The Improving Access Psychological Therapies (IAPT) data set is a regular return of data generated by providers of IAPT services in the course of delivering these services to patients. The data also includes information from Independent Sector Organisations who are also providers of NHS IAPT services.
The IAPT data set is received by the Health and Social Care Information Centre as record-level anonymised data from patient administration systems.

Data quality and completeness

A data quality statement is produced for the Routine Quarterly Reports and can be found in the related links below. 

A separate monthly publication comprises national and provider level data quality measures of some key data items in the IAPT dataset and the latest release can be accessed in the related links below.


Experimental analysis by CCG and month for Q1 2013/14 was added to this release on 18 November 2013 for assurance purposes.  We welcome feedback on the usefulness and relevance of presenting the data in this way.


In addition on 18th November a typographical error was corrected in the Data Quality statement and in the IC_Derivations tab of the Commissioner and Provider level analysis.
