Waiting Times

One of the stated targets of the IAPT programme is that for referrals finishing a course of treatment in the month, 75% access services within 6 weeks, and 95% within 18 weeks⁵. These are based on the waiting time between the referral date and the first attended treatment appointment.

91.2% of referrals waited less than 6 weeks to access IAPT services.

Calculating Waiting Times

In September 2021, this calculation is performed as follows: 

(Count_FirstTreatment6WeeksFinishedCourseTreatment / Count_FinishedCourseTreatment) * 100

(51,968 / 56,972) * 100 = 91.2%

Sub-national waiting times rates are published in the Monthly Activity Data File as columns ‘Percentage_FirstTreatment6WeeksFinishedCourseTreatment’ and ‘Percentage_FirstTreatment18WeeksFinishedCourseTreatment’.

The chart below shows that, nationally, waiting times measures have consistently been above the target, particularly the proportion seen within 6 weeks.

For an explanation of the terms used and further information about how measures are calculated in IAPT see the 'Guide to IAPT data and publications' at
