Which assessment is based on a representative sampling of student work that demonstrates growth over time?

• A. Informal reading inventory
• B. Portfolio-based assessment
• C. IRI
• D. Phonemic awareness assessment

Answer: (B)

This is about an assessment that shows how a student’s learning develops over time by collecting representative samples of their work. A portfolio-based approach gathers multiple pieces across learning periods—drafts, final products, assignments, rubrics, and reflections—to illustrate growth, mastery, and the strategies a student uses. Because it draws from a range of tasks and time points, it reveals trends and progress rather than a single snapshot of ability.

Informal reading inventories and reading inventories primarily provide a point-in-time or short-interval measure of reading level and behavior, not a curated series of work that demonstrates ongoing development. Phonemic awareness assessments focus on specific early literacy skills and are typically used for screening or diagnostic purposes rather than showing long-term growth through a representative collection of student work.
