The Diploma accreditation can be done for USP only, and is explained in Chapter V, Articles 100 to 106, of the Regulations of Graduate Study at USP.
Also, the titles of Master and PhD obtained abroad may be accepted as equivalent to the ones obtained at USP, pending the Curricular Chamber (CaC) evaluation and Council of Graduate Studies (CoPGr from Portuguese).
The starting analysis of the documentation, in order to obtain the accreditation of Master or PhD titles is conducted by the Graduate Programs Commission (CPG) of the institute where the applicant is enrolling to.
The Diploma accreditation is a procedure that must be accompanied by the relevant documentation.
