This same thing happened to me. A few years agoI started a commercial project for my Spanish 2 students. Over the years, my rubric has become more restrictive because of previous students' inapprpropriate content. What I have noticed is that the commercials aren't anywhere near as interesting and creative as they were when my rubric was less detailed.
Does the rubric relate to the outcome(s) being measured
For each assessment, regardless of purpose, the assessor should organize the learning targets represented in the assessment into a written test plan that matches the learning targets represented in the curriculum
Annual state and local district standardized tests serve annual accountability purposes, provide comparable data, and serve functions related to student placement and selection, guidance, progress monitoring, and program evaluation.
As a "big picture" beginning point in planning for the use of multiple measures, assessors need to consider each assessment level in light of four key questions, along with their formative and summative applications1
I wish we could get away from grades and move to a benchmark checklist. When the student is proficient in one skill or concept they can move on to the next.
