A Master of Science degree (Latin:Magister Scientiae; abbreviated M.S., MS, M.Sc., MSc, M.Sci., MSci, S.M., Sc.M., or Sci.M.) is a type of master's degree awarded by universities in many countries. The degree is usually contrasted with the Master of Arts degree. The Master of Science degree is typically granted for studies in sciences, engineering, and medicine, and is usually for programs that are more focused on scientific and mathematical subjects; however, different universities have different conventions and may also offer the degree for fields typically considered within the humanities and social sciences. While it ultimately depends upon the specific program, individuals who pursue a Master of Science degree typically require a thesis.
