To someone familiar with both the Italian and the U.S. college systems, Italian grades are best translated into American grades (and vice versa) according to the following table:
Scuola primaria, scuola secondaria di primo e secondo grado
For ordinary exams, universities in Italy use a 30-point scale that can be divided into failing (0 to 17) and passing (18 to 30 cum laude) grades. For final assessment of the entire degree, a 110-point scale is used, which is divided into two as well, with 66 being the minimum for a degree to be awarded. The 110-point scale incorporates scores both on course exams and for the final thesis. For outstanding results, lode, "praise" or "cum laude," is added to the maximum grade.
