Implementing the Part C Extension Option

If a State is implementing—or plans to implement—the Part C Extension Option, it must indicate so in Section II. A. 13 of their annual IDEA Part C grant application. However, both the State Part C Lead Agency, and Part B, Section 619 State Educational Agency must work with OSEP to develop a joint policy supporting the Part C Extension Option.

Before the application, the State should review—and possibly revise—their policies, procedures, and interagency agreements under the following:

These policies must also be approved by OSEP before implementation, and also subject to public participation requirements under 34 CFR §303.208.

If the appropriation for Part C exceeds $460 million, the Department of Education reserves funds to award State Incentive Grants (SIGs) to States implementing the Part C Extension Option. To receive a SIG award, your State must describe how award funds will be used in a separately submitted Section III, consistent with the following:

States' ability to offer the Part C Extension Option is not dependent on the availability or acceptance of a SIG award.

Procedural Safeguards

Consent must be obtained before the child reaches three years of age, where practicable.

The State must make clear which procedural safeguards apply for the eligibility determination under IDEA section 619.

The notice must:

The Part C lead agency must continue to provide all early intervention services identified in the toddler with a disability's IFSP.

This includes IFSP services consented to by the parent beyond age three until that toddler's initial eligibility determination under Part B. This provision does not apply if the LEA has requested parental consent for the initial evaluation and the parent has not provided that consent.

Written Notification to Parents

The State must provide families with an explanation of the differences between early intervention and preschool special education services.

This explanation must:

Individualized Family Service Plan (IFSP)

The State must ensure transition requirements are met.

Transition requirements apply to children receiving services under Part C before reaching age 3, including any those served by a State offering the Part C Extension Option.

The State must provide services that promote school readiness and incorporate preliteracy, language, and numeracy skills.

System of Payments (SOP)

The State must explain any differences due to State SOP policies to families.

The policy must clarify what parts of the State's system of payments on file for Part C (for example, public insurance, benefits, private insurance, or family fees) apply.
