Gaelscoil Choláiste Mhuire has said that it is still very much dealing with the shock caused by the attack on Parnell Square last month.
Three children and a woman were injured when they were attacked by a man wielding a knife outside the school on Thursday afternoon, 23 November.
In a statement the school said that the community there "is still very much focused on dealing with the shock and the aftermath of the attack".
"We are all praying for the full recovery of our friend from the créche and our pupils directly affected by the attack and they, their families and friends are at the forefront of our thoughts."
The school said it was continuing to provide pastoral support - with the assistance of the National Educational Psychological Service "to our school community and this is going to be our main focus for the coming days and weeks".
Gardaí have said that there are no further updates on the condition of those injured in the attack.
A 5-year-old girl remains in a critical condition and a woman in her 30s is in a serious but stable condition.
A 6-year-old girl and a 5-year-old boy who had also been injured in the attack were discharged from hospital within a few days of the incident.
A man in his late 40s, who has been classified as a person of interest, is also currently in hospital in a serious but stable condition.
Last week, a GoFundMe page, set up to raise funds for the 5-year-old girl, who was critically injured in the attack, reported an update from the child's mother.
On Friday, on the fundraiser page entitled 'Barróg do Chailín Beag' (A Hug for a Little Girl), she thanked all those that that had assisted the family.
"Dear all, thank you so much for the incredible gesture and kindness you have shown our family during these troubled times. Your thoughts, prayers and generosity have and will go a long way.
"Our little girl has shown incredible strength and still here with us. We don't know yet what lies ahead as it is still early, but she is resilient and limitations will not stop her. Thank you so much. All the love we can give."
