he CMAA PGS allows students to grade over time while still maintaining high standards, in fact there is an argument that the standard required using the CMAA PGS is higher as students must
pass every technique in order to achieve the next grade unlike standard gradings where a set score is
required. However if a student has been signed off almost all of the grade requirements but is still struggling with a couple of techniques the grade may be awarded with these techniques being deferred
and then re-visited at a later date, unlike a standard grading whereby these techniques would simply
receive a fail score and possibly be left behind. The Instructor can then require the student to
demonstrate once again prior to awarding a higher grade.
