1. A non-transitory computer-readable medium storing instructions that, when executed by a processor, are configured to cause the processor to perform operations for grading an electronically administered assessment, the operations comprising: displaying a first challenge problem; displaying a digital ink stroke corresponding to an answer to the first challenge problem from a first assessee; receiving, from an assessor via a digital pen, a first feedback tag for association with the digital ink stroke of the first assessee; electronically tagging the digital ink stroke of the first assessee with the first feedback tag made by the assessor via the digital pen; identifying a second digital ink stroke corresponding to an answer to the first challenge problem from a second assessee that matches the electronically tagged digital ink stroke of the first assessee; automatically tagging the matched digital ink stroke of the second assessee with the first feedback tag made by the assessor via the digital pen, wherein each digital ink stroke comprises a notation spatially defined relative to the first challenge problem; and removing the automatically tagged and matched digital ink stroke of the second assessee from a set of answers still requiring assessment by the assessor.

The non-transitory computer-readable medium of claim 1 , wherein the operations further comprise: determining a sequence of digital ink strokes corresponding to answers to the first challenge problem from each of a plurality of assessees to be displayed for assessment by the assessor, wherein the sequence includes the first digital ink stroke, the second digital ink stroke and each digital ink stroke of a set of at least one additional digital ink strokes, including at least a third digital ink stroke; and removing digital ink strokes from the sequence that have been matched and tagged with a feedback tag prior to their being displayed for assessment by the assessor.
