This volume is a collection of original articles published by the Astrophysics and Space Science Journal. These are the result of the work initiated in 2002 with the aim to - tensively test, compare and optimize the numerical tools used to calculate stellar models and their oscillation frequencies. This effort took place under the activities of the CoRoT Evolution and Seismic Tools Activity (CoRoT/ESTA http: //www.astro.up.pt/esta/) of the Seismology Working Group of the CoRoT Mission (http: //corot.oamp.fr/). It has been organized through the participation of the European Space Agency (ESA)...
