An assessment concept defining how evidence of learning is collected, interpreted, and used for decisions. It governs measurement design, scoring, feedback, and reporting used to evaluate progress and attainment. It does not provide fair conclusions without alignment to objectives, consistent scoring, and attention to measurement error. It supports improvement and accountability by making performance observable and trackable over time. The concept is generally stable, though tools and standards for measurement evolve over time.

Principle

Use explicit, measurable criteria and graduated scoring to make assessments transparent, comparable, and tied to user-centered objectives rather than relying on informal judgment.

Demonstration

A school district rubric rates a communication device on accessibility (1–4), ease of customization (1–4), durability (1–4), data portability (1–4) and staff training requirements (1–4); the summed profile guides procurement and individualized supports.

Misapplication

Treating the rubric as a compliance checkbox or an absolute oracle—e.g., eliminating devices that score moderately without considering learner preference, context, or qualitative input.

Consequence

When used correctly the rubric produces consistent evaluations that inform transparent decisions, enable comparisons across options and document rationale for selection or modification of AT.

Reversal

An unstructured, purely narrative judgment process where devices are chosen by anecdote or vendor influence without explicit criteria or documented scoring.

Boundary

Applies to evaluation and decision-support; it is not a clinical diagnostic instrument, a substitute for individualized clinical assessment, nor a technical specification for device manufacture.

Semantic Tension

Tension exists between the rubric as a formative, developmental tool (to guide improvement) and as a summative compliance instrument (to justify procurement or audit), which can change how criteria are weighted.

Synthesis

A rubric for assistive technology is a documented set of criteria and levels that translates user goals and technical requirements into comparable scores, enabling transparent, repeatable AT evaluation and decision-making.
