What Is Assessment Reliability?
When we talk about assessment reliability, we are talking about the consistency with which different educators (or the same educator over time) administer, score, and analyze work. Is there agreement on what proficiency and proficient work looks like? Is there agreement on what the different levels of performance (as described in the rubric) look like in student work? Is the process used to identify student learning strengths and gaps and determine instructional strategies to be used to address the gaps? Is the process used to identify gaps in the task itself and determine ways to strengthen the task to improve the quality of student work that is produced? This agreement is achieved through a calibration process, conducted within a group of teachers.
