What this rubric measures
The B.E.S.T Expository Writing Rubric, Grades 7–10 is the official scoring guide used to evaluate student writing on Florida B.E.S.T Writing assessments. It is an Holistic by domain 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 Florida Department of Education B.E.S.T Writing scoring guide.
1 Purpose/Structure
- Central idea is focused on the task and consistently maintained throughout.
- Organizational structure strengthens the response and allows for the advancement of the central idea.
- Purposeful transitional strategies connect ideas within and among paragraphs and create cohesion.
- Effective introduction and conclusion enhance the essay.
- Central idea is focused on the task and generally maintained throughout.
- Organizational structure is logical and allows for advancement of the central idea.
- Purposeful transitional strategies connect ideas within and among paragraphs.
- Sufficient introduction and conclusion contribute to a sense of completeness.
- Central idea may be unclear, loosely related or insufficiently sustained within the task.
- Organizational structure may be repetitive or inconsistent, disrupting the advancement of ideas.
- Transitions attempt to connect ideas but may lack purpose and/or variety.
- Introduction and conclusion may be present but repetitive, simplistic, or otherwise ineffective.
- Central idea may be absent, ambiguous, or confusing, demonstrating lack of awareness of task.
- Demonstrates little or no discernible organizational structure.
- Transitions may be absent or confusing.
- Introduction and conclusion may be unrelated to the response and/or create confusion.
- Too brief to demonstrate knowledge of purpose, structure, or task.
Scored holistically by domain. The response earns its score by demonstrating most of the descriptors in a given score point.
2 Development
- Skillful development demonstrates thorough understanding of the topic.
- Effective elaboration may include original student writing combined with (but may not be limited to) paraphrasing, text evidence, examples, definitions, narrative, and/or rhetorical techniques as appropriate to support the central idea.
- Smoothly integrated, relevant evidence from multiple sources lends credibility to the essay.
- Evidence is appropriately cited.
- Logical development demonstrates understanding of the topic.
- Adequate elaboration may include (but may not be limited to) a combination of original student writing with paraphrasing, text evidence, examples, definitions, narrative, and/or rhetorical techniques as appropriate to support the central idea.
- Relevant, integrated evidence from multiple sources lends credibility to the exposition.
- Evidence is appropriately cited.
- Development may demonstrate partial or incomplete understanding of the topic.
- Elaboration may attempt to develop the central idea but may rely heavily on the sources, provide loosely related information, be repetitive or otherwise ineffective.
- Evidence may be partially integrated and/or related to the topic but disconnected from the exposition.
- Lacks appropriate citations.
- Response may demonstrate lack of understanding of the topic and/or lack of development.
- Elaboration may consist of confusing ideas or demonstrate lack of knowledge of elaborative techniques.
- Evidence from sources may be absent, vague, and/or confusing.
- Lacks appropriate citations.
- Too brief to demonstrate knowledge of elaboration, topic, or sources.
Citation is not a holistic consideration. Without citation, the highest score possible in Development is a 2.
3 Language
- Integration of academic vocabulary strengthens and furthers ideas.
- Skillful use of varied sentence structure contributes to fluidity of ideas.
- Use of standard English grammar, punctuation, capitalization, and spelling demonstrates consistent command of the communication of ideas.
- Tone and/or voice strengthens the overall response.
- Integration of academic vocabulary demonstrates clear expression of ideas.
- Sentence structure is varied and demonstrates grade-appropriate language facility.
- Use of grammar, punctuation, capitalization, and spelling demonstrates grade-appropriate command of standard English conventions.
- Tone and/or voice is appropriate for the overall response.
- Vocabulary and word choice may be imprecise or basic, demonstrating partial command of expression of ideas.
- Sentence structure may be partially controlled, somewhat simplistic, or lacking grade-appropriate language facility.
- Inconsistent use of correct grammar, punctuation, capitalization, and/or spelling may contain multiple distracting errors, demonstrating partial command of standard English conventions.
- Tone and/or voice may be inconsistent.
- May be grammatically accurate but too brief to demonstrate grade-appropriate command of language skills.
- Vocabulary and word choice may be vague, unclear, or confusing.
- Sentence structure may be simplistic or confusing.
- Use of grammar, punctuation, capitalization, and/or spelling may contain a density and variety of severe errors, demonstrating lack of command of standard English conventions, often obscuring meaning.
- Tone and/or voice may be inappropriate.
- Brevity with errors demonstrates lack of command of language skills.
Scored holistically by domain. Brevity with errors demonstrates lack of command of language skills and caps the Language score regardless of the strength of the other domains.
