The academic grading system in Latvia has recently been changed to a ten-point scale, where "10" (Latvian: desmit) is the highest achievable grade, and "1" (Latvian: viens) is awarded for extremely poor performance. The minimal passing grade is "4" (Latvian: četri) to get the "4", you must acquire at least 50% correct on the work you hand in. Though some universities have a minimum passing grade of "5" (Latvian: pieci).
The absence of any kind of performance is indicated by "nv" (Latvian: nav vērtējuma 'no assessment possible'); in the past, the mark for absence of work was "0" (Latvian: nulle). Teachers in lower classes and for minor assignments in higher classes are encouraged to award one of two grades: "i" (Latvian: ieskaitīts 'counted') for a passing grade, and "ni" (Latvian: neieskaitīts 'not counted') for a failing grade. The grade of 10 is reserved for exceptional achievements. 9 is most commonly used for a United States equivalent of an A.
