How to retrieve the final assessment score through the API
Syntax
- https://assessmentcenter.net/ac_api/2014-01/Results/{AssessmentOID} - returns the specified form as an html page
- https://assessmentcenter.net/ac_api/2014-01/Results/{AssessmentOID}.xml - returns the specified form in xml format
- https://assessmentcenter.net/ac_api/2014-01/Results/{AssessmentOID}.json - returns the specified form in json format
Remarks
AssessmentOID is the key returned from a call to the https://assessmentcenter.net/ac_api/2014-01/Assessments/{FormOID} API.
The last item administered (i.e. 'position' attribute) is the final score for the assessment.
T-Score = Theta * 10 + 50.0
Standard Error = StdError * 10
If no results are found for the AssessmentOID, the following response will return:
- JSON - {"Error":"No data found.", "UID":"","Name":"", "Items":[]}
- XML - <Form Error="No data found." UID="" Name=""></Form>
