STEM REASONING AND EVIDENCE WORKBENCH
Compare anonymous objective-level opportunity counts and successful retrieval rates with teacher-defined coverage rules.

Transparent method
Success percentage equals successful retrieval responses divided by completed opportunities times one hundred. An objective is ready under the entered planning rule only when opportunities are at least the minimum and success percentage is at least the minimum. The engine applies both conditions independently and does not average sparse rows into larger objectives. A supported status means the teacher claim matches the entered dual-threshold rule. It does not establish learner mastery or instructional effectiveness. Review actual explanations, prompt alignment, access conditions, response independence, feedback, spacing, sample size, and recent evidence before deciding what practice or teaching should happen next.
Confirm the question, approved source, units, notation, signs, response coding, model assumptions, and review threshold. Keep an unchanged copy of measurements or learner evidence.
Run the worked example, inspect every intermediate row, and compare the result with a hand calculation, diagram, representation, periodic table, or approved laboratory method.
Record the method, assumptions, uncertainty, units, classifications, and flagged rows. Verify the editable report independently before instruction, assessment, or laboratory use.
How to interpret the result
Use while reviewing a unit plan, quiz sequence, or practice schedule to find objectives with too few completed retrieval attempts or weak observed success under a teacher-selected rule. It describes coverage evidence rather than mastery. It does not measure spacing, feedback quality, independence, confidence, accessibility, transfer, long-term retention, or intervention eligibility.
Four attempts with three successes gives 75 percent and meets both the three-opportunity and 70-percent rules. Three with two is about 66.7 percent and remains under review. Five with four meets both. Two successful attempts out of two look perfect, but the evidence count is below three, so the entered ready claim is flagged.

Do not count rereading as retrieval without a response, divide by enrollment instead of completed opportunities, treat one perfect response as stable evidence, hide unsuccessful attempts, combine unlike objectives, expose individual histories, or use a threshold as a diagnosis. Define the evidence event, protect privacy, and pair counts with qualitative reasoning.
Learning boundary
This browser-local workbench applies only the disclosed rules. It cannot diagnose a learner, certify an experiment, establish a chemical structure, 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 school-approved system.
No. It describes entered evidence under one disclosed rule. Compare several evidence sources and ask for reasoning before drawing a conclusion.
Treat it as an editable calculation aid. Show your own reasoning, cite required sources, and follow the course method and academic-integrity rules.
