What this rubric measures
The MAP EOC English I/II Source-Based Blended Writing Rubric is the official scoring guide used to evaluate student writing on Missouri MAP 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

1 Organization and Flow
The writing uses a clear and effective organizational structure, creating a sense of unity and completeness. The response is fully sustained and consistently and purposefully focused. The writing smoothly and effectively blends at least two genres (argumentative, expository, and/or narrative); blending is well thought out and purposeful:
- Controlling or main idea of a topic is clearly communicated, and the focus is strongly maintained for the purpose, audience, and task
- Consistent use of a variety of transitional strategies to clarify the relationships between and among ideas
- Effective introduction and conclusion
- Logical progression of ideas from beginning to end; strong connections between and among ideas with some syntactic variety
The writing uses an evident organizational structure and a sense of completeness though there may be minor flaws and some ideas may be loosely connected. The response is adequately sustained and generally focused. The writing adequately blends at least two genres (argumentative, expository, and/or narrative); blending is generally purposeful:
- Controlling or main idea of a topic is clear, and the focus is mostly maintained for the purpose, audience, and task
- Adequate use of transitional strategies with some variety to clarify the relationships between and among ideas
- Adequate introduction and conclusion
- Adequate progression of ideas from beginning to end; adequate connections between and among ideas
The writing uses an inconsistent organizational structure, and flaws are evident. The response is somewhat sustained and may have a drift in focus. The writing attempts to blend at least two genres (argumentative, expository, and/or narrative); blending seems forced and may distract from content:
- Controlling or main idea of a topic may be somewhat unclear, or the focus may be insufficiently sustained for the purpose, audience, and task
- Inconsistent use of transitional strategies and/or little variety
- Introduction or conclusion, if present, may be weak
- Uneven progression of ideas from beginning to end and/or formulaic; inconsistent or unclear connections between and among ideas
The writing uses little or no discernible organizational structure. The response may be related to the topic but may provide little or no focus. The writing shows little or no evidence of blending genres (argumentative, expository, and/or narrative):
- Controlling or main idea may be confusing or ambiguous; response may be too brief or the focus may drift from the purpose, audience, or task
- Few or no transitional strategies are evident
- Introduction and/or conclusion may be missing
- Frequent extraneous ideas may be evident
- Ideas may be randomly ordered or have an unclear progression
Organization and Flow is scored 1 to 4. The EOC rubric evaluates both organizational structure and blending of at least two genres (argumentative, expository, and/or narrative) within the same response.
2 Content Development/Elaboration
The writing provides thorough and convincing support/evidence for the controlling idea and supporting idea(s) that includes the effective use of facts and details. Comprehensive support is integrated, relevant, and specific. The response clearly and effectively expresses ideas, using precise language and vocabulary that is clearly appropriate for audience and purpose. Sensory, concrete, and figurative language is effectively used and clearly advances the purpose. The writing effectively appeals to the audience. The writing makes effective use of available resources; effectively uses relevant and sufficient text support from the resources with accuracy; correctly cites sources (either formally or informally):
The writing provides adequate support/evidence for the controlling idea and supporting idea(s) that includes reasoned analysis and the use of facts and details. Adequate support is integrated and relevant, yet may be general. The response adequately expresses ideas, employing a mix of precise with more general language and vocabulary that is generally appropriate for audience and purpose. Sensory, concrete, and figurative language is adequately used and generally advances the purpose. The writing adequately appeals to the audience. The writing makes adequate use of available resources; uses relevant and sufficient text support from the resources with accuracy; mostly correct in citing sources (either formally or informally):
The writing provides uneven, cursory support/evidence for the controlling idea and supporting idea(s) that includes some reasoned analysis and partial or uneven use of facts and details. Support may be weakly integrated, imprecise, repetitive, vague, and/or copied. The response expresses ideas unevenly, using simplistic language and vocabulary that is somewhat ineffective for audience and purpose. Sensory, concrete, and figurative language is weak and may not advance the purpose. The writing attempts to appeal to the audience. The writing makes limited use of available resources; inconsistently uses relevant and sufficient text support from the resources with accuracy; attempts to cite sources (either formally or informally):
The writing provides minimal support/evidence for the controlling idea and supporting idea(s) that includes little or no use of facts and details. Support is minimal, irrelevant, absent, incorrectly used, or predominantly copied. The response's expression of ideas is vague, lacks clarity, or is confusing. Vocabulary is limited or ineffective for audience and purpose. Sensory, concrete, and figurative language is used little or not at all; language does not advance and may interfere with purpose. The writing lacks awareness of the audience. The writing makes inadequate use of available resources; fails to use relevant and sufficient text support from the resources with accuracy; does not cite sources:
Content Development/Elaboration is scored 1 to 4. The EOC rubric evaluates content development, expression of ideas, audience appeal, AND use of resources including correct citation of sources (either formally or informally).
3 Conventions
The writing demonstrates an adequate command of conventions:
- Adequate use of correct sentence construction, punctuation, capitalization, usage, and spelling
The writing demonstrates a partial command of conventions:
- Limited use of correct sentence construction, punctuation, capitalization, usage, and spelling
The writing demonstrates little or no command of conventions:
- Infrequent use of correct sentence construction, punctuation, capitalization, usage, and spelling
Conventions is scored 0 to 2 holistically across variety (range of error types: sentence construction, punctuation, capitalization, usage, and spelling), severity (basic errors are more heavily weighted than higher-level errors), and density (proportion of errors to amount of writing done well, including the ratio of errors to length of the piece).
