Evaluate rubric examples for your planned assignment by figuring point value for performance indicators. The point value is typically across the top. The most common rubrics used are called "six-point" or "four-point" rubrics because they offer an equitable numeric translation for the purposes of converting a rubric score into a numeric grade. However, you might adjust scaling to whatever you like as long as there is a difference in point value between levels of achievement. For example, on a four point rubric, a "four" score indicates advanced proficiency, a "three" indicates proficiency, a "two" indicates partial-proficiency and a "one" equals not proficient. Students typically then receive a numeric score from one to four in any number skill indicator areas.
Read and evaluate rubric language to make sure it is easily comprehensible for students of all levels. Rubric language should be clear and precise with each level building progressively on the skills of the previous level as point value increases accordingly. For example, a partially proficient Language Arts paper rubric might state, "Student has multiple technical errors and lacks evidence of proofreading." A proficient Language Arts paper rubric might state, "Student has few if any technical errors and evidence of a thoroughly edited rough draft." Keep the language clear enough that students can follow its meaning, but detailed enough that there is an obvious difference between each level of proficiency.
Use assignment performance indicators and district or state standards to determine whether an existing rubric meets student achievement goals. Rubrics exist to clarify expectations for specific assignments. However, their ultimate goal is to assist students in learning how to perform skills and produce work required by the district and state proficiency levels. Cross reference any rubric against the state standards to make sure the proficiency level descriptors are in line with what students will be expected to do on state examinations. Also, verify that all expectations on the rubric are in line with assignment, classroom, grade level and district level performance indicators.
