The whistleblowing charity Protect is inviting charities to take part in a free pilot project to assess the strength of their whistleblowing cultures.
Protect has recently developed the 360 Benchmark tool, which examines whether a charity is set up to allow its staff to report on wrongdoing safely and effectively, and is offering charities the chance to trial it.
Interested charities with 50 or more employees are being invited to a discussion in October, where they will be able to sign up to the pilot.
Protect said in a statement that it was looking for between 30 and 40 charities to take part, and spaces would be allocated on a first-come, first-served basis.
Once the project was completed, information from the charities would be analysed and discussed anonymously, it said.
Francesca West, chief executive of Protect, said: "Following the very well-documented Oxfam scandal, we recognise there is much to be done to support the third sector."
She said the charity wanted to offer access to its 360 Benchmark "to a cohort of charities to help them understand where they might be falling short on best whistleblowing or speak-up practice".
Charities that are interested in taking part in the 360 Benchmarket pilot should contact Lou@protect-advice.org.uk by 18 September.
