A first vote will be held at noon on Tuesday. If that vote is passed, a decisive vote will then take place on Thursday.
The decision comes after EU member states last week made a new attempt to approve the extension, pending agreement on more permanent rules.
The European Parliament voted against the extension this spring, which would allow major internet giants to voluntarily search for child abuse material on social media. The fact that a change is now underway is explained by the legal uncertainty that has resulted from the no vote.
However, the proposal is controversial and is accused by online activists of leading to undue surveillance of emails and chats.
