Jamie Hepburn MSP has responded to a report by Police Scotland looking at the walking routes for pupils moved from the closure-hit Abronhill High School.
He is backing parents who plan to launch a legal battle to save the school, which featured in hit film Gregory's Girl. The school is earmarked for closure at the end of this school year and youngsters will be moved to Cumbernauld High.
Police Scotland has now made recommendations to improve the safety and amenity of walking routes from Abronhill to Cumbernauld High School.
Mr Hepburn said: "It is now incumbent on the council to respond to this report.
"There will continue to be understandable concerns about pupils using such a remote route.
"This, along with the severe impact on the community of Abronhill through the loss of the High School are reason enough for the Council to ditch their plans to close Abronhill High."
In February, North Lanarkshire Council approved a recommendation to shut Abronhill and move 480 pupils to Cumbernauld High.
Campaigners took their battle to Holyrood, but the Scottish Government conditionally approved the move as long as safety measures are implemented on the route pupils would take to Cumbernauld High.
A police report specifies additional lighting and litter bins should be put in place along routes as well as removal of graffiti.
Routes near a railway line must also be checked for safety.
James McKinstry, Head of Resources, said: "Police Scotland has now produced their report and it is worth noting that there are no major areas of concern highlighted.
"It's our intention to meet the parent council chairs to advise them on the action we will be taking."
