Which approach best describes how to assess writing development in PK–3?

• A. Observing students during independent reading only
• B. Timed running records
• C. Oral reading fluency tests
• D. Writing portfolios, step-by-step writing prompts, and rubrics evaluating ideas, organization, and conventions

Answer: (D)

Assessing writing development in PK–3 means gathering ongoing evidence of how students plan, draft, revise, and express ideas over time. The strongest approach uses a combination of writing portfolios, step-by-step writing prompts, and rubrics that evaluate ideas, organization, and conventions. Portfolios give a trail of growth, showing how a student’s writing changes across weeks or months and across different genres. Step-by-step prompts reveal the writing process—how students brainstorm, outline, draft, and revise—so you can see where they’re making progress and where they need support. Rubrics provide clear criteria for evaluating the quality of ideas, the structure of the writing, and the correctness of conventions, giving consistent feedback and a way to measure improvement over time.

Observing only during independent reading captures reading behaviors, not writing development. Timed running records focus on decoding rate and accuracy, not how a child composes text. Oral reading fluency tests assess how smoothly a student reads aloud, which again does not measure writing growth. So while those assessments are valuable for reading skills, they don’t provide the comprehensive picture of writing development that portfolios, prompts, and rubrics offer.
