Scale Score Mapping Resources

Within Surpass users can create test forms with scale scores attached. In Test creation users can upload a CSV which maps the raw score of marks available for a test to a new scale score mark, when this is delivered to the candidate and they receive their results they can be provided the scale score rather than the raw score for the test. A reason for this may be for an organisation to scale and standardise tests based  that some tests do not have difficult items in the test so have to be scaled down from more advanced papers. We also allow users to edit scale score mappings in reporting therefore potentially changing the scale score a candidate has achieved. 

As part of the Result, AnalyticsResult and HistoricalResult API resources the response informs the consumer of the scale score achieved by the candidate (if it has been applied) and a URL to the full scale score mapping that was applied to the result. Within the Surpass API we have the concept of two separate resources, scale score mapping and analytics scale score mapping. Both resources provide the same purpose but query different Surpass databases, AnalyticsScaleScoreMapping relates to the scale score provided in the AnalyticsResult and HistorcialResult resources and ScaleScoreMapping relates to the Result resource.
