Assessing for achievement occurs when teachers evaluate the quantity of work completed accurately. Instead of identifying the ideas that the student has mastered, these assessments focus on comprehensive scores that communicate the percent of assessment items the student answered correctly. There are shortcomings with this assessment approach, such as the ambiguity of the comprehensive scores. What does it mean if a student scores 50% on a test? Which 50% of the material do they know? How close are they to mastering the other 50%?
This type of measurement doesn’t help stakeholders understand what a student has mastered, instead only how much a student has achieved. In many ways, these comprehensive measures may miscommunicate student performance, leading to students labeling themselves negatively instead of focusing on the growth they have achieved.
Teachers assess achievement when they focus on the completion of learning tasks over the mastery of learning goals.
