STEM REASONING AND EVIDENCE WORKBENCH
Allocate an exact assessment point total across demand bands with largest-remainder rounding and visible task minimums.

Transparent method
Raw band points equal total points times target percentage divided by 100. Take the floor of each raw value, then subtract their sum from the exact total. Sort fractional remainders from largest to smallest, preserving input order for ties, and add one point to that many bands. The resulting integer allocations sum exactly to the declared total. The report is an arithmetic blueprint, not evidence that task demand has been classified well. A one-point rounding adjustment is visible and reproducible. Review the actual reasoning path, scaffolds, response mode, prerequisite load, point weight, task count, estimated time, standard coverage, scoring criteria, choice, and accessibility before approving the assessment plan.
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 after a team has chosen defensible cognitive-demand categories and target shares for a quiz, assessment, or task set. The workbench converts percentages into exact whole points without losing the total. It does not classify questions from verbs, write items, validate a framework, measure difficulty, predict reliability, guarantee curriculum coverage, set grades, or determine whether a plan is fair.
A 100-point plan with shares 20, 35, 30, and 15 allocates exactly those point totals across four demand bands. Minimum task counts three, four, three, and one expose average points per minimum task. With a total that creates fractions, whole points are floored and remaining points go to the largest decimal remainders in stable entered order.
Raw band points equal total points times target percentage divided by 100. Take the floor of each raw value, then subtract their sum from the exact total. Sort fractional remainders from largest to smallest, preserving input order for ties, and add one point to that many bands. The resulting integer allocations sum exactly to the declared total.

Review the actual reasoning path, scaffolds, response mode, prerequisite load, point weight, task count, estimated time, standard coverage, scoring criteria, choice, and accessibility before approving the assessment plan.
Do not classify demand from a verb alone, equate more points with deeper thinking, force rounded bands to total 99 or 101, hide the tie rule, use percentages that do not total 100, let one large item dominate a band unintentionally, or ignore accessible pathways. Review every task, document borderline classifications, and recalculate after content changes.

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.
