Titles
See also: List of master’s degrees
Master’s degrees are commonly titled using the form ‘Master of …’, where either a faculty (typically Arts or Science) or a field (Engineering, Physics, Chemistry, Business Administration, etc.) is specified. The two most common titles of master’s degrees are the Master of Arts (MA/M.A./A.M) and Master of Science (MSc/M.Sc./M.S./S.M.) degrees, which normally consist of a mixture of research and taught material. # ISO certification in India
The title of Master o f Phi losophy (MPhil) indicates (in the same manner as Doctor of Philosophy) an extended degree with a large research component.Other generically named master’s programs include the Master of Studies (MSt)/Master of Advanced Study (MASt)/Master of Advanced Studies (M.A.S.), and Professional Master’s (MProf). Integrated master’s degrees and postgraduate master’s degrees oriented towards professional practice are often more specifically named for their field of study (“tagged degrees”), including, for example, Master of Business Administration, Master of Divinity, Master of Engineering, Master of Physics, and Master of Public Health. # ISO certification in India
The form “Master in …” is also sometimes used, particularly where a faculty title is used for an integrated master’s degree in addition to its use in a traditional postgraduate master’s degree, e.g. Master in Science (MSci) and Master in Arts (MArts). This form is also sometimes used with other integrated master’s degrees and occasionally for postgraduate master’s degrees (e.g. Master’s in Accounting). Some universities use Latin degree names; because of the flexibility of syntax in Latin, the Master of Arts and Master of Science degrees may be known in these institutions as Magister artium and Magister scientiæ or reversed from the English order to Artium magister and Scientiæ magister. Examples of the reversed usage include Harvard University and the University of Chicago, leading to the abbreviations A.M. and S.M. for these degrees. The forms “Master of Science” and “Master in Science” are indistinguishable in Latin.Courtesy :

In the UK, full stops (periods) are not commonly used in degree abbreviations. In the US, The Gregg Reference Manual recommends placing periods in degrees (e.g. B.S., Ph.D.), while The Chicago Manual of Style recommends writing degrees without periods (e.g. BS, PhD).
Master of Science is generally abbreviated M.S. or MS in countries following United States usage and MSc or M.Sc. in countries following British usage, where MS would refer to the degree of Master of Surgery. In Australia, some extended master’s degrees use the title “doctor”: Juris doctor and Doctors of Medical Practice, Physiotherapy, Dentistry, Optometry and Veterinary Practice. Despite their titles these are still master’s degree and may not be referred to as doctoral degrees, nor may graduates use the title “doctor”. # ISO certification in India
