Basis matching
A benchmark from another period or population may not be comparable.

Make the direction and size of a score gap explicit before deciding whether to review, maintain, or escalate support.
ASSIGNMENT WEIGHT BENCHMARK
Compare a score with a benchmark without losing the gap direction
The calculator reports signed distance, absolute distance, and a review-band state. It does not invent a benchmark or call it a universal standard.

HOW TO USE
Document the comparison
- Confirm the score and benchmark share the same grading basis.
- Enter the source benchmark and record its owner and date.
- Choose a review band that belongs to the local decision rule.
- Read signed gap before absolute gap.
- Use the state to decide whether evidence review is warranted.
SUBJECT FUNDAMENTALS
Benchmark concepts
- Benchmark
- Declared comparison value.
- Signed gap
- Score minus benchmark.
- Absolute gap
- Distance without direction.
- Review band
- Local distance within which review is triggered.
- Near state
- Absolute gap within the band.
- Basis
- Population, period, and scoring definition.
CALCULATION METHOD
Subtract first, classify second
G = S − BA = |G|Near when A ≤ band
Defaults: G=84−80=4 points; A=4; with a 3-point band the state is above benchmark, outside band.
DEEPER ANALYSIS
Interpretation boundaries
Band ownership
The band is a local policy parameter, not a universal statistical interval.
Rounding risk
Classify on unrounded values so a display tie does not change the state.
DETAILED CALCULATION PROCESS
Ten auditable steps
- Formula G=S−B.
- Signed subtraction preserves direction.
- S,B are percentages; G,A,band are points.
- Defaults are 84,80,3.
- No unit conversion is needed.
- G=84−80=4.
- A=|4|=4.
- 4 is greater than the 3-point band.
- Status is above benchmark.
- Reverse check: 80+4=84.
RESULT INTERPRETATION
State what the gap can and cannot say
Above or below is descriptive. It does not establish why the gap exists or whether the benchmark is fair.
WORKED DECISION CASES
Two review choices
Small gap, inside band
Review the evidence and measurement noise before changing a study plan.
Large negative gap
Check category weights, denominator, and support needs before interpreting the score as ability.
EVIDENCE AND DATA LINEAGE
Record the comparator
Retain benchmark source, period, population, score basis, band owner, and calculation date.
LIMITS AND EXCLUSIONS
No causal diagnosis
- No claim of rank, ability, fairness, or cause.
- No automatic confidence interval or sample-size adjustment.
- No replacement for official policy.
- No hidden conversion between grading bases.
TECHNICAL GLOSSARY
Benchmark terms
- Comparator
- Value used as the reference.
- Signed difference
- Difference retaining direction.
- Absolute difference
- Magnitude without direction.
- Review band
- Declared action zone.
- Basis
- Definition behind the values.
- Boundary
- Threshold where classification changes.

IMPORTANT NOTE
Validate the comparator
A precise gap to an unsuitable benchmark is still an unsuitable decision.
FREQUENTLY ASKED QUESTIONS
Benchmark questions
What does near benchmark mean?
The absolute gap is within the entered review band.
Can the benchmark be zero?
Yes, although the decision still depends on the declared meaning of zero.
Why show signed and absolute gaps?
Signed gap shows direction; absolute gap shows distance.
Is the benchmark an official standard?
Only if the source owner says so; otherwise it is a planning reference.
