Despite their widespread use, letter grades do not provide useful long-term pictures of student progress because they relate only to short-term success on defined bodies of taught content.

Assessments must be designed for the fundamental purpose of establishing and understanding where learners are in their long-term progress in an area of learning at the time of assessment.
