For the 2013 academic year, the project has not yet handed out any tablets to students.
The new supplier will be chosen to replace Shenzhen Yitao Intelligent Control, which initially won purchase contracts but was unable to deliver the products.
The Office of Basic Education Commission (Obec) has confirmed that it has already terminated the contracts with Shenzhen Yitao Intelligent Control.
Caretaker Education Minister Chaturon Chaisang expected the Obec to call for bids within one or two weeks from now.
He hoped the tablet delivery from the new supplier would be completed by June.
Shenzhen Yitao Intelligent Control in fact won the contracts to deliver about 800,000 tablets to Prathom 1 students across the country.
