Resource | Research and Data | Payment Accuracy and Program Integrity Direct Certification in the NLSP: State Implementation Progress SY 2011-12: Report to Congress

Student eligibility for free meals is determined by application or by direct certification. Although direct certification systems vary by State and LEA, all such systems are designed to eliminate the need for paper applications. Effective in SY 2011-12, LEAs must conduct direct certification three times per year: once at or around the start of the school year, and again three and six months after that initial effort. All direct certification systems now match student enrollment lists against SNAP agency records and the records of other assistance agencies whose participants are categorically eligible for free meals. The matching process, whether automated or manual, requires no action by the children’s parents or guardians.

Resource | Research and Data | Assessing/Improving Operations Feasibility of Wider Implementation of Direct Verification With Medicaid

To ensure program integrity, school districts must sample household applications certified for free or reduced-price meals, contact the households, and verify eligibility. This process (known as household verification) can be burdensome for both school officials and households. Direct verification uses information from certain other means-tested programs to verify eligibility without contacting applicants. Potential benefits include: less burden for households, less work for school officials, and fewer students with school meal benefits terminated because of nonresponse to verification requests.
