The National Arts Fundraising School offers its first lesson to prospective candidates in its new brochure. It states: "We're so convinced that we can transform your fundraising that we offer a unique money-back guarantee. If within 12 months of completing the programme you have not raised a sum equal to the course fee, we'll refund every penny." The £1,762.50 course has been running for 13 years and its organisers say they have never had to return the fee.
