The survey of 800 IT employers found that 9% of firms believe their IT staff have gaps in their capabilities that affect the business.
But 55% of companies of all sizes and 20% of those with 200 or more staff do not have any training plans in place. About 7% of the organisations carry out no IT training at all.
Businesses are also failing to plan adequately for their long-term IT staffing needs, the research suggested.
Just 66% of small and medium-sized companies and 69% of large organisations have IT recruitment plans in place.
IT suppliers and public sector organisations were most likely to plan ahead, the survey found, with the private sector less likely.
Only 9% of organisations look more than a year into the future when planning their IT staff needs.
