Hii There,

The Management Aptitude Test (MAT) is a standardized examination that has been conducted since 1988. Its primary purpose is to assist Business Schools (B-Schools) in assessing candidates for admission to MBA and related programs. In 2003, the Government of India, under the Ministry of HRD, granted approval for MAT to be recognized as a national-level test.
