Which master's degree counts for a PhD?

Short answer: An official second cycle degree (European level 7) that would let you start a PhD in your own country, with no "substantial difference" from an Italian master's (MUR circular). Each call lists the accepted degrees, so read it line by line.

• Bangladesh: an MS, MSc, MA or MBA after a 4 year honours degree is a master's. A 1 year master's after a 4 year honours degree is still a master's.
• Long single degrees such as medicine are often treated like a single cycle master's, but confirm with the program office before applying.
• A Master universitario (Italian short course) is not enough. It does not replace a Laurea Magistrale or an equivalent foreign master's.
• Field match: some programs accept any related master's; others ask for specific backgrounds. The committee also judges your fit through the research project.
