In the realm of US education, a rubric is a "scoring guide used to evaluate the quality of students' constructed responses" according to James Popham.
Typically presented in table format, rubrics contain evaluative criteria, quality definitions for various levels of achievement, and a scoring strategy.
They prove particularly beneficial when multiple evaluators are assessing to maintain focus on contributing attributes.
Modes appear in succession because their frequency is determined by four parameters: endemicity, performance rate, commitment strength, and acceptance.
The transition from medicine to education occurred through the construction of "Standardized Developmental Ratings" in the mid-1970s, later adapted for writing assessment.
