STEM PRACTICE AND EVIDENCE WORKBENCH
Group prerequisite evidence by target and audit essential-skill thresholds, evidence-source variety, and consistent readiness claims.
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
For each row, percentage equals correct divided by attempted times 100. Group rows by target. Readiness requires at least one prerequisite marked essential, every essential prerequisite at or above the declared percentage threshold, and at least the declared number of unique normalized source labels. Every repeated target claim must agree with this combined result. Supported means the readiness label follows the entered threshold, essential designations, and source rule. It does not mean every learner is ready or that a prerequisite is instructionally necessary. Review item alignment, sample size, opportunity to learn, recency, independence, misconceptions, accommodations, language demands, confidence, and consequences with qualified educators before revising a pathway.
Confirm the learning question, authoritative source, units, notation, response coding, model assumptions, and review threshold. Keep an unchanged copy of the original evidence and remove learner names or identifiers.
Run the worked example first, inspect every intermediate row, and compare it with a hand calculation, diagram, representation, or approved subject method. Correct input evidence before interpreting a flag.
Record the method, assumptions, units, classifications, and flagged rows. Verify the editable report independently, connect the numerical signal with learner reasoning, and document any teaching or laboratory decision outside this tool.
How to interpret the result
Use before starting a STEM target or assigning support to check whether evidence exists for essential prerequisites across more than one source. The workbench separates score threshold from evidence diversity and exposes conflicting readiness labels. It does not diagnose an individual, infer causality, select an intervention, validate an assessment, predict success, or turn one recent score into permanent mastery.
Linear systems has equation-solving and ordered-pair evidence from quiz and interview sources. Both essential percentages reach 75 percent, so ready is supported. Projectile modeling has vector evidence above threshold but graph reading below it, so review is supported. Review source variety has strong results on both prerequisites but only one source type, making its ready claim unsupported.

Do not average away a failed essential prerequisite, count two forms of the same quiz as independent sources without justification, mark every skill essential, compare unequal tasks as equivalent, use tiny attempted counts without uncertainty, or treat a threshold as a diagnosis. Preserve row evidence, define the target and source rule, and inspect actual learner reasoning.
Learning boundary
This browser-local workbench applies only the disclosed rules. It cannot diagnose a learner, certify an experiment, establish assessment validity, or replace teacher, laboratory, curriculum, accessibility, 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.
