In order to add students to Educator Portal, a State_Student_Identifier needs to be provided. In New York, this is the NYSSIS ID.
For students attending a public school or BOCES, you need to contact the district data coordinator of the school the student is attending.
For students attending a charter school, you need to contact the school data coordinator.
For students attending nonpublic schools, you need to contact the school data coordinator at your nonpublic school or the district data coordinator of the public district that has Committee on Special Education (CSE) responsibility. A process for obtaining NYSSIS IDs for nonpublic schools is available here.
More information on the NYSSIS system and state student ids can be found here.
