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:
- Section II. A. 3a — System of Payments (SOP)
- Section II. A. 3b — Methods
- Section II. A. 9 — Transition Policies and Agreement
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:
- 34 CFR §303.205 — Description of use of funds
- 34 CFR §303.501(d) — Permissive use of funds by the lead agency
- 34 CFR §303.734 — Reservation for State incentive grants
States' ability to offer the Part C Extension Option is not dependent on the availability or acceptance of a SIG award.
