STEM PRACTICE AND EVIDENCE WORKBENCH
Calculate a laboratory-evidence rubric score and flag criterion awards that exceed disclosed evidence-level ceilings.
Review output
Load the worked example to inspect realistic inputs, or enter anonymous classroom or laboratory evidence. Results remain in this browser tab until you copy or download them.
Transparent method
Rubric percentage equals total awarded points divided by total possible points times one hundred. Present evidence can support the full criterion maximum, partial evidence can support at most 75 percent, and missing evidence supports zero under this local audit. The score threshold and evidence-consistency check are reported separately. A percentage at or above the entered threshold describes the supplied point total only. Criterion award supported means the award does not exceed the evidence-level ceiling; it does not prove that the descriptor was applied well. Inspect the actual evidence, feedback, moderation notes, access conditions, and approved policy before recording a grade.
Confirm the question, source, units, notation, response coding, model assumptions, and review threshold. Keep an unchanged copy of the original evidence.
Run the worked example, inspect every intermediate row, and compare it with a hand calculation, diagram, representation, or approved subject method.
Record the method, assumptions, units, classifications, and flagged rows. Verify the editable report independently before educational or laboratory use.
How to interpret the result
Use as a moderation aid when criterion points and evidence availability need a transparent cross-check. The workbench totals points and exposes awards that conflict with one disclosed ceiling rule. It does not grade the work, interpret a photograph or report, decide accommodations, infer authorship, or replace criterion descriptors and teacher judgment.
The fictional report earns four of four for variable definition, three of four for its data table, and two of four for a partial uncertainty discussion. The conclusion row awards two points while evidence is marked missing. Because missing evidence has a zero-point ceiling in this review rule, that award is flagged even though it remains in the entered total.

Do not average criterion percentages without weighting points, award evidence that is marked missing, treat partial as automatically half credit, change the approved rubric silently, use the readiness threshold as a universal pass mark, expose identifiable work, or let a total hide a critical criterion. Document evidence and any moderated override.
Learning boundary
This browser-local workbench applies only the disclosed rules. It cannot diagnose a learner, certify an experiment, or replace teacher, laboratory, and safety judgment.

Practical questions
No. Processing occurs in the current browser tab. Avoid personal information and retain authoritative records only in the approved school system.
No. It describes entered evidence under one disclosed rule. Review reasoning, uncertainty, access, and several evidence sources.
Treat it as an editable calculation aid. Show your own reasoning, cite required sources, and follow course and academic-integrity rules.
