanmar, young men typically ordain for the retreat during [[Vassa]], the three-month monsoon season, though shorter or longer periods of ordination are not rare. Traditionally, temporary ordination was even more flexible among Laotians. Once they had undergone their initial ordination as young men, Laotian men were permitted to temporarily ordain again at any time, though married men were expected to seek their wife's permission. Throughout Southeast Asia, there is little stigma attached to leaving the monastic life. Monks regularly leave the robes after acquiring an education, or when compelled by family obligations or ill health.

Ordaining as a monk, even for a short period, is seen as having many virtues. In many Southeast Asian cultures, it is seen as a means for a young man to "repay his gratitude" to his parents for their work and effort in raising him, because the merit from his ordination is dedicated for their well-being. Thai men who have ordained as a monk may be seen as more mature and suitable husbands by Thai women, who refer to men who have served as monks with a colloquial term meaning "ripe" to indicate that they are more mature and ready for marriage. Particularly in rural areas, temporary ordination of boys and young men traditionally offered peasant boys an opportunity to receive free education in temple schools with sponsorship and accommodation.

In Sri Lanka, temporary ordination is not practised, and a monk leaving the order is frowned upon but not condemned. The continuing influence of the [[caste system in Sri Lanka]] plays a role in the taboo against temporary or permanent ordination as a bhikkhu in some orders. Though Sri Lankan orders are often organized along caste lines, men who ordain as monks temporarily pass outside of the conventional caste system, and as such during their time as monks may act (or be treated) in a way that would not be in line with the expected duties and privileges of their caste.{{citation needed|date=July 2015}}

For those born in Western countries who wish to become Buddhist monks or nuns, it is possible to undertake the lifestyle in their home countries, among other Buddhist monastics in Western countries, or to travel and take up residence in a Buddhist monastery in Asian countries such as Sri Lanka or Thailand. In countries where Buddhism is deeply rooted, it can often be easier to adhere to the lifestyle of a monk or nun, as it requires considerable discipline to successfully live by the non-secular rules and regulations for which Buddhist practices are known. For instance, Theravāda monastics are typically required to abstain from activities such as working, handling money, listening to music and cooking. Such obligations can be especially challenging in non-Buddhist societies.{{citation needed|date=July 2015}}
