Solihull MP Lorely Burt is calling for a public meeting to be held for parents to have their say over plans to merge Hatchford Brook School with Valley Infants.
More options have now been put forward by Solihull Council to help decide the future of both schools after councillors and residents raised concerns over plans to build a joint school on the Hatchford Brook site.
Concerns have also been raised over a lack of consultation with residents.
“Parents have not been kept in the loop,” Mrs Burt said.
“They want their say and I think it is incumbent for the other stakeholders to listen.”
Alternative options, due to be discussed by cabinet, include having a primary school on both sites or an infant school on one site and juniors on the other.
Councillor Martin Hewings (Lib Dem, Elmdon) added: “What we would have liked is for the parents to be more involved in the discussions.
“Having a separate juniors and infants seems to have more of a management logic to it. St Alphege operates in that way and it seems to work well.”
Reacting to the criticism, a council spokesman said last week: “Unfortunately Hatchford Brook has been through a difficult period, including a previous adverse report from Ofsted.
“The risk of not taking decisive and prompt action is that pupils continue to not receive the quality of education which they deserve.”
