Hi NW Mapper 2024, thank you for commenting to raise this. Having worked on School Bus routes around Greater Manchester, access roads on School grounds are not usually assigned the Private tag - therefore the software used to route bus services is not in error here.

The change here (and at East Manchester Academy) was made to bring this access road in line with others across the region - examples of other nearby School with access roads without private tags include Cedar Mount Academy (https://www.openstreetmap.org/node/11145708441#map=19/53.450654/-2.174279) and Wright Robinson College (https://www.openstreetmap.org/way/447542601)
