How often are our assessments affected by nothing more or less than timing?
This comic made me think of my two favorite quotes in regards to grading:
A mark or grade is an inadequate report of an inaccurate judgement by a biased and variable judge of the extent to which a student has attained an indefinite amount of material. (Paul Dressel)
What grades offer is spurious precision, a subjective rating masquerading as an objective assessment. (Alfie Kohn)