How to score with the B.E.S.T Expository Writing Rubric, Grades 7–10.
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.
Holistic by domain, scored independently
- Score each of the three domains on its own pass, then combine. Total possible is 12 (4 + 4 + 4).
- Within a domain, do not score each bullet independently. Identify the score point whose set of descriptors the response best demonstrates most of.
- The three domains are scored independently. A response can earn 4 on Purpose/Structure and 2 on Development.
Transitions are "purposeful" at 7–10
- The 7-10 rubric uses 'purposeful transitional strategies' where the 4-6 rubric uses 'varied transitional strategies.' This is a meaningful shift.
- At 7-10, transitions are evaluated on whether they CREATE COHESION between ideas, not just on their presence and variety.
- A response with many transitions that do not serve the central idea may score 2 even if the transitions are varied.
The citation rule still applies
- Citation is not a holistic consideration. Without citation, the highest score possible in Development is a 2.
- A 7-10 expository response with strong elaboration and varied evidence still caps at 2 on Development if the writer never cites the sources.
- This rule applies only to Development. Purpose/Structure and Language are unaffected by the citation rule.
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 domain where graders are more than one point apart.
- Re-norm halfway through a long batch. Drift is real.
Notes for the B.E.S.T Expository Rubric, Grades 7–10
The B.E.S.T Expository rubric for Grades 7-10 follows the same three-domain structure as the 4-6 version but tightens the transitions descriptor. 'Varied' becomes 'purposeful' across all four score points in Purpose/Structure.
Expository writing on B.E.S.T centers on a 'central idea' rather than a 'position' or 'claim.' Counterclaims are not part of the Expository rubric, only the Argumentation rubric requires them.
Rhetorical techniques are explicitly listed as an elaboration option starting at this band (no footnote restricting them to a single grade). The expectation is that 9th and 10th graders can use rhetorical techniques to strengthen expository writing.
The citation rule still applies, without citation of source evidence, Development caps at 2 regardless of the quality of the elaboration.

What makes octopuses such effective hunters
For most people, the word "predator" brings sharks or lions to mind, but the octopus deserves a place on that list. Octopuses are effective predators because they combine extraordinary camouflage with problem-solving intelligence, a pairing that few other ocean animals can match. Together, those two abilities let octopuses hunt in environments where stronger or faster predators routinely fail.
Camouflage as a hunting tool
The first half of an octopus's hunting toolkit is its skin. Source 1 describes how "specialized cells called chromatophores expand and contract within milliseconds, allowing the octopus to match the color, brightness, and texture of nearby coral or sand" (Source 1). This is not passive blending. The article explains that octopuses actively choose backgrounds that will give them the best disguise before they wait for prey to approach. A crab the octopus is hunting often does not see the predator at all until the strike begins.
Intelligence in the hunt
The second half of the toolkit is harder to see but just as important. Source 2 explains that "researchers in Italy gave wild-caught octopuses a sealed jar containing a live crab, and within three minutes most octopuses had unscrewed the lid to reach the food" (Source 2). That kind of trial-and-error problem-solving is rare in invertebrates. In the wild, the same ability lets octopuses pry open clamshells, force their bodies through impossibly small cracks to chase prey, and remember which hunting spots have worked before.
Why the combination matters
Other ocean animals have camouflage. Other ocean animals show signs of intelligence. The reason octopuses stand out as predators is that they pair both abilities in the same animal. A reef fish can hide but cannot open a clam. A dolphin can solve problems but cannot disappear into the sand. Octopuses do both, sometimes within the same hunt.
Conclusion
Octopuses succeed as predators because they bring two distinct advantages to every hunt, near-perfect disguise and flexible intelligence. The combination is what makes them so effective.
Focused central idea, purposeful transitions
Central idea is clearly focused and generally maintained. The "two-part toolkit" framing creates a logical structure. Transitions like "The first half" are purposeful. A 4 would need an introduction and conclusion that more effectively enhance the essay, not just frame it.
Cited evidence from both sources, adequate elaboration
Both sources cited with integrated quotes. Each quote is followed by student elaboration that connects evidence to the central idea (chromatophores, jar experiment). Earns 3. A 4 would need more varied elaborative techniques, perhaps a definition of "invertebrate" or an analogy.
Grade-appropriate language with academic vocabulary
Academic vocabulary ("chromatophores," "invertebrates") is integrated. Sentence structure varies and conventions are clean. Voice is appropriate to the response. A 4 would need voice to strengthen the response (more authorial presence) and more skillful sentence variety.
