The international charity ActionAid Ireland has described orders issued to lone parents in Direct Provision to move to alternative accommodation by mid-September as "scandalous".
Letters have been issued to mothers who had purchased school uniforms, and who now have to "scramble" to find school places for their children after being told they have to move from their communities.
In May, letters were sent to women with children living in Direct Provision who had received international protection status instructing them to leave their accommodation by 5 July.
However, ActionAid Ireland claims the situation was mired with confusion, due to a failure by the International Protection Accommodation Services (IPAS) to provide a coherent follow up to the eviction notices.
Some parents received follow up letters saying their new moving deadline was 18 July, while others received letters stating that their cases were under review and that they would be contacted "in a few weeks".
Women supported by ActionAid Ireland received phone calls at the time informing them that they would not be transferred due to a lack of available space in emergency accommodation, which it has said left them "in complete limbo".
Head of Programmes at ActionAid Ireland Grainne Kilcullen has said the Government has continuously failed to treat people with dignity and respect.
She said the situation has been "actively causing trauma, distress and anxiety among mothers and children during an already very difficult time in their lives".
She said the women and children had been left in "complete limbo" since the first eviction letter was sent three months ago.
"They have delayed buying uniforms and other school materials until this week because they don't know where their children will be going to school in September.
"Now, only a few days out from returning back to school, parents and children have received notifications that they will be transferred by 16 September.
"In other words, the Government is forcing them to desperately scramble to find school places, special needs assistants and medical support for their children, uprooting them from their communities, services and routines," she said.
One mother who has been living in a Direct Provision Centre in Ballyhaunis, received a letter from the Department of Integration yesterday which said she had reached the stage that she "must now progress to independent accommodation in the community".
The mother - who said she has no hope of securing private accommodation due to lack of supply and cost - waited until yesterday to buy uniforms for her children only to receive the letter today.
The letter said if she was unsuccessful in sourcing alternative accommodation, IPAS would provide alternative emergency accommodation in Ballina from 16 September.
ActionAid has said a move to Ballina would involve moving to a new school.
The charity has renewed its appeal to Minister for Children, Equality, Disability, Integration and Youth Roderic O’Gorman to exempt lone parents with international protection from having to vacate their Direct Provision accommodation.
The charity said: "The exemption to people over 65, or with health needs, to stay in Direct Provision must be extended to parents with children. It is simply not acceptable to ask vulnerable women and children to be out of their accommodation.
"So many of these women have already suffered huge trauma and have been uprooted from their homes and forced to flee to Ireland in the first place due to conflict or crisis."
In a statement last month, the Department of Integration said that while it appreciated transfers were not easy for people and that moving location could be very disruptive, "at all times we were clear that State-funded accommodation is temporary and subject to change".
"We need to provide the best we can for all those who came to Ireland fleeing the war in Ukraine, while balancing this with the requirement to make best possible use of State funds," the statement said.
Speaking on RTE's Morning Ireland, Ms Kilcullen said: "What is really scandalous is that the Government have been talking about the importance of integration for people coming out of direct provision, and it's undermining all the efforts that those families and their children have been making, over the last number of years, to integrate into the community and to be able to contribute as well in the community".
