A master's degree is the certificate that a person gets after he completes his bachelor's degree and continues to study in a university in some specific field. In other words, a person must first get his bachelor's degree before he can get a master's degree. These people are considered to possess more advanced knowledge of the field that they had studied, as compared to those who only get a bachelor's degree. There has recently been an increase in programs leading to these degrees in the United States. More than twice as many such degrees are now awarded, as compared to the 1970s. In Europe, most countries offer master's degrees in all fields.
