Laudatur grades achieved before 1996 are now counted as eximia cum laude approbaturs.
Master's theses are typically graded with either the above scale, or by the Latin system used in high school matriculation exams, see above.
Contrary to the upper secondary school however, the grade laudatur is typically used very rarely (significantly less than 5% of theses).
Indeed, laudatur is often reserved for exceptional students and it is typically awarded for a thesis only once in 5 to 10 years.
Doctoral theses are usually evaluated by pass or fail, although some universities use the Latin system, or the scale from 0 to 5.
