The session packed a classroom at the mothballed school, leaving standing room only.
Since it was closed temporarily, Luing youngsters have been expected to travel by car, ferry and a public service bus to reach Easdale Primary School on neighbouring Seil.
At Monday's meeting, members of the community repeated allegations that a crucial council report carried out by Argyll and Bute officers as part of its consultation process so far was riddled with major inaccuracies and omissions.
Earlier this year an option to continue mothballing the school was rejected by the council, favouring a proposal to close it for good and adding Luing to Easdale school's catchment area instead.
Because Luing is an island school, there is an automatic presumption against its closure and if Argyll and Bute presses ahead with its proposal, the ultimate decision will be made by Scottish ministers.
Speaking at Monday's meeting, Save Our School lead campaigner Norrie Bissel said the council had "painted a false picture" in a report to decision-makers by saying there was "a mixed response" from the community.
Mr Bissel said there was no sign that officers had taken account of people's real views.
He reminded executive director Douglas Hendry with a responsibility for education: "How can we have confidence in the council and its consultation process if you can't even get that right?"
Mr Hendry said: "If this is a view that there are omissions and failures in the council paper then give us the details of things that are wrong and we will happily look at anything that comes in.
"We are open to listening in an open-minded manner to everything that is said to us. We might not agree with everything but the door is open to engagement."
The council's legal advisor said everything was being minuted and would be put in an appendix that would accompany the report when it goes to the next community services committee. People's concerns and allegations of omissions and errors would also go before Education Scotland.
Luing community councillor and Community Trust director Colin Buchanan also questioned the consultation process. "Frankly, we don't think we've been consulted. There are severe inaccuracies in what officers' assumptions are about our island," he said.
"We will have to beg to differ on this," responded Mr Hendry.
Community councillor Mary Braithwaite made a point that the report had been prepared without including any input from the island.
She said: "To close a school on an island that has had one school here for over 250 years is a huge issue. What we don't see in the report is any assessment on the effect that closure would have on the sustainability of our community."
Mum-of-three and community councillor Alison Young also said: "It does not seem you have taken into consideration how much closing the school will change our lives. We can't attend meetings, go to PTAs, there's lots of extra-curricular activities my child misses out on because of the not good enough ferry times. Nothing of that is noted or written down in that consultation document."
Another parent, Ed Pickett, wanted the report to be reviewed because of concerns about its "untrue" elements.
He also said: "Our children attend Easdale Primary School but they are not part of it. They are arriving at different starting times to the other children, missing trips and out-of-school activities. Surely that can't be right?"
Community Trust secretary Mary Whitmore said not mentioning the negative effects that closing the school would have on the economic development of the island such as its housing plans, the viability of businesses and ability to attract young families was another serious omission. "We really need all that to be put into the equation," she said.
Education policy lead Councillor Yvonne McNeilly said the council was not doing anything in an "insincere manner" and she "could go on in great detail" about how the council listened.
Education Scotland had a representative listening at the meeting.
The consultation ends on September 13.
