The RKEO team aim to provide you with tools to writing a successful application. As part of this, you can find all sorts of information in the Research Toolkit on this blog. Just look up to the top-right hand corner of the blog and you will see the link on the menu bar.
As well as specific guidance on writing sections of research council applications, there is also advice in the form of quick guides for various activities, access to concordat information, as well as advice on ethics and outputs. Do explore what is available to you and let us know if there is anything else that you would like to see included.
