Description
Link a supplied common item across explicit test-form identifiers.
Assessment records distinguish presented items, responses, deliberate skips, missingness, accommodations, versions and reference populations. A score contribution depends on its chosen denominator and weight, while one confidence gap is not a full calibration study. Recorded observations and timing differences do not establish learner ability or an appropriate intervention.
Link a supplied common item across explicit test-form identifiers.
When to use this tool
Use Test Form Link Item Identifier when you already have firstFormId, secondFormId, commonItemId and need to link a supplied common item across explicit test-form identifiers.
How to use the tool and how it works
- Enter firstFormId, secondFormId, commonItemId. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read token. Use the output convention below.
Enter firstFormId, secondFormId, commonItemId using the field constraints below. Encode these values, in exactly that order, as a JSON array and return the serialized array as text in token. String values are preserved without trimming or external terminology lookup.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| firstFormId | First Form Id | Required. Text; minimum UTF-16 length 1; maximum UTF-16 length 8192. |
| secondFormId | Second Form Id | Required. Text; minimum UTF-16 length 1; maximum UTF-16 length 8192. |
| commonItemId | Common Item Id | Required. Text; minimum UTF-16 length 1; maximum UTF-16 length 8192. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| token | Token | Required. Text; maximum UTF-16 length 8192. |
{
"input": {
"firstFormId": "F17",
"secondFormId": "F18",
"commonItemId": "I4"
},
"output": {
"token": "[\"F17\",\"F18\",\"I4\"]"
}
}Limitations and assumptions
- The result records supplied values without estimating equating parameters. Sources and asserted relationships are not independently authenticated.
- 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.
Alternative or Complementary methods
Use the full assessment manual, item records, population reference and research design for score interpretation. Review missingness, exposure, accommodations and comparability; local labels or contributions do not replace psychometric analysis or an appropriate educational assessment.
