Report state enrollment data to the Ed-Fi ODS using the StudentSchoolAssociation resource with correct entry type and exit descriptors

Steps

1. Obtain the SEA's full descriptor list for entryType (e.g., 'Next year school', 'Re-entry', 'Transfer from public school') and exitWithdrawType descriptors by GET to /ed-fi/entryTypeDescriptors and /ed-fi/exitWithdrawTypeDescriptors.
2. Map your SIS enrollment codes to the SEA's descriptor URIs; document the mapping in a configuration file rather than hardcoding URIs.
3. POST to /ed-fi/studentSchoolAssociations with the required fields: studentReference (studentUniqueId), schoolReference (schoolId), entryDate, entryGradeLevelDescriptor, and entryTypeDescriptor.
4. When a student withdraws, PATCH or PUT the existing association record to add exitWithdrawDate and exitWithdrawTypeDescriptor; do not delete the record as SEAs require audit history.
5. For state reporting of membership days, also submit StudentEducationOrganizationResponsibilityAssociation records when the enrolling school differs from the serving school.
6. Validate completeness: the SEA's compliance dashboard will flag records missing required state-specific extension fields (e.g., tuition payer code); resolve these before the state reporting window closes.
