In the world of prospect scouting, the most widely accepted tool for evaluating players is the 20-80 scale. The scale, on which a score of 50 represents an average result, has standardized prospect scouting so that players across organizations can be compared with one, sometimes too-simplified score. Grades are often assigned to the individual "tools" or skills that players have. When it comes to position players, skills like hit, power, arm, speed, and field are often each assigned their own grade on the 20-80 scale, and the average is used to determine the prospects' overall value.
While it's difficult for a prospect to earn an overall grade much higher than 60 or 65 (Jesús Made is considered a 60-grade prospect), individual skills will occasionally earn scores of 70, 75, and in rare instances 80.
