Learner Available Slot Share Tool

Description

Eligible time includes accessible slots; available time requires both flags.

Adult-learning budgets allocate supplied time, observations, support hours and optional participation. Elapsed session time differs from assessor person-time or serial per-learner time. A completeness count or feasible time balance does not itself assess competence, accessibility or learning quality.

Eligible time includes accessible slots; available time requires both flags.

When to use this tool

Use Learner Available Slot Share when checking the stated adult-learning time, participation, resource or support-allocation convention.

How to use the tool and how it works

Enter slotDurations, available, accessible. Follow any array-alignment requirements below. Use the units and conventions below.
Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
Read eligibleDuration, availableDuration, share, defined. Inspect defined before interpreting the associated values.

Require aligned nonnegative slot durations and available/accessible flags. Eligible time includes accessible slots; available time requires both flags. Return available/eligible or zero with defined=false for no accessible duration.^[1]

Input field	Meaning and units	Accepted input
slotDurations	Slot Durations	Required. Array of finite number; minimum 0; maximum items 256.
available	Available	Required. Array of boolean; maximum items 256.
accessible	Accessible	Required. Array of boolean; maximum items 256.

Output field	Interpretation	Returned shape
eligibleDuration	Eligible Duration	Required. Finite number.
availableDuration	Available Duration	Required. Finite number.
share	Dimensionless share using the operation-specific denominator stated above; not a percentage number.	Required. Finite number.
defined	Whether the corresponding reporting denominator/value is defined; inspect before interpreting zero placeholders.	Required. Boolean.

Limitations and assumptions

Accessibility and availability are caller assertions; overlapping time slots are not merged or scheduled.
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 actual learner needs, activity plans and verified records with the responsible educational team for substantive scheduling and assessment decisions.
