Filling the Sink turns the spotlight on education after Catalonia finished almost bottom of the class in Spain in the latest PISA international tests, sat by students around the world in reading, maths, and science.

The results have raised questions for Catalan schools: what's behind the decline, and what can be done about it? Have changes in education gone too far, or not far enough?

Oriol Escudé joins Lorcan Doherty to discuss the issues and hear the views of Mònica Nadal, research director of the Fundació Bofill, Xavier Massó, a secondary school teacher and general secretary of the Professors de Secundària union, and Toni Pedragosa, a secondary school teacher and member of the Clam Educatiu platform.

This week's Catalan phrase is 'Fer mans i mànigues'. It means to make a big effort to achieve something.
