California Code, Welfare and Institutions Code - WIC § 10819

The department may test the system in several counties prior to actual statewide implementation.  Criteria in selecting county test sites may include high dollar error rates for overpayments and payments to ineligibles, high administrative unit costs, size of county, and scope of data-processing activities.

The department may delay implementation of the system in counties where not cost effective.  If the implementation is delayed in such counties, the counties shall make available their data on a timely basis so that a statewide file on public assistance recipients can be maintained.
