Until the Tang Dynasty, the term "Chánshī" (禅师; Dhyana Master) was regularly used for a monk who was a master of chan, or meditation, versus those who specialized in Dharma (scriptural teachings) and Vinaya (discipline and moral precepts). This included several important figures who were later not considered to be part of the "Chán school" per se, such as Tiantai Master Zhiyi.

In contemporary China, the term "Chán" (禪), being simply one of many terms for forms of meditation, is not limited to the Chán school alone. Neither the majority of monastics nor lay people are formally tied to a given "school" of Buddhist practice, which is different to the situation in Japan. It is only those senior and experienced practitioners who receive such transmission into the Chán school. Most temples belong to the Chán school in name, but also embrace other teachings including those of Tiantai, Pure Land, Huayan, and Yogacara schools, often under the umbrella term "Chinese Buddhism" (中国佛教). This has been the norm for the past 1000 years, since the Song Dynasty.

While there are no official organizations to regulate the use of honorary titles, "chánshī" is used as a title of respect for an adept, typically a monk, who specializes in Chán. "Chánzōng Dàshī" (禅宗大师; Great Master of the Chán School) is a similar and more specific honorary term, though rather rare.

The more common term when addressing a Buddhist master is "Shīfu" (师父; Master), which is also used for any monk as a matter of respect. Strictly speaking, this term, which includes the relational term for "father" (父), refers more to one's own teacher or preceptor. The term "Făshī" (法师), meaning "Dharma teacher", is more generic, and is used both by lay Buddhists and also by Buddhists monastics themselves. The general term "Lǎoshī" (老师; Teacher) is also used to address a master as one's teacher, but this term is a general one, so much so that it is used for a teacher of any subject.

There is no standard official title for "Zen Master" across the various Zen traditions in Japan. Various titles may be used:

• "Shike" is used for a select group of people, both in Rinzai and Soto, who are qualified to supervise the training of priests-to-be in the sodos, the training halls.
• "Rōshi" ("old teacher") is traditionally an honorific title given to older monks and Zen teachers in Japan, though both "sensei" and "roshi" have come to denote official or semi-official ranks within some Zen schools in Japan, the United States and Europe.
• "Sensei" (simply "teacher") is often applied in addressing the Zen teacher or "master".
• "Oshō", "virtuous monk/priest" is used for trainees who have acquired a basic level of priesthood.

Sōtō

In Sōtō Zen, the title "Dai-Osho" is the highest priestly rank in a clear monastic hierarchy. It is only surpassed by "Zenji" which is only applied to Dōgen and Keizan (the founders of the school), and to the current or former abbots of the two head temples of the sect. To supervise training monks, further qualifications are required:

The relatively low status of dharma transmission means that in and of itself it does not qualify one to accept students or to train disciples. According to the regulations, Zen students should be supervised only by a teacher who has attained supervisory certification (i.e. sanzen dōjō shike status), that is, someone who in the popular literature might be called a Zen master. To attain supervisory certification requires not just high ecclesiastical grades and dharma seniority but also at least three years' experience as an assistent supervisor at a specially designated training hall (tokubetsu sōdō), during which time one undergoes an apprenticeship.

Rinzai

In Rinzai too, further training is needed to be qualified as a supervisor. The common transmission does not include inka shōmei. Ideally inka shōmei is "the formal recognition of Zen's deepest realisation", but practically it is being used for the transmission of the "true lineage" of the masters (shike) of the training halls. Training halls are temples which are authorised for further training after being qualified as a temple priest.

There are only about fifty to eighty of such inka shōmei-bearers in Japan:

In Rinzai Zen, it is relatively easy to say who is a roshi and who is not. Anyone who is authorized by another roshi (i.e. his teacher) is a roshi. This authorization (officially the "inka-shômei" document) is documented on a piece of paper, that is why it is also called colloquially "ichi-mai", that is "one sheet (of paper)". The transmission is totally vertical from teacher to student, no peer control is involved. That means that the Rinzai sect has no means to control who is made a roshi and who is not. In spite of that, the number of Rinzai roshis is relatively low, maybe around 50 or so.

The shike is not married. He...

[H]as the prestige and generally owns the respect of being a true Zen master, a living symbol of the Zen monastic tradition, the quintessence of Zen virtues ideally incarnating wisdom, spirituality, strict discipline, individuality, and yet gentle social personality.

The shike is also the head of the sect (subschool of the Rinzai-school, with its own head temple). He appoints and dismisses the priests, and appoints the titles in the ranking system. Yet, "the position as abbot [at Myōshinji] is based on election, each elected period lasting four years".

Sunim is the Korean title for a Buddhist monk or Buddhist nun of any tradition, and does not denote any specific rank or qualification. It is considered respectful to refer to senior monks or nuns in Korea as Kun sunim, and this polite way of expressing the title can also denote some sort of realization on the part of the individual being addressed. In most Korean temples, a middle-aged monk assumes the role of a juji sunim, who serves administrative functions. The eldest sunim is typically seen as a symbolic leader of the younger sunims.

In Korean Soen, Inka (In'ga) typically refers to the private acknowledgement of dharma transmission from a teacher to their student. "Transmission" is used to refer to the public ceremonial version of the same acknowledgement. Both are considered equal in authority and "realization". A monk with either In'ga or the public "transmission" is qualified to hold the post of Soen Sa, or "Zen Master" for a temple, and give transmission to their own students (either, In'ga or public "transmission"). The majority of Zen Masters in Korea have only received, and only give In'ga, with the formal transmission ceremony being far more rare.

In the Kwan Um School of Zen, founded by Korean Zen teacher Seung Sahn in America and Europe, a Zen master can be referred to as a Soen Sa Nim ("Soen" or "Son" being Korean for Chan, or Zen) — although this term usually is used only in reference to Seung Sahn himself (usually with the honorific "Dae", meaning "great" - as in "Dae Soen Sa Nim").

"Zen master" has been used to refer to individuals hailing from any number of countries and traditions. It is not an exact translation of any title from the countries from which Zen traditions emanate, where titles vary widely, even in different traditions from the same country. Its usage has diminished among contemporary American Zen teachers and practitioners.

The term has entered popular culture and has been used to refer to any number of public figures in sports and entertainment, denoting a person who demonstrates detachment and control in stressful situations. It was sometimes adopted by figures in the spiritual counterculture of the 1970s and 1980s who had little or no actual Zen training ("Zen Master Rama," "Osho",) presumably to generate positive associations or legitimacy.
