The CALICE collaboration is performing R&D for the construction of highly granular calorimeters for a future dectector which will be operated at the International Linear Collider (ILC). The collaboration has constructed and operated several prototypes: A Si-W calorimeter ECAL comprising approximately 10000 pads, a hadron calorimeter with 7608 scintillator tiles individually read out by Silicon Photo-Multipliers and an ECAL which consists of tungsten plates and small scintillators read out via MPPCs. There is also a Digital Hadron Calorimeter concept (DHCAL) which uses resistive Plate Chambers with 1 x 1 cm^2 readout pads. We report on the commissioning and operation of the prototypes in test-beam, characterise the response of the detectors to electors and hadrons, and present the latest data compared to Geant 4 predictions. The test-beam results have delivered valuable information allowing the improvement of the layout for the next generation of prototypes, including a full scale calorimeter module being studied as part of the EUDET program.
