Reuters has reported that Christians and Muslims in Minya, the home province of the 21 Coptic Christians beheaded by IS, have been promoting peace in schools.
The killings were quickly condemned by leaders of both faiths, and Ramen Atallah of Bible Society Egypt said the killings actually united people instead of dividing them.
"ISIS hoped that the killing would foment sectarian strife in Egypt between Christians and Muslims, but it has had the opposite effect," said Mr Atallah.
"Christians have responded by sorrowfully calling out to God, and Muslims have shown love and care towards them."
The scheme, which will see religious leaders meeting students to encourage a culture of tolerance and respect between different faiths, is supported by the Grand Imam of Al Azhar, Ahmad al-Tayyeb, and Patriarch Tawadrow II of the Coptic Orthodox Church.
But it has been reported that there has been tensions between some groups. A church being set up in memory of those killed in February was attacked on the same day that a commemorative mass was held to mark 40 days since their death.
It was being built in the hometown of the 13 Christians, Al Our village, and was attacked with petrol bombs in late March. The perpetrators are thought to be mainly young Muslims.
It was also reported that members of the Muslim Brotherhood, attacked the home of one of the martyr's family during the Mass service.
According to Fides, the Imams are all linked to al Azhar University in Cairo; a prestigious institution and the largest theological centre of Sunni Islam in the world. The Grand Imam has previously condemned the ideology of Islamic State, describing their ideas as "a perversion of the Islamic religion".
The Coptic Catholic Archbishop of Minya, Anba Botros Fahim Awad, said an inter-religious body called the 'House of the Egyptian family' was created years ago, but has been "and revitalized in recent times as a tool to prevent and mitigate sectarian conflicts."
An "upsurge of sectarianism" would endanger national unity, he added.
In total, 40 priests and Imams are part of the initiative, and it is hoped that the scheme will be rolled out across Egypt.
