A sample of 26 Compact Steep Spectrum sources selected from the original list drawn up by Dallacasa & Stanghellini (1990) have been observed with the VLA A‐array at X, U, and K bands. Images have been produced in both total intensity and polarisation at four widely‐spaced frequencies with the aim of deriving linear polarisation parameters. We present preliminary polarisation results on source fractional polarisation and electric vector angle at X and U bands. These new information will be completed with available archive data in order to perform a polarimetric analysis of a complete CSS sample (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
