Data as of January 2009. Joint renewal indicates that the same renewal form is used for children's Medicaid and SCHIP. In a number of states, separate Medicaid and SCHIP renewal forms can be used to determine eligibility for both programs, however for the purpose of this data, joint renewal indicates that the same form is used for the both programs.
"Regular" Medicaid refers to coverage under Medicaid eligibility standards for children in place prior to SCHIP; states receive "regular" Medicaid matching payments as opposed to enhanced SCHIP matching payments for these children.

SCHIP: State Children's Health Insurance Program.
Aligned Medicaid and separate SCHIP: Indicates the number of states that have adopted a particular enrollment simplification strategy and have applied the procedure to both their children’s Medicaid program and their SCHIP-funded separate program. States that have used SCHIP funds to expand Medicaid exclusively are considered “aligned” if the simplified procedure applies to children in the “regular” Medicaid program and the SCHIP-funded expansion program.
NA: Not Applicable because state does not have separate SCHIP program.
