3 Conventions

- capitalization at the beginning of the majority of thought units
- end punctuation for majority of thought units
- one complete sentence that expresses an idea with subject-verb agreement Ex: "The dog runs."

How to score with the Maine MEA Argumentative Writing Rubric, High School.
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.
Three elements, scored independently
- Score Organization, Idea Development, and Conventions independently on a Full / Partial / Limited / Unrelated evidence scale.
- Each element is read against the specific bullet criteria at each evidence band. The response must include the bulleted items at a band to earn that band's score.
- There is no composite score in the rubric. Per-element scores are the rubric output.
Two rational reasons at Full Evidence
- Organization at Full Evidence specifically requires two rational reasons in both the introduction and the conclusion. A response with one well-developed reason caps at Partial Evidence on Organization.
- The same two-reasons-and-evidence structure carries into Idea Development at Full Evidence: one piece of relevant evidence follows each of the two reasons.
- Three or more reasons do not earn extra credit but do not cap the score. Two is the rubric minimum at Full Evidence.
Common pitfalls to avoid
- Capping a strong essay at Partial Evidence on Organization because the conclusion does not restate both reasons. The rubric explicitly requires this at Full Evidence.
- Counting personal anecdote as evidence. The Maine MEA HS rubric does not specify source-based evidence, but the evidence must follow each reason and be relevant to the claim.
- Forgetting that Maine MEA HS argumentative does NOT include a counterargument expectation. A response is not penalized for omitting one.
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 element where graders are more than one band apart.
- Re-norm halfway through a long batch. Drift is real.
Notes for the Maine MEA Argumentative Rubric, High School
Maine MEA at High School shifts from the Grades 6-8 expository modes (compare/contrast, cause/effect, problem/solution) to argumentative writing. The structure of the rubric stays the same (three elements, four evidence bands) but the descriptor language now focuses on claim, reasons, and evidence.
Organization at Full Evidence explicitly requires two rational reasons in both the introduction and the conclusion. Idea Development at Full Evidence requires evidence for each of the two reasons, plus connecting words. A response with one strongly developed reason will typically cap at Partial Evidence on both Organization and Idea Development.
The Maine MEA HS argumentative rubric does NOT include a counterargument or alternate-argument expectation. Unlike STAAR (Grades 8-EII) or KAP (High School), Maine MEA does not specifically reward addressing opposing views at high school. A response is scored on its claim, reasons, and evidence only.
Maine MEA publishes a Level 2 version of the HS rubric in addition to the Level 3 version shown here. Level 2 Organization at Full Evidence requires only an introduction that states the claim and a rational reason (one reason, not two), and a conclusion that states the claim and the rational reason.

Why our high school should adopt universal free lunches
When students worry about whether they can afford lunch, they spend less mental energy on the rest of the school day. Our high school should adopt a universal free lunch program for two rational reasons: it removes a visible source of social stigma from low-income students, and it simplifies the administrative burden of running a tiered eligibility system.
Reason one, reducing social stigma
Students who currently qualify for free or reduced lunch are often visibly separated from peers who pay full price. The line at the cafeteria, the swipe of a different card, the unspoken knowledge of who is on the program: each of these is a small daily reminder of family income. Universal free lunch removes this distinction by making everyone equally eligible. A 2019 study from the Urban Institute found that participation in school lunch programs rose 9 percent when stigma was removed, and that overall attendance also improved modestly.
Reason two, simpler administration
Running a tiered eligibility system requires verifying family income, processing applications, recertifying every year, and managing the paperwork for households whose income changes mid-year. A universal program collapses all of this to a single rule: every student gets lunch. Districts that have made the switch report meaningful reductions in administrative time for front-office staff and cafeteria managers.
Conclusion
Our high school should adopt a universal free lunch program for two rational reasons: it removes a visible source of social stigma from low-income students, and it simplifies the administrative burden of running a tiered eligibility system. Both reasons are supported by experience at districts that have already made the change. The case is strong and the implementation is straightforward.
Claim with two reasons in intro and conclusion
Introduction states the claim (universal free lunch) and supports it with two rational reasons (stigma reduction, administrative simplicity). Body includes both reasons. Conclusion restates the claim and both reasons. Matches Full Evidence on Organization at High School.
Evidence follows each reason, connecting words throughout
One piece of relevant evidence follows each reason (Urban Institute 9 percent finding for stigma, district reports of reduced administrative time). Connecting language links reasons to evidence in both body paragraphs. Matches Full Evidence on Idea Development.
Capitalization and punctuation throughout
Capitalization at the beginning of every thought unit. End punctuation for all thought units. Multiple complete sentences with subject-verb agreement, including complex constructions. Matches Full Evidence on Conventions for a high school response.