How to score with the MAP EOC English I/II Source-Based Blended Writing Rubric.
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-trait analytic, scored independently
- Score Organization and Flow (1 to 4) first, then Content Development/Elaboration (1 to 4), then Conventions (0 to 2). Sum for the rubric total out of 10.
- The EOC rubric is structurally similar to the grade-level MAP rubrics but evaluates two unique elements: blending of genres and explicit citation of sources.
- All three traits are independent. A response can score high on Organization but low on Development, or vice versa.
Blending of genres is a required EOC criterion
- EOC English I/II responses must blend at least two genres (argumentative, expository, and/or narrative) within the same response.
- A 4 requires blending that is well thought out and purposeful. A 3 requires blending that is generally purposeful. A 2 indicates blending that seems forced or distracts from content. A 1 indicates little or no evidence of blending.
- A single-genre response, no matter how strong, caps Organization and Flow at 1 because it does not satisfy the blending criterion.
Citation of sources is required at the EOC level
- The EOC Content Development trait explicitly evaluates citation of sources, either formally (with attribution) or informally (using phrases like according to the article).
- A 4 requires correct citation. A 3 requires mostly correct citation. A 2 indicates attempted citation. A 1 indicates no citation at all.
- Citation does not have to be MLA or APA. Informal attribution is acceptable at every score point, but the response must signal where its information came from.
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 MAP EOC English I/II Source-Based Blended Writing Rubric
The Missouri EOC English I and II assessments use a single rubric for the source-based blended writing task. The rubric language is identical for English I and English II; the difference is the complexity of the source material and the maturity expected in the writing.
Blending of at least two genres (argumentative, expository, and/or narrative) is a distinguishing feature of the EOC rubric. Students might write an argument that includes a narrative anecdote, or an explanation that incorporates an argumentative claim. The blending must be purposeful, not forced.
Citation of sources is explicitly required, either formally or informally. Many students write strong content but lose Content Development points by failing to attribute evidence to its source. Train students to use simple attributions like the article states, the author explains, or the report shows.
Conventions on the EOC rubric uses sentence construction (not sentence formation) to match the high school target. The 0-2 scale and holistic scoring approach are identical to the grade-level MAP rubrics.

The phone in our pocket: what social media is doing to teen brains
The average American teenager spends nearly five hours a day on social media, according to the Pew Research report referenced in Source 1. That number alone tells a story, but it does not explain why mental health professionals have grown so alarmed, or what we should actually do about it. The evidence from these three sources points in one direction: schools and families need to take coordinated action, because the platforms will not regulate themselves.
What the research actually shows
Source 2, a peer-reviewed study from the Journal of Adolescent Health, found that teens who spend more than three hours a day on social media are twice as likely to report symptoms of anxiety and depression compared to teens who spend less than one hour. The study controlled for socioeconomic status, family structure, and prior mental health history, so the correlation is not easily explained away. The authors are careful to say correlation is not causation, but they note the dose-response pattern is striking.
A story behind the numbers
I have seen this play out in my own school. Last year, a friend of mine deleted Instagram for a month as an experiment. She told me she had not realized how often she was checking it, how often she felt worse afterward, and how much mental space it had been occupying. Her grades went up that month, and she said she slept better. One anecdote is not science, but it matched what Source 2 described almost exactly.
Why the platforms will not fix this
Source 3, an interview with a former design engineer at a major social media company, explains why the platforms are unlikely to solve this on their own. "Engagement is the metric we optimized for," the engineer said. "Time on platform is what we got rewarded for. Mental health was not on the dashboard." When the business model depends on attention, any feature that reduces use is a threat to revenue.
What schools and families should do
Given that the platforms will not self-regulate, the responsibility falls to schools and families. Schools can establish phone-free classrooms, as some districts already have. Families can negotiate clear boundaries around bedtime and meal times. Neither of these is a complete solution, but Source 2 found that even reducing daily use from five hours to two cut anxiety symptoms by nearly a third. The intervention does not have to be perfect to make a real difference.
Conclusion
Social media is not going away, and demonizing it accomplishes nothing. But the evidence from all three sources is consistent: heavy use is hurting teen mental health, the platforms will not act on their own, and modest reductions in use produce measurable improvements. Schools and families have to step into the gap.
Effective structure, purposeful genre blending
Clear introduction that frames stakes and previews the argument. Each section advances a sub-argument. Genre blending is purposeful, argument (position on what to do), exposition (research findings), and narrative (the friend's Instagram experiment).
Comprehensive sources, correctly cited, audience-aware
Evidence from all three sources is integrated, specific, and explained. Each source is cited informally but consistently (Source 1, Source 2, the engineer in Source 3). Vocabulary is precise and audience-aware.
Adequate command of conventions
Sentence construction, punctuation including quotation handling, capitalization, usage, and spelling are correct throughout. There are no patterns of errors. Earns full credit on the MAP EOC 0-2 Conventions sub-scale, which is the maximum possible on this trait.
