A basic strand in the mission of Public Employment Services is promoting labour market transparency, which is considered of importance for reducing unemployment and for improving patterns of labour allocation in several other ways. Self-evidently therefore, always a strong connection existed between PES operations and information and communication technology. Already the organization itself can be considered a social specimen of such technology. The ICT revolution of recent decades positively influenced general market transparency with a variety of easily accessible market places on the Internet. It also brought innovations to the PES. It changed the content of its services and the formats of their delivery. These things happened around Europe. Here the Dutch case is presented in more detail. ICT-induced innovations are followed over three subsequent stages from mid ‘80s onward. While the transformation of services was impressive and PES played a part in the increasing labour market transparency, its role in labour allocation has not noticeably strengthened. Its market share did not really increase. Neither did its contribution to less unemployment and/or a more equitably distributed entrance to job opportunities. Nevertheless, unexploited opportunities for the latter may still exist. Some are suggested for further exploration.
