DAPB1520: Improving Access to Psychological Therapies Data Set

The Improving Access to Psychological Therapies (IAPT) Data Set collects information about adults in contact with psychological therapy services.

About this information standard

This information standard provides national definitions for the collection of IAPT data, allowing providers to extract data from their local systems in a consistent manner which enables national and local reporting to be undertaken.

This information standard is published under section 250 of the Health and Social Care Act 2012. An Information Standards Notice (see below) provides an overview of scope and implementation timescales, and the other listed documents provide further detail for those who have to implement the information standard.

July 2021: Note: While implementation activity for IAPT v 2.1 may start immediately, the Enhanced Technical Output Specification, Data Model and User Guidance will not be published until later in July 2021, on the NHS Digital IAPT web pages. 

Version 1.5

 Documentation for earlier, superseded versions of IAPT can be found on the on the archived Information Standards Board website.

Change control

Update 29 October 2019: The latest release (DCB1520 Amd 14/2019) was published on 5 September 2019.  Following publication, the need for a minor correction to the data set was identified and a Corrigendum has been issued. Note that there is no impact on either the published Requirements Specification or the Implementation Guidance. However an updated Change Specification and Data Set Specification, dated October 2019, have been issued and should be read in conjunction with the Corrigendum. 

If you have any questions about this Corrigendum, or other IAPT issues, you can contact the developers by emailing:

Update 6 August 2020:  Due to COVID-19 activity, version 2.0 of the IAPT Data Set will now be collected locally from 1 September 2020 with national submissions commencing on 1 October 2020 for September 2020 data.
