"Every year, teachers would have an objective grading system to see how they did. Thus, they could compare teaching techniques from one year to the next. So if they experimented with some new system or assignment, they could immediately see the results. Not only that, but students could track their improvement from one year to the next. " This would show how they should improve.



"With the usual letter grading, especially in an era of widespread grade inflation, it's tough to identify which kids are reall gifted in certain areas. For example, if a 1/3 of the glass has gotten straight A's in all math classes, how do you know if it's a result of too easy of grading and/or having some truly smart future mathematicians? A standardized test would allow a comparison with students at a national level, free from the biases and grade inflation of local teachers." This would show where certain children are exceptional.
