The grtschl_id field in the school_point_primary_attributes_usa table will have null values in the September 2024 (2024.09) release. GreatSchools data will need to be linked using the NCES ID. The grtschl_id field will be removed from the product in the December 2024 (2024.12) release.
A new alternate ID table named school_point_altids_usa will be added in the 2024.09 release, to provide additional linkage across product layers and support additional use cases.
This table will have the following structure:
| Field Name | Data Type | Data Length | Description |
| ALTID_ID | INTEGER | - | Primary key |
| OBJ_ID_PNT | INTEGER | - | School point object ID |
| OBJ_ID_SAZ | INTEGER | - | Attendance zone object ID |
| OBJ_ID_DIS | INTEGER | - | District object ID |
| ALTID | TEXT | 80 | Alternate ID |
| ALTID_TYP | TEXT | 80 | Alternate ID description |
