For example, if the primary tumor grade was 2 and the secondary tumor grade was 3 but some cells were found to be grade 4, the Gleason score would be 2+4=6. This is a slight change from the pre-2005 Gleason system where the second number was the secondary grade (i.e., the grade of the second-most common cell line pattern).
AES machines, however, appear to be less reliable than human readers for any kind of complex writing test. [29] In current practice, high-stakes assessments such as the GMAT are always scored by at least one human. AES is used in place of a second rater. A human rater resolves any disagreements of more than one point. [30]
A rubric is a tool used in writing assessment that can be used in several writing contexts. A rubric consists of a set of criteria or descriptions that guides a rater to score or grade a writer. The origins of rubrics can be traced to early attempts in education to standardize and scale writing in the early 20th century.

In contrast to the original Gleason grading system, it is now recommended that on a needle core biopsy both the most common and highest grade are added together for the Gleason score [2]. For example, if there is 60 % Gleason pattern 3, 35 % Gleason pattern 4, and 5 % Gleason pattern 5, the Gleason score would be 3 + 5 = 8.
From the 10th grade onwards, including tertiary education, a 20-point grading scale is used, with 10 passing grades and 10 failing grades, with 20 being the highest grade possible and 9.5, rounded upwards to 10, the minimum grade for passing. This 20-point system is used both for test scores and grades.
The top grade, A, is given here for performance that exceeds the mean by more than 1.5 standard deviations, a B for performance between 0.5 and 1.5 standard deviations above the mean, and so on. [17] Regardless of the absolute performance of the students, the best score in the group receives a top grade and the worst score receives a failing grade.
