The StaffStudentGrowthMeasure extension in the model can only load data that is unique by teacher-year. However, our data files contain multiple scores per teacher-year, for those teachers that instruct multiple grade levels, or multiple subject. For example, a 4th/5th grade math teacher that has a score for grade 4 math, grade 5 math, and overall scores for both grades can only have a single record loaded for a given year. Similarly, a 4^th^ grade self-contained teacher that has a score for grade 4 math and grade 4 ELA can only have a single record loaded for a given year. We’d like to request that the StaffStudentGrowthMeasure field allow multiple records per teacher-year, varying by grade and/or subject.
