Infrastructure Minister Dr Michelle Haywood says her department hasn't made any changes to bus schedules or routes in the wake of changes to school bus passes.
Last month the DOI revealed it was cutting the hours children could use their passes from 6pm to 5pm.
Ramsey MHK Lawrie Hooper put a question for written reply to Dr Haywood about service changes after the decision was made.
Dr Haywood, however, said there'd been no alterations to any routes or timings.
