M.A

Master of Business Administration (MBA) is a two-year degree course in the field of management. In India, MBA degree can be awarded by any recognised university or by a business school affiliated to any university. Post Graduate Diploma in Management (PGDM) is a two-year Diploma course offered by the institutes that are recognised by the All India Council for Technical Education (AICTE) and which are autonomous and not affiliated to any university. It is not mandatory that a PGDM is equal to MBA. PGDM institutes accreditation by Association of Indian Universities (AIU) makes an institute's PGDM course equivalent to an MBA.
There are a large number of similarities between the curriculum of both MBA and PGDM. An MBA institute follows a fixed curriculum as it will be based on the university guidelines which occasionally may not be aligned to industry requirements. Autonomous institutes do not follow university standards, so they have the flexibility to align their curriculum according to industry standards and change in the business environment. PGDM from IIMs, XLRI, etc., has more value then MBA. However, MBA of FMS-DU, IIFT, etc., have a similar value as IIMs. Students are advised to choose the institute based on its ranking, not on the nomenclature of degree.
