State assessment proficiencies
Bellwork acquires public assessment data from state education agencies independently, normalizes the releases into one product schema, and exposes that schema across the dashboard, API, MCP transport, and AI result surfaces.
One customer-facing schema over fifty different reporting habits.
Bellwork collects public assessment releases from each state independently. States publish different files, terms, fields, grades, suppression rules, and update schedules, so acquisition is handled source-by-source rather than through one national feed.
State-specific releases are mapped into one Bellwork schema for districts, schools, subjects, grades, school years, proficiency counts or percentages, tested counts, state baselines, and data-quality flags.
The normalized records are projected into fast product tables for dashboard lists, entity panels, filters, map area summaries, API responses, MCP tools, and AI result cards.
Bellwork preserves quality and comparability context in the product surface. Suppressed, partial, unavailable, and unknown values are marked instead of being treated as zero.
The dashboard is a consumer of the same API-shaped projection used by MCP and AI tools. Product surfaces should not reach around the API to reinterpret raw state files.
The selected entity and subject have a usable current proficiency value.
The state release is present, but some expected grades, groups, or measures are missing.
The state withheld the value, commonly because the underlying student count is too small.
Bellwork does not have a current public value for that entity, subject, and year.
This is state-defined proficiency, not NAEP.
Each state defines its own assessments, grade coverage, cut scores, school-accountability rules, and suppression thresholds. A reported proficiency percentage is therefore most reliable as a within-state local context signal.
Bellwork keeps this source separate from NAEP-style data. State assessment proficiency is useful for district and school operating detail; NAEP is the cleaner source for national cross-state comparisons.
