Parents in North Yorkshire say they have been forced to investigate school catchment lines and travel distances to secure free school bus passes after a council policy change restricted entitlements.

Under national rules, secondary school pupils are eligible for free transport if they live more than three miles (about 5km) from a school. North Yorkshire Council has altered its policy so that pupils starting secondary school this week will now receive free travel only to the nearest school, rather than to any school within their catchment area.

The change has prompted families living in villages near York to say they have had to "turn into detectives" to challenge decisions and prove eligibility. The BBC reported that at least three families described feeling "worry" and "dismay" during the summer holidays as they tried to establish which school their child would be eligible to travel to under the new rules.

One parent, identified as Ruth, who lives in Appleton Roebuck, said she discovered the policy change only after a WhatsApp group of parents raised concerns; an official email notifying families went to her junk inbox. According to figures cited by the council, Ruth's home is 0.004 miles (6.4 metres) closer to Millthorpe School than to the alternative, a difference that has become central to the family's appeal over a bus pass.

The council acknowledged the revised policy was "not generous" but defended the move as necessary to save money. North Yorkshire Council said the change would reduce costs associated with transporting pupils to multiple schools across catchment areas, though it also recognised the impact on families who had expected different arrangements.

Parents described using online mapping tools, distance measurements and council records to assemble evidence for appeals and to argue that some pupils should be entitled to travel to a particular school within their community. Some said they had taken time off work during the school holidays to investigate the policy and pursue appeals, adding to the stress of arranging new routines for the start of term.

Local authorities are responsible for implementing home-to-school transport policies within the framework of national legislation, and many councils have reviewed eligibility criteria amid funding pressures. In North Yorkshire, the latest change has sharpened tensions between cost-saving measures and families' expectations of continuity, particularly where historic catchment boundaries and community ties point to different schooling arrangements.

Parents and campaigners have called on the council for clearer communication and greater flexibility in assessing individual cases. The council has said it would consider representations from families affected by the policy change, but maintained that the revised approach is required to balance service provision against budget constraints.

As the school term begins, some families are continuing to pursue appeals and request reviews of distance calculations, while others have begun to make alternative transport arrangements. The dispute illustrates the practical challenges that can arise when local authorities alter long-standing eligibility rules for school transport, and the extra burden that can fall on parents navigating those changes.
