Training expert Catriona Standingford spotted the errors, which included old question papers and missing exam sitting information, as well as broken links.
She wrote on LinkedIn: “Very worrying - CII have 'revamped' their website but many essential pages which we know many candidates use now contain old information.
“For example, question papers and test specs from more recent sittings of J0 and AF exams have disappeared.”
She added: “Another example, the R06 case studies and AF5 fact-finds are now showing those from April.
“Just before the ‘revamp’, they were showing the October ones as you would expect.”
Ms Standingford, a board member of Financial Planning Development Hub and managing director of Brand Financial Training, also expressed “concern that the pages haven't been tested/reviewed before they went live.”
A CII spokesman told Financial Planning Today: “It is a glitch on one page which was missed in testing and is now being rectified.
“As far as the broken links, we are not sure to which the individual is referring as all seems to be working.
“As with most organisations the Chartered Insurance Institute is updating its website to ensure it is modern, relevant and engaging for its members and wider stakeholders.
“The first phase was implemented on 21 November delivering a range of immediate improvements, including, a mobile friendly responsive design, more intuitive navigation with improved user journeys, improved search functionality making it quicker and easier to find relevant content; and migrated content refined for relevance and accessibility.”
“These improvements provide the foundation on which further phases will build, giving members better functionality and greater personalisation.”
He said the changes were part of a “broader suite” of updates to the website.
The spokesman added: “Due to the sheer scale of the project there will inevitably be some teething issues during early phases of implementation and we value any feedback which helps us address these as quickly as possible.”
