The current reporting period for the DS&PT is end of September 2020 to end of June 2021. Many practices may want to submit at the end of March to maintain the normal annual submission cycle which is expected to return to the end of March in 2022.
Part of the annual submission requires some technical evidence to be included and N3i have provided it in this spreadsheet.
A further spreadsheet that sets out all the requirements is here.
On 16th March 2021 the N3i IG Team did a presentation on the DS&PT and this can be viewed on YouTube here.
