Do you want me to take that one? I'll take that one as well. Thank you. So, as we set out in the annual report and accounts, we voluntarily submit ourselves to quality review by the quality assurance department of the Institute of Chartered Accountants in England and Wales, and this is something that I am very passionate about, and I am very pleased with the results that our teams were able to achieve this year. I'm always a little wary, because it's a sample-based review, and there is always a risk that, this year, they picked really, really good audits, and that, next year, there might be one or two where the results are good, but they won't be quite as positive. We had three financial audits this year that were in the very highest category that can be awarded.
So, I think it reflects the significant investment that we've made over the last few years, in large part, actually, thanks to your predecessor committee, who provided us with additional funding to support this. And we have invested a lot in our audit development and guidance team. So, we have employed an additional member of staff in that team, to help us in terms of making sure that our staff receive the guidance, the training that they need. That's really important, because people are huge in that quality space, as you'll be aware. We also invest significantly, as you'll be aware, in our trainee scheme. And we bring in, every year, 12 to 15 graduates, and people straight from school, to train them through the associate chartered accountant qualification. And we really do invest in those individuals.
We've invested in technology and tools. In our performance audit work, we've adopted INTOSAI—International Organization of Supreme Audit Institutions—standards as well, which are internationally recognised standards for performance auditing. We have worked very closely with the Chartered Institute of Public Finance and Accountancy, the accountancy body, to support the new performance audit qualification. We work closely with the institutes themselves, we have very good relations with the accounting bodies, and with the other PAF bodies, the public audit forum bodies. We worked very closely, for example, with the Northern Ireland Audit Office to bring in a new methodology and write a new audit manual, following the introduction of the new auditing standard, international standard on auditing 315, a couple of years ago.
We've set up technical networks, so, hopefully, you're getting the picture that we have invested significantly in this space. For me, quality—and I know for Catherine too—is absolutely everything. Our reputation, everything, rests on the quality of our work. And so it's an area that we absolutely have to have at the forefront of our priorities.
