Up until this year Assessment Interpretation values sent to MSIX were treated in two different ways depending on whether they were state assessments or not. For non-state assessments, MSIX expected a value of either Passed or Failed, but you could pass any other value if you prefixed it with "Other". For state assessments, MSIX expected one of the values Advanced, Basic, Below Basic, Failed, Far Below Basic, Passed, or Proficient; there was no provision for sending values other than these. This required all states to provide mappings from the values they used within the state to these MSIX-approved values. This was often difficult or easy to forget, but if a mapping wasn't provided, there was simply no way to get MSIX to display the value that the state actually uses.
