Description
Compare supplied prior-learning evidence age with a validity window.
Adult-learning records distinguish self ratings, comparison criteria, acknowledgments, feedback states and recognized credits. Closing a feedback item can mean completion or decline, while a reported rating gap does not establish competence. Supplied priorities and evidence references need the broader learning context.
Compare supplied prior-learning evidence age with a validity window.
When to use this tool
Use Prior Learning Evidence Expiry when you already have evidenceDate, validForDays, assessmentDate and need to compare supplied prior-learning evidence age with a validity window.
How to use the tool and how it works
- Enter evidenceDate, validForDays, assessmentDate. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read ageDays, remainingDays, withinSuppliedWindow. Inspect withinSuppliedWindow before interpreting the associated values.
Parse real UTC dates, require assessment>=evidence and validForDays nonnegative safe whole; age=assessment-evidence, remaining=validFor-age, within=age<=validFor.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| evidenceDate | Evidence Date | Required. Text; maximum UTF-16 length 8192. Real proleptic Gregorian YYYY-MM-DD; four-digit years 0000-9999 accepted. |
| validForDays | Valid For Days | Required. Safe integer; minimum 0. |
| assessmentDate | Assessment Date | Required. Text; maximum UTF-16 length 8192. Real proleptic Gregorian YYYY-MM-DD; four-digit years 0000-9999 accepted. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| ageDays | Age Days | Required. Safe integer. |
| remainingDays | Remaining Days | Required. Safe integer. |
| withinSuppliedWindow | Evidence age<=validForDays, including equality; evidence from after assessment is rejected. | Required. Boolean. |

}Limitations and assumptions
- Equality is within the supplied window and expired evidence gives negative remaining days. No actual competence, evidence authenticity, qualification policy or legal validity is established.
- 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 goals, criteria, learner preferences, evidence and recognition policy. Use an appropriate educational assessment for learning decisions; local labels, time gaps and supplied credit balances do not establish outcomes or informed agreement.
