(1) Vendor needs to provide cloud–based centralized rostering and user access management solution.– Implement a middleware and aggregator platform to serve as a central data hub, securely connecting the district's authoritative student information system (SIS) data to all downstream educational technology (EdTech) applications.– System must automatically create user accounts in all connected applications when a new user record appears in the authoritative SIS data. – Platform must automatically detect and propagate changes from the SIS data to all downstream applications.– Platform must aggregate core rostering data from the SIS data and map it to a standardized format.– Solution must be capable of consuming and producing rostering data in both RESTful API (using JSON) and the formatted CSV file within a ZIP archive.– System must define and manage roles for students, teachers, administrators, and staff, automatically assigning entitlements based on these roles.– Solution must understand and support a multi–level organizational structure (e.g., a teacher is a user, has a role, teaches at a specific school, for a specific course/class) to correctly manage access permissions.– Platform must then be able to map this standardized data to the specific requirements and attributes of each downstream application.– Platform must support fine–grained access profiles to enforce the principle of least privilege, ensuring that users only receive the specific access required for their job function.(2) All questions must be submitted no later than November 7,2025.
