How to score with the NM-MSSA Argumentative Writing Rubric, Grades 6–8.
A practical guide for teachers and norming teams. How to apply each descriptor consistently, the pitfalls that hurt inter-rater reliability, and a workflow for calibrating with colleagues.
Five traits, two rubrics, scored independently
- Score Production of Writing first (Development/Content 1-4, Organization/Focus 1-4, Language 1-4). Then score Use of Conventions (Grammar/Usage 1-3, Mechanics 1-3). Sum for a total out of 18.
- Each trait is scored independently. A response can earn 4 on Development but 2 on Language.
- The Use of Conventions rubric is shared across all grades 3 through 8. Its 3-point scale does not change by grade band.
Counterclaims apply starting in grade 7
- The alternate or opposing claims bullet under Organization/Focus is marked with an asterisk in the NM source rubric: it is only assessed at grades 7 and 8.
- Grade 6 argumentative responses are not penalized for omitting an acknowledgment of an alternate or opposing claim.
- At grades 7 and 8, scoring Organization/Focus at 4 requires substantial acknowledgment of alternate or opposing claims.
Common pitfalls to avoid
- Letting a strong claim halo weak source use. Development/Content at Score 4 requires consistently logical reasons, relevant evidence, AND accurate and credible sources.
- Penalizing surface errors under Development/Content. Grammar and Mechanics each have their own 3-point trait on the Use of Conventions rubric.
- Confusing cohesion with general fluency. Language at Score 4 specifically evaluates words, phrases, and clauses that clarify relationships among claim, reasons, and evidence.
Tips for norming with your team
- Anchor with 3 to 5 sample responses scored by your most experienced grader before the session.
- Score the first 5 silently, then compare. Discuss any trait where graders are more than one point apart.
- Re-norm halfway through a long batch. Drift is real.
Notes for the NM-MSSA Argumentative Writing Rubric, Grades 6–8
NM-MSSA Grades 6-8 Argumentative scores argument-genre writing on the same 5-trait structure used at the elementary level. The descriptor language is argument-specific. Development/Content scores the claim, reasons, evidence, sources, and topic understanding. Organization/Focus scores the introduction, conclusion, logical organization of reasons and evidence, and acknowledgment of alternate or opposing claims (grades 7-8 only).
Alternate and opposing claims are evaluated beginning in grade 7. The bullet is marked with an asterisk in the source rubric. Grade 6 argumentative responses are not penalized for omitting a counterclaim acknowledgment.
Responses are scored on three Production of Writing traits plus the two shared Use of Conventions traits (Grammar/Usage, Mechanics). Maximum total is 18 points.
The Use of Conventions rubric is identical across all NM-MSSA grades 3 through 8 and applies whether the writing task is opinion, informative, narrative, or argumentative.

Why phones should be allowed in middle school classrooms
Middle schools across New Mexico have different rules about phones in class, and the debate is not going away. Middle schools should allow students to bring personal phones to class for academic use because they can serve as research tools, they support student accessibility needs, and clear guidelines can address concerns about distraction.
Research and learning tools
Source 1 explains that more than 80 percent of middle schoolers have access to a personal phone, but only about 35 percent are allowed to use them during class. The same source describes a science teacher in Las Cruces who uses students' phones to run quick polling activities, take photos of lab setups, and look up scientific terms in real time. When schools rely on shared Chromebook carts, those activities take longer and reach fewer students.
Accessibility for students
Source 2 reports that phones offer features that support accessibility, including text-to-speech, voice notes, and reminders. For students with reading challenges or executive-function needs, these tools can be the difference between participating fully and falling behind. Source 1 cites a similar example of a 7th grader who uses phone reminders to track assignments after her family moved to a new district mid-year. Without her phone, she would have missed several deadlines.
Addressing concerns about distraction
Some teachers and parents worry that phones distract students. Source 2 acknowledges this concern and points to two schools that piloted classroom phone use with clear, visible guidelines: phones face-down during lectures, used only when the teacher prompted, and confiscated for the day if used for social media. Distraction is a real risk, but it is a classroom-management issue, not a reason for a blanket ban. Both pilot schools reported that academic phone use improved and that disciplinary incidents stayed flat or dropped slightly.
Conclusion
Phones already exist in students' lives. Banning them outright wastes a powerful learning tool, ignores accessibility needs, and treats students as if they cannot follow classroom guidelines. Middle schools should set clear expectations and let students use their phones for academic work.
Claim and evidence fully addressed
Claim fully addresses the topic. Argument is developed with three consistently logical reasons (research, accessibility, distraction management) and relevant evidence from both sources. Specific facts (80 percent access, two pilot schools) show substantial topic understanding.
Clear intro, counterclaim addressed, cohesive
Clear and engaging intro. Reasons and evidence are consistently organized logically. Alternate view (distraction) substantially acknowledged in paragraph 4 (asterisk requirement met for grade 8). Language uses precise words and clauses to clarify relationships. 4 + 4 = 8 of 8.
Full command of conventions
Grammar and usage are correct throughout. Conventions including punctuation, capitalization, and spelling are correct, with only minor errors that do not interfere with meaning. Earns full credit on both 1-3 Use of Conventions traits, 3 + 3 = 6 out of 6.
