The Child Maintenance and Enforcement Commission is responsible for the child maintenance system. I have asked the Child Maintenance Commissioner to write to the hon. Member with the information requested and I have seen the response.
Letter from Stephen Geraghty, dated 24 February 2010:
In reply to your recent Parliamentary Question about the Child Support Agency, the Secretary of State promised a substantive reply from the Child Maintenance Commissioner as the Child Support Agency is now the responsibility of the Child Maintenance and Enforcement Commission.
You asked the Secretary of State for Work and Pensions how many cases under consideration by the Child Support Agency involve absent parents in (a) Scotland and (b) Perth and North Perthshire constituency. 
I have interpreted ‘under consideration’ as cases where an application has been made but which has yet to be cleared.
The Child Support Agency's performance has continued to show improvement over the last quarter, building on the stable base provided by successful completion of the Operational Improvement Plan in March 2009.
As at December 2009, the number of uncleared cases in Scotland was 2,120, which represents a 20% decrease from 2,650 in September 2009. In Perth and North Perthshire Parliamentary constituency the volume of uncleared cases fell from 55 in September 2009 to 45 in December 2009. These figures include both old and current scheme applications and those cases administered clerically.
Nationally, uncleared applications fell to 28,900 in December 2009, which is a 6,300 (18%) reduction from September 2009.
I hope you find this answer helpful.
