Academic grading in Mexico

Academic grading in Mexico employs a decimal system, from 0 to 10, to measure the students' scores. The grades are:^[1]

• 10: Excellent (excelente)
• 9: Very Good (muy bien)
• 8: Good (bien)
• 7: Average (regular)
• 6: Sufficient (suficiente)
• 0–5.9: Insufficient/Failed (deficiente/reprobado)

Since decimal fractions are common, a scale from 0 to 100 is often used to remove the decimal point. Then, 100 becomes the highest score, and 60 the minimum passing score. Depending on the school, the official certificate may use the range 0–100, or these may be converted back to the range 0–10, allowing for some rounding and truncation.

Although the grades 0–59 are normally given in class or tests, they are not reported as such in certificates. When failed subjects are reported in written, they normally have a score of NA or N/A, standing for No Acreditada (Not Accredited) or No Aprobada (Not Approved).

Major works, such as a written thesis or doctoral dissertation, may not have a grade, but appear in certificates simply as AC, standing for Acreditada (Accredited).

Occasionally, institutions, specially private schools, may use their own grading system, but there must exist conversion rules to convert those grades to their equivalent in the decimal system.
