IT professionals are being deterred from updating their skills by the cost of training courses.
Of 100 IT professionals surveyed by IT training supplier Thomson Netg, 50% cited cost as the main reason for not taking a course to boost their skills.
The research found that 36% of IT staff expect they will have to pay for courses out of their own pockets.
The survey follows a report earlier this year by Forrester Research, which predicted that European businesses would suffer an IT skills shortage in 2006.
Thomson Netg director Mike Summers said, "Although training is still a concern for European businesses, there is a lack of impetus for HR departments to invest in improving the skills of their workforce."
According to the survey, the Microsoft certified systems engineer course was the most popular training option.
