Description
Calculate a rubric score under a supplied optional-criterion policy.
Educational records need explicit score maxima, optional-criterion policy, timing allowances, choice positions and group capacities. Optional points and their maxima must use the same inclusion rule. Nominal seat counts and supplied extension fractions do not establish actual accessibility, attendance, appropriate support or assessment fairness.
Calculate a rubric score under a supplied optional-criterion policy.
When to use this tool
Use Rubric Optional Criterion Denominator Choice when you already have requiredMaximum, optionalMaximum, earnedRequired, earnedOptional, includeOptional and need to calculate a rubric score under a supplied optional-criterion policy.
How to use the tool and how it works
- Enter requiredMaximum, optionalMaximum, earnedRequired, earnedOptional, includeOptional. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read denominator, countedEarned, scoreFraction. Use the output convention below.
Require nonnegative maxima and earned values within their maxima; select required plus optional maximum and earned amount when includeOptional=true. Require finite positive denominator and return countedEarned/denominator.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| requiredMaximum | Required Maximum | Required. Finite number; minimum 0. |
| optionalMaximum | Optional Maximum | Required. Finite number; minimum 0. |
| earnedRequired | Earned Required | Required. Finite number; minimum 0. |
| earnedOptional | Earned Optional | Required. Finite number; minimum 0. |
| includeOptional | Include both optional earned points and optional maximum, or omit both. | Required. Boolean. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| denominator | Denominator | Required. Finite number. |
| countedEarned | Counted Earned | Required. Finite number. |
| scoreFraction | Score Fraction | Required. Finite number. |

}Limitations and assumptions
- Optional earned points and maxima are excluded together. No rubric, missing-score policy, fair comparison or grade is selected.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Review the complete rubric, course and accommodation policy, schedule and actual classroom arrangement for operational decisions. Work with the full records when scoring, grouping or access matters beyond one supplied count, tag comparison or time allowance.
