Waiting Times

One of the stated targets of the IAPT programme is that for referrals finishing a course of treatment in the month, 75% enter treatment 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.

92.8% of referrals waited less than 6 weeks to enter treatment

Calculating Waiting Times

In December 2020, this calculation is performed as follows:


(Count_FirstTreatment6WeeksFinishedCourseTreatment / Count_FinishedCourseTreatment) * 100


44,642 / 48,111 * 100 = 92.8%

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
