Academic grading in Mexico
- 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).
 Education in general
Grades are most often absolute and not class-specific. Thus, it may be that the top student of the class gets a low grade of 70, while the passing threshold is still 60. This is, curve-adjustment of scores is rare.
Students in honor roll are usually those with an overall grade point average of 90 (very good) or more upon graduation. In that case, depending on the school or university, the student may be awarded a "With Honors" diploma.
 Higher Education
In many universities, such as federal institutes of technology, an overall grade point average of 90 (very good) or better entitles the student to graduate with honors, other requirements such as a final work or thesis being waived, and automatically awards him or her the professional license (cédula profesional).
 Postgraduate Education
At this level, the minimum passing grade is still 70, but students are required to obtain a minimum grade of 80 to be awarded their postgraduate degree. Also, a score of 80 may be required to maintain other benefits such as a federal scholarship.
 Equivalences with other grading systems
Due to influence of North American television shows and media, the common US grading system that uses letters is understood in Mexico, and a rough equivalence can be made to the Mexican system, specially when television shows are localized for the Mexican audience.

For example, "a straight-A student" may be translated as un estudiante de puro 10, or "a straight-10 student".
Other grading systems, such as those used in European countries, or the United States GPA values 0.0–4.0, are less known.
