Enhance Media, the recruitment research company behind the annual U.K. National Online Recruitment Audience Survey, says a record number of job boards will participate next year.

The company says that the survey is the U.K.’s largest online recruitment research project. In 2009 it surveyed more than 50,000 candidates across 31 online job boards– and was then used by more than 10,000 subscribers to help them select the right job board for their recruitment needs.

For the 2010 survey, Enhance Media says that more than 60 leading U.K. job sites are already signed up to take part. The company predicts the NORAS will double in size.

 “The dramatic increase in the number of job boards participating in NORAS proves that there is a growing demand for metric based analysis in the online recruitment market,” said Giles Guest, Enhance Media’s managing director.
