How to Score Writing Using the Florida B.E.S.T rubric
Florida's B.E.S.T (FAST) writing rubric uses a 4-point holistic scoring system across three domains. Teachers score each domain separately, with responses earning scores by demonstrating most descriptors in a given score point.
Scoring domains:
- Purpose/Structure: Organization, central idea/claim development, transitions, introduction/conclusion effectiveness
- Development: Evidence use, elaboration techniques, topic understanding, source integration and citation
- Language: Vocabulary precision, sentence variety, grammar conventions, tone appropriateness

Frequently Asked Questions About Florida B.E.S.T Writing Rubric
Common questions teachers ask about the FL B.E.S.T rubric. Contact us if you don't see your question answered below.
Teachers often use "FAST writing rubric," but Florida's official writing assessment is called "B.E.S.T. Writing." There is no separate "FAST Writing" test - FAST refers only to Reading and Mathematics assessments.
Students can revise their work within the testing session, but once they submit their response, no further changes are allowed. The computer-based format includes basic editing tools like spell-check, but students should be taught to budget time for reviewing and revising before submission.
Students have up to 120 minutes to complete their writing response, including reading the source texts, planning, drafting, and revising. However, most students finish within 90 minutes. Teachers should practice timed writing sessions to help students manage their time effectively.
Students receive 2-3 source texts that may include articles, infographics, charts, or excerpts from longer works. All sources relate to the writing prompt topic, and students must cite evidence from these sources to earn full Development domain points.
Focus on explicit instruction in the three domains: teach organizational patterns and transitions (Purpose/Structure), practice integrating textual evidence with proper citations (Development), and emphasize academic vocabulary and sentence variety (Language). Regular practice with timed writing using similar prompts is essential.
