Question to the Department for Work and Pensions:

To ask the Secretary of State for Work and Pensions, what steps she is taking to ensure the accuracy of the (a) systems and (b) IT used by the Child Maintenance Service.

Regular updates ensure the Child Maintenance Service's systems comply with policy. Each change follows industry standards, including thorough testing before and after implementation. The core principles for calculating Child Maintenance have remained largely unchanged since 2012, with no current system defects affecting these calculations.

The Department for Work and Pensions rigorously monitors accuracy, with the National Audit Office setting a target of monetary value errors under 1%. This standard is consistently met.
