The 1-8 Scoring Scale
Understanding the 1-8 Scoring Scale
Beginning in 2026-27, all BSD secondary courses use a common 1-8 scoring scale to communicate student learning. Prior, three BSD Middle Schools, the International School of Beaverton, and Mountainside High School all used a 1-8 scoring scale. Now all BSD secondary schools will use a common scale. BSD elementary schools will continue to use a 1-4 scale.
The 1-8 scale is different from a traditional points or percentage system. A score represents the level of learning demonstrated in student evidence in relation to a course learning target and its rubric.
Students are evaluated against the criteria described in the rubric, not compared with the performance of other students.
How do Banded Rubrics Work?
Rubrics describe what student learning looks like at different levels of understanding. On the 1-8 scale, rubric descriptors are organized into four bands:
| 8/7 | 6/5 | 4/3 | 2/1 | |
| Criterion | Evidence shows accurate, consistent, and flexible understanding of the learning target. The student applies the same knowledge and skills in familiar situations and can transfer, connect, or apply them effectively in new or unfamiliar situations. Reasoning and conclusions are well supported with relevant evidence, representations, words, or numbers. | Evidence shows accurate and consistent achievement of the learning target in expected or familiar situations. The student applies the relevant knowledge and skills and supports their thinking with appropriate evidence, reasoning, representations, words, or numbers. | Evidence shows achievement of some aspects of the learning target, but performance is not yet accurate or consistent across the target. The student can apply some relevant knowledge and skills in familiar situations, but gaps, errors, or incomplete reasoning are still evident. | Evidence shows emerging elements of the learning target, with substantial gaps or misconceptions still present. The student demonstrates some relevant knowledge or skills, but the evidence does not yet show consistent or successful application of the target. |
Teachers compare the evidence a student provides with the descriptors in the rubric and determine which band best represents the learning demonstrated.
The two numbers within each band allow the teacher to make a more precise determination of the student's performance within that level.
An Example
Imagine a learning target asking students to use evidence to support a conclusion.
| 8/7 | 6/5 | 4/3 | 2/1 |
| Uses multiple relevant pieces of evidence and explains how the evidence supports the conclusion | Uses relevant evidence to support the conclusion and explains the connection | Uses evidence connected to the conclusion | Identifies evidence related to the topic or question |
The language of an actual rubric will vary by course and learning target, but the structure is the same: each band describes what student evidence shows at that level of learning.
How does a teacher determine a score?
Student work does not always fit perfectly into a single rubric description.
A student may demonstrate some characteristics described in one band and other characteristics described in another. Teachers consider the evidence as a whole and use their professional judgment to determine the descriptor, and score, that best represents the student's current level of learning. This is sometimes called a best-fit approach.
A rubric is therefore not intended to function as a checklist in which a certain number of completed items automatically produces a score. The teacher's role is to evaluate the quality and meaning of the evidence in relation to the learning target.
A score on the 1-8 scale is not a percentage
A score of 6 does not mean 6 out of 8 points, or 75%.
The numbers on the 1-8 scale identify levels described by the rubric. They are not fractions of a total number of points.
For example, a student receiving a 6 has demonstrated learning that aligns with the 6/5 band of the rubric. The score communicates what the student's evidence shows, not the percentage of points the student earned.
Because the two systems communicate different information, converting an individual 1-8 score into a percentage does not accurately represent the student's learning.
Why use the same 1-8 scale across secondary courses?
Using a common scoring structure provides students and families with greater consistency across courses and schools while still allowing rubrics to reflect the learning that is specific to each subject.
A common scale helps:
- Clarify expectations. Students can see what learning looks like at different levels.
- Provide useful feedback. Rubric descriptors help students understand what they have demonstrated and what they are working toward next.
- Support consistency. Teachers across secondary schools use the same 1-8 scoring structure even though the specific learning targets and rubric criteria differ by course.
- Keep the focus on learning. Scores represent evidence of what students know and can do in relation to identified learning targets.
One assignment can provide evidence for more than one learning target
Many authentic classroom tasks involve several kinds of learning at the same time.
For example, an English essay might provide evidence of a student's understanding of the text, organization of ideas, and use of language. A science investigation might provide evidence of content understanding, analysis of data, and scientific reasoning.
A single assignment can therefore provide evidence for multiple learning targets. When this occurs, teachers consider and score the evidence related to each learning target separately.
This allows one rich learning task to communicate several specific pieces of information about what a student knows and can do.
What should families look for?
When reviewing scores with your student, consider asking:
- What learning target was this assignment assessing?
- What does the rubric say about the evidence at this level?
- What did your work demonstrate?
- What feedback did you receive?
- What are you working on next?
The goal of the 1-8 scale is not simply to provide a number. The score, rubric, and teacher feedback work together to provide a clearer picture of student learning.
