Letter Grades Versus Percentage Grades
So obviously knowing that a student scored 75 percent is a bit more
Hello I'm Milo for About.com and today we're talking about letter grades versus percentage grades.The biggest difference between letter grades and percentage grades is that the percentage is a bit more precise marker of how a student did against what is considered a complete or perfect score. For instance, after you have calculated the percentage grade you then round it into a letter grade.A typical letter grade system is:So obviously knowing that a student scored 75 percent is a bit more precise than knowing a student got a C. This is why some systems incorporate pluses and minuses, such as C plus or A minus. Some consider the rounding to a letter grade to be unhelpful. Especially when F, for instance, sounds so final. It is hard not to take it as a personal evaluation. To get around that some systems use E for effort instead or drop the letters altogether.However, on the bigger picture, while percentages are a bit more precise then letter grades, they are still giving the teacher same basic information. They are telling the teacher if the student successfully completed a task or not that has been broken down into discrete parts, like a quiz with 10 distinct questions or an essay with 5 distinct measures. These scores do not relay the depth of information necessary to teach a student at their point of need. They do not speak to a student's inherent intelligence, ability to think or comprehend, and of course should never be used to label a student's learning identity.For more information on education, check us out at About.com.
