What this rubric measures
The Maine MEA Expository Writing Rubric, Grades 6–8 is the official scoring guide used to evaluate student writing on Maine Educational Assessment assessments. It is an Analytic rubric that scores responses across 3 distinct criteria, allowing teachers to give precise, targeted feedback on each area of writing.
All 3 scoring criteria
Click any criterion to expand its score level descriptors. The language below is taken verbatim from the official Maine Department of Education Educational Assessment scoring guide.
1 Organization
The essay includes at a minimum:
- an introduction that states both parts of the problem
- body that includes a solution and refers to the problem
- a conclusion that states the problem and its solution
The essay includes at a minimum:
- an introduction that states one part of the problem
- a body that includes a related solution
- a conclusion that states the problem or the solution
The essay includes at a minimum:
- some evidence related to the specified topic (i.e., introduction, on-topic problem/solution relationship, or conclusion)
No evidence of organization.
Evidence is off topic.
Organization at Grade 8 expository requires the essay to address the specified topic with a solution related directly to the problem (problem/solution mode). Grades 6 and 7 use compare/contrast and cause/effect modes respectively, with mode-specific language at each band.
2 Idea Development
The essay includes at a minimum:
- one problem with a relevant detail
- one solution with a relevant detail
- one transitional word(s) that connects the problem to the solution
The essay includes at a minimum:
- one problem or solution with a relevant detail
- one transitional word(s) that is in relation to the problem or the solution
The essay includes at a minimum:
- one detail or word that describes the problem or the solution
No evidence of idea development.
Evidence is off topic.
Idea Development at Grade 8 expository requires the essay to develop the topic with details and transitional words. Grade 6 (compare/contrast) requires activities related to opposing conditions; Grade 7 (cause/effect) requires effects with relevant details.
3 Conventions
The essay includes more than one sentence and at a minimum:
- 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."
The essay includes at a minimum:
- capitalization at the beginning of one thought unit
- end punctuation for one thought unit
- one complete sentence with subject-verb agreement
The essay includes at a minimum:
- one use of standard English conventions (capitalization at the beginning of one thought unit, end punctuation for one thought unit or one thought unit with or without subject-verb agreement)
No evidence of standard English conventions.
Conventions at Grades 6-8 expository follows the same pattern as Grades 3-5: capitalization, end punctuation, and subject-verb agreement. Full Evidence requires capitalization at the beginning of the majority of thought units and end punctuation for majority of thought units.
How to score with the Maine MEA Expository 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.
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.
Mode shifts across Grades 6, 7, and 8
- Grade 6 expository is compare/contrast (two opposing conditions with activities for each). Grade 7 is cause/effect (effects related to a provided cause). Grade 8 is problem/solution (solution related directly to the problem).
- The three rubric elements are constant across the grade band; only the descriptor language inside each element changes to match the mode.
- A response that uses the wrong mode (e.g., a compare/contrast essay on a problem/solution prompt) typically caps Organization at Limited Evidence because the bulleted criteria are mode-specific.
Transitions are scored inside Idea Development
- Grades 7 and 8 explicitly require transitional words in Idea Development at Full Evidence. Grade 6 expects activities related to opposing conditions; transitions are implicit but not bulleted.
- A single transition word is enough at Grade 8 Full Evidence if it connects the problem to the solution. A response without any transition typically caps at Partial Evidence on Idea Development.
- Transitions count even if simple (so, because, therefore). The rubric does not require sophisticated connectors.
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 Expository Rubric, Grades 6–8
This page presents the Grade 8 Level 3 problem/solution rubric in full because it is the most developed of the three grades in the band. Grade 6 uses compare/contrast (Full Evidence Organization requires an introduction that presents two opposing conditions and a body that includes one activity common to both plus one activity related to each opposing condition). Grade 7 uses cause/effect (Full Evidence Organization requires an introduction that presents the cause and its effects, and a body that includes two effects referred to the cause).
Maine MEA publishes a Level 2 version of each grade's rubric in addition to the Level 3 version shown here. Level 2 versions use simpler criteria at each band (for example, Grade 8 Level 2 Organization requires only an introduction that states both parts of the problem and a body that relates how the solution can be applied).
Idea Development at Grades 7 and 8 explicitly requires transitional words at Full Evidence. Grade 6 expects activities tied to each opposing condition; the transition expectation is implicit in the compare/contrast structure but not bulleted.
The Conventions element at Grades 6-8 is similar to Grades 3-5 with the same Full Evidence criteria (capitalization, end punctuation, complete sentence with subject-verb agreement). Grade-level expectations for what counts as a complete sentence shift, but the rubric bullets do not.

Late-night phone use and a school-wide screens-down pledge
Walk into any first-period classroom and you can see who stayed up too late. The problem is that middle schoolers are losing sleep because of late-night phone use, and the school day starts before their bodies have caught up. One solution would be a voluntary school-wide screens-down pledge starting at 9 p.m., supported by a homeroom discussion at the start of each quarter.
The problem
Sleep scientists say middle schoolers need about nine hours of sleep per night, but most are getting closer to seven. The biggest single cause is phone use after bedtime: scrolling, messaging, and watching short videos. The light from screens delays the release of melatonin, and the social pull of group chats keeps students up well past midnight. The next morning, focus is impossible.
The solution
A voluntary screens-down pledge would not solve everything, but it would name the problem and give students a shared goal. If even half the students agreed to put phones away by 9 p.m., the social cost of staying up would shift, because group chats would slow down naturally. Homeroom discussions at the start of each quarter would keep the pledge visible without making it punitive.
Conclusion
The problem of phone-driven sleep loss is real and measurable. A voluntary screens-down pledge supported by quarterly homeroom check-ins would address the social and timing dimensions of the problem without requiring a hardware ban or a policy fight. It is a small intervention with a clear connection to the problem it is trying to solve.
Both parts of problem in intro, solution refers to problem, conclusion returns to both
Introduction states both parts of the problem (sleep loss, late-night phones). Body includes a solution (screens-down pledge) that refers back to the problem. Conclusion states the problem and its solution. Matches Full Evidence on Organization for Grade 8 problem/solution.
Problem with detail, solution with detail, transition connects them
One problem with a relevant detail (nine hours needed, seven received). One solution with a relevant detail (voluntary pledge starting 9 p.m., quarterly homeroom). Transitional language (would shift, because) connects problem to solution. Matches Full Evidence.
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 throughout. Matches Full Evidence on Conventions for a Grade 8 response.
